Large stones cannot be directly used directly for various purposes. For this reason, a stone crusher is needed so that the stone is small in size so that it can be used immediately.

Cone crushers are one of the most common types of stone crushers. They are used to reduce the size of large rocks and minerals into smaller pieces and granules. They are used in various industries. such as the mining, metallurgical, constructive and chemical and phosphate industries. They can also be used for social or governmental projects, eg. B. for railway rehabilitation and road construction.

Components

A cone crusher is a very complex machine that consists of many components, but whose main structure is the same, consisting of:

•     Main axis
•     Against axis
•     The feathers
•     Manganese

Stone crusher can simple until complex machine

Main axis: is used to assemble the spirit. It is supported by the bearing on the base and fastened under the mantle. The main shaft itself does not rotate, driven by the bevel gears rotated in the opposite axis. In reality, however, it is housed in a rotating environment.



Counter-axle: The counter-shaft generates a rotary movement in the cone crusher. On the outside of the tree is a pulley and inside a pinion. The gearbox drives the housing of the eccentric main shaft.

The feathers: Large springs are part of the safety mechanism in cone crushers, which prevents damage to the course by harder and stronger rocks. Press the upper structure down to prevent hard stones that can not be crushed from moving and damaging the crusher as they enter the cavity.

Manganese mantle: The manganese mantle is one of the grinding surfaces of the machine in question, ie the cone crusher. Make a spherical twist through an eccentric rag, like an ice cream cone machine that fills the material into the cones!

Business

The working principles of the cone crusher are similar to those of rotary crushers with a more parallel zone and less inclination in the crushing chamber. As a result, the rocks are broken by being crushed and crushed between the spindles, turning eccentrically and surrounding the concave funnel. The rotating spring is covered by the wear-resistant sheath and the concave funnels by the lining of the manganese bowl or concavity.

The grinding chamber is the area between the cone and the moving cone. When the stone or ore enters the cone crusher from above, it remains in the upper zone and is compressed between the lining of the bowl and the mantle. The large parts break and they are allowed to fall to the lowest position, where they are broken again. This process lasts until these pieces are small enough to escape through the narrow opening available for these parts in the lower part of the machine, ie the lower zone.

The advantages

Cone crushers are one of the most advanced and efficient types of rock breakers. They offer many advantages, including the high milling content, the thin and even size of the product, the low energy consumption and the good granule products. They consist of ultrathin and energy-efficient rock elements. They use the principle of the sliding cover and cover a wide range of products. Its free space in the cavity is more practical than any other type of crusher machine. The use of high performance rock, shaft diameter and a separate lubrication system ensures the reliability and longevity of the machine.


For example, The United Kingdom has a rich mining history: There are several types of industrial minerals. The most common industrial minerals are sand, gravel and cement, which are used in construction products and in road construction. In the UK, many slate mines produce shale, which is then used for construction and architectural purposes. There are slate mines in England and Scotland, but most are in Wales. In the United Kingdom, there is also a large amount of other minerals, such as Chinese clay, used in fine porcelain and porcelain, especially in the Pottery region of the West Midlands (where most producers are located). fine china) and on earth. Fuller, an absorbing mineral used to absorb spills and cleansers. In Great Britain, stone mining requires state-of-the-art shredding technology and a high-quality crushing plant for quarries. If you want to find a manufacturer of stone breakers in the UK, a simple Google search will help you find them.

Stone crusher serves to break the stone up to a small size so that it can be used

In the first phase of grinding: Imagine you have to cut cheese, you can make pieces with a hand, a knife or something else, such as a grater. Imagine, if the meat you want to cut is meat, then a knife is the only option. You really can not cut it to pieces by hand. If the material is hard, you can only use a shredder. To crush stones, you need something like a jaw crusher or an impact crusher from a manufacturer. Theoretically, it's better to work with a model that does not wear out too quickly. Efficiency and reliability are the most important things.

It is clear that a stone crusher is essential for heavy work such as the decomposition of large quantities of rock material and is also a good manufacturer. The device must operate reliably over a long period of time, coping with high workload and productivity. The stones are crushed into the jaws of the machine into smaller pieces, which can then be used for other purposes or as minerals from larger rocks. This is particularly important in the mining process, where mines cause a large amount of waste. The stone-crusher manufacturers focus on these key qualities as they create new equipment and explore new techniques: they observe what their current equipment is used for, and then market new versions on the market that companies can buy. They are the best. Technology available


Either inefficient machines can slow down production, increase downtime, and unduly burden your profitability, whether you're working in construction, highway, or mining. Failure to meet the deadlines can also damage your reputation. You need to use cone crushers that increase your profitability by offering more than promised and faster than expected.



A cone crusher is an important part of your stone or mineral processing process as it grinds the material to the desired dimensions. Since this process is usually secondary in the crushing plant, some processes depend on crushing in a timely manner, so that the entire process chain functions as a smooth, well-oiled machine. Hammer and jaw crushers are other types of crushing systems. But when you need cone crushers, you need a reliable and robust machine that will not leave you at the center of your project.

Nordberg is one of the many well-known companies that makes tough cone crushers. The company manufactures various models of cone crushers through its HP or High Performance range to suit different sectors and requirements, including ballast, sand, taconite, limestone, etc. Nordberg will most certainly be transporting a shredder for transport between different locations ,

The company's mobile crusher can be pulled anywhere, using a closed loop crusher and sifting process with a conveyor belt to quickly shred the bricks in three different designs. The company's machines enable faster shredding due to the patented technology, which allows for faster speed and longer start-up and better performance than the crusher. The particulate release safety system, coupled with a fixed setting that allows for better stability and lower deflection, ensures that castings are easily ejected while maintaining consistency in the production of finished bricks or minerals.

How the stone crusher works to break rocks

The technological features of several Nordberg cone crushers provide benefits in terms of ease of maintenance as all interchangeable parts are easily accessible. Among other benefits, there is less downtime due to its superior ability to eliminate stragglers and very low maintenance costs through the use of superior labyrinth seals, bronze rings, and most parts of each mill are easily interchangeable. These breakers also have a very flexible design. By simply exchanging some key components, you can switch your crusher from the thickest to the thinnest void. All of these features result in greater savings, less downtime, and faster delivery of the required raw material, increasing your ROI and improving your reputation.

You need a company that not only manufactures rugged and energy-efficient crushers, but also provides after-sales service in the event of a problem. A company that is present in many countries and cities should be privileged as it can communicate with you as quickly as possible. Companies like Nordberg can guarantee that their cone crushers perform better than they expect, while the design and performance of these crushers allow for easy maintenance in case of scheduled maintenance or unwanted problems.

In earlier versions of concrete breakers and rocks, two stones were used, which struck each other. One anvil was made of one stone while the other's weight was used manually to achieve the necessary size reduction. A crusher named Cornwall Seal was developed in the 19th century to break the can and was used in mines. The early years of the 20th century led to the development of portable stone breakers.

Simple concrete consists of three components: water, aggregates and Portland cement

It is used for the construction of sidewalks, foundations, utility structures, roads, bridges, other architectural configurations and even bowls and works of art. The amount of water is important as it can affect the durability of the concrete. It is imperative to add sufficient water during the mixing and curing phase. Water reacts with the cement throughout the process to form a stone-like material, commonly referred to as concrete. The aggregate is usually made of rock, sand or gravel, but there are many other additives depending on the desired result. There are a number of aggregates that can be added for different purposes. Aggregates give concrete structure. You may think it is an advertisement for Portland cement. This is not because Portland cement is not a special brand. It is a cement type and can be manufactured by several companies.




Portland cement is a mixture of calcium, silicon, aluminum, iron and minor amounts of other ingredients. It is the basic component of concrete and can be controlled by adjusting the setting time with gypsum. Water and cement form an adhesive-like mixture that covers aggregates and joins rock and sand during drying and curing. One way to optimize your project is to use the right amount of fine to large aggregates while using the largest possible aggregate. Water reacts chemically with the cement during an exothermic reaction. The faster the setting time, the less time you have to work after casting with the concrete mix. The amount of water in the mixture compared to the amount of cement is referred to as the water / cement ratio. The lower the water / cement ratio, the more resistant the concrete and the less permeable.

In the manufacture of prefabricated septic tanks, it is very important to understand the permeability of the final product. In any construction project, it is important to build a road or a house to know the strength and wear resulting from the structure. In the southwest, sun and drought are important factors, while in the northwest the humidity level should be considered. In cold climates, freezing and thawing concrete must be calculated. The expansion of concrete is an aspect to consider. On bridges, you often see small gaps in the road to heat and cool the concrete.

Concrete is the most widely used synthetic material in the world. If you look around, you will see it wherever human beings live on the earth. If you're driving on highways, even if it's not concrete, you'll see concrete barriers used to separate the road or protect workers on the streets. Concrete is used in construction projects, from the largest dams in the world to nest boxes in the backyard. It is an amazing and versatile material, limited only by imagination.

Concrete stain: application areas, preparation and application of the stain

There are three important points to consider when applying your concrete stain: application areas, preparation and application of the stain.

Applications: Acid Stain can be applied to all cement surfaces such as corridors, access roads, lounges, bathrooms, terraces, floors and busy areas. It should be noted, however, that not all types of concrete floors are suitable for dyeing, although maturity is not a problem, but the condition. The softer the surface, the better the result compared to older floors. Older soils, however, contribute to an indispensable character, with errors and imperfections merging with the overall picture. The dye does not react well and gives the desired result when the concrete granules are exposed to acid or pretreated, since the granules do not react to the dyeing process. In terms of structured surface application, such as punched or stamped concrete layers, concrete dye provides a depth of color and a beautiful realistic appearance of the surface.

Preparation: The preparation of the coloring depends exclusively on the condition of the concrete. The new concrete must be cured about three weeks after pouring, rinsing and scrubbing to remove debris and dirt. In the case of old concrete, the preparation involves a thorough cleaning of dirt, grease, paint or putty, which prevents the absorption and reaction of stains. It is recommended to always carry out a preliminary reaction test in a small area. Begin your color project with preparation and planning and then continue with the application.

Application of stains: The application of real stains requires only a few tools. Various sprinklers, brushes and a diamond saw are required to delineate the surface. First, test your hand with a simple design and then move on to more complex and challenging projects. Remember, the more complicated your design is, the harder it gets. It is imperative to seal or polish the tinted floor after the process to protect the stain and add depth and shine.

Access roads such as concrete

Since a driveway can dramatically affect the attractiveness of a home, the landscaping options and the value of the property, it is important to choose a well-designed path that suits your needs. The owner of a property has several options for access roads such as concrete, gravel and asphalt, with each material having its own advantages and disadvantages. For example, a well-built concrete road is a popular option and has many advantages, including:

Functionality: In terms of structural strength and long-term integrity, concrete is high on the list for highly functional materials. A concrete pavement is extremely durable, which means that this option is less likely or damaged. So perfect to accept even the biggest SUV without showing signs of surface deformation, even after a long break, due to the weight of the vehicle. A properly poured concrete road can take more than 30 years. On the other hand, a unit of gravel or asphalt needs to be replaced or replaced frequently.

Improving the Appearance of Properties: A concrete pavement no longer has to consist of a smooth, flat slab of slate gray or similar color. It is now possible to create entries with a wide variety of eye-catching patterns, with multiple options for colors, textures, and patterns. The patterns offer very flexible options with a choice of brick, paver or swirl patterns. Colored, textured or polished concrete can effectively increase the attractiveness of properties.

Low maintenance: A concrete road is very resilient and therefore requires little work to maintain the overall appearance. In most cases, stains and stains can be removed with warm water and soap, while stubborn stains can often be removed with a dry grain cleaner. In addition, a solid surface like concrete is very easy to clean the snow.

Economy: Due to the long service life of the concrete surface, this road material offers a high degree of economy. Although the cost of setting up the interface is not cheap, this initial investment pays off quickly as it can increase the market value, appearance and overall functionality of a property.

Respect for the environment: It is often stated that concrete offers environmental benefits. An entrance area of ​​this type can be made with various recyclable materials. Concrete can also reflect light, which can reduce the number of external night lights. Finally, at the end of their useful life, the driveway can be recycled into concrete aggregates or granular back fills.

Several studies have shown that most mining costs are spent on transporting material. When looking at the cost chain, from drilling and blasting to the storage of large crushed material, transportation is generally 40-60%. So, if you're looking for resources, you can cut costs. The transport process must therefore be carefully analyzed. A comparison of the cost of transporting rocks on the road and in traffic shows that they can save up to 70-80%.

It is well known that the original material of the rock to be conveyed by conveyors is usually milled to the maximum size of a work piece, usually 300 to 400 mm. This demand led in the 1950s to the development of semi-mobile and mobile equipment for large scale crushing. The design of such machines was initially a "solid breaker that was converted to a mobile device", which made them very heavy and difficult to move. In general, these machines have changed installation locations once or twice during one working month.

Since the mid-1980s, the situation in the non-metallic industry has been similar to that in other areas of mining. Almost all major breakers were stationary or mobile in a mobile chassis. In 1985, the world has already seen a new type of mobile tracking device that meets the needs of non-metallic material manufacturers who often transport their equipment on public roads. On this basis, larger and more productive crushers were created to maintain high mobility. These machines move around the plant during the day and open up new possibilities for planning the field development and loading possibilities for the material to be conveyed.

One of the criteria for the evaluation of a transport system is the cost of the end products. Below is a comparison of the cost of transporting products via conveyor belts and vehicles with an analysis of their sensitivity to various operational factors.

The use of conveyor belts can be used for long distances

On the other hand, the fleet of dump trucks is limited both in terms of minimum and maximum distance of freight traffic, and at short distances it often does not fully exploit the potential of its performance:

- With a delivery distance of 1.0 km, the price difference of one tonne of products is extremely remarkable and the reimbursement will be reached in about 2 years.





- At the time of delivery at a distance of 5 km, the cost of transporting a tonne of freight is even lower than for road transport. Due to the large capital investment, the recovery phase increases at about 15 years.

Since then, the number of mobile crushers in the caterpillar used in the industry has increased. In the production of non-metallic materials, for example, three-stage crushing and sieving complexes are not uncommon.

Rising fuel prices and expensive truck tires have a negative impact on production costs. Properly used, mobile crushing and screening equipment, in combination with the transportation of the conveyor equipment, provide the undeniable advantage of using all equipment.

With increasing annual transport volume, the competitiveness of conveyor belts increases

This can be explained by the fact that relatively little investment in the extension of the transport of conveyors can significantly increase their productivity.  The payback period has been reduced to about 8 years.
The value of the total inclination angle of the transport route.

The steeper the ascent, the greater the advantage of a conveyor system. This is mainly due to a decrease in speed and increased fuel consumption of dump trucks when driving on roads with higher elevation angles. On the other hand, conveyor belts require high performance units to overcome steep climbs. Figure 4 shows the transport costs of 1.0 million tons of iron ore per year over a distance of 5.0 km on the roads with an increase of 8%. Under these conditions, the repayment period is also already shortened in about four years.

Reducing the use of automobiles will still reduce the negative impact of mining on the environment

Trucks are the main cause of harmful effects in the form of exhaust fumes, dust and noise. According to international agreements, the permissible emission levels of diesel engines have been significantly reduced, but the effects are increasing. Replacing lorries with electrically operated conveyors completely eliminates these harmful emissions. For example, the dust generated during the movement of vehicles can be removed with water, however, these measures require expensive equipment and never eliminate the problem. Conversely, conveyor belts with dust protection solve the dust problem.

At the same time, moving the dump truck poses a constant threat to the health of a nearby person. Therefore, road and quarry accidents still occur, regardless of compliance with safety regulations. However, to be fair, it should be kept in mind that conveyor belts that significantly reduce industrial risk do not completely eliminate it.


To organize the efficient operation of dump trucks in a quarry, a mountain is much larger than required for the installation and maintenance of conveyor belts. When a sloped deposit is being developed, the sides of the well bore may be exposed to higher angles, thereby reducing the overload coefficient and final excavation volume. In developing some careers, this can have a critical impact on production costs.

Mobile operations are needed because of excavations in different places

Mobile crushers are extremely versatile for two reasons:

• They are the equipment of the standard model range of most manufacturers and as a result the delivery orders will go through fairly quickly.
• You can easily move from one object to another and get up quickly after the next move.

These advantages make these machines ideal for restrained quarries, as they do not interrupt the production process when a fixed or semi-moving shredder is rechecked or moved. They can also be used to grind materials used in the construction of infrastructure, roads, dams and underground cavities.

A mobile rough-grinding installation model

When considering the ability to use and select a mobile rough-grinding installation model, the following factors should be considered:

- Strength and abrasiveness of rocks: determines the type of crusher used;
- The size of the maximum power part: determines the required size of the breaker input;

The grain size composition of the food: determines the proportion of the volume in the feed stream which can be omitted in the first stage mill;

- Required capacity: Determines the type and size of the crusher, the feeder and the unloading conveyor.
- Required product size: determines the type and size of the crusher;
- Type and method of download: Determines the size and design of the receiving bunker.





Impact of complete mobile crushers with conveyor belts in operation and extraction process
The use of transport systems, consisting of mobile mobile crushers and conveyor belts, has a decisive influence on all technological processes and extraction processes.


The requirements for additional mineral processing do not depend on the type of crusher used for larger shredding: stationary or mobile. For a mobile crusher as for a stationary crusher, the ratio between the size of the drip hopper and the maximum size of the rock fed to the primary crushing operation is compelling. These proportions are the same for both types of crushers.

Mobile crushers and conveyor belts is particularly effective

Despite the high mobility of the Lokotrack and Lokolink conveyors, every movement is associated with the inevitable technological decommissioning of the entire complex. One of the real ways to reduce the number of movements of the entire complex is to increase the width of the processed input. This method is associated with the need to increase the number of exploding well pipelines. The system of mobile crushers and conveyor belts is particularly effective for the development of large shelves and a large number of wells working simultaneously. This last factor has a particularly important influence on the productivity of the digging machine and the load installed on the face.


As mentioned above, the relatively high mobility of the Lokotrack and Lokolink systems does not preclude effective work with excavators equipped with implements, such as front loaders and backhoe loaders. In addition, high performance wheel loaders with a bucket can also be effectively used to load coarse grinding crushers.


Currently, the load is carried on a rail with excavators in most large breakers. Small Models This type of machine is widely used in the industry because it offers obvious advantages in terms of specific productivity calculated per unit of work time for a number of factors:

- Easy control of excessive size in the chuck (because the operator sees the bucket filling process);
- a permanent overview of the grill conveyor, as the shovel is placed on the pile of stones. This helps to maintain the required loading of the grill material.

The size of the excavator can be selected to meet the capacity required to load the crusher.
In most cases, the use of excavators with equipment such as an excavator is considered to ensure the lowest possible loading costs.

When a crawler excavator is moved forward to a crawler excavator, its model is selected according to the working parameters of the machine: bucket capacity, radius and height of the unloading bucket, radio and height excavation. In normal operation, this usually results in the selection of a large bucket. Controlling the size of the crusher material loaded in the bucket and advancing the rock mass to the crusher is not as easy as using a backhoe.

The dredger works best to load the crusher evenly and finely into the hopper. With such packages, an excavator usually develops the best charging performance. The bucket "direct bucket" is at the same level as an excavator in terms of excavation work.

Wheel loaders have their own capacity

The wheel loader is inferior to both types of excavators in terms of the capacity and size of the excavation effort removed, as well as the oversize control of the crushing feed. Due to the ability of the loaders to direct the rocks into the bucket to the crusher silo, the use can increase the displacement capacity of a large crusher that is between 3 and 5 times. Hours 2-3 turns. , whereby the production time of the grinding complex is increased. The wheel loaders can also mix several rock surfaces (in the middle mode), whereby the optimum composition of the feed of the crusher can be achieved, while the maximum conveying distance of the rocks in the bucket of the loader (almost equivalent) is ensured). Crusher transfer) from 75 to 100 m.

When using a shovel loader mounted on the wheel, it is usually necessary to build a sloped ramp to load the standard shredder onto a line equipped with a grate feeder to allow the rock to pass from the bucket of the loader to the receiver unloaded. Funnel A boom of this type is usually cast from crushed rock and for half an hour of work, which is technically quite acceptable given the frequency of breaker movements. Higher productivity of the grinding complex requires the use of a plate loader to reduce the loading height and thus the cycle time of the loader.

Dump truck is a material transport but its capacity is limited

Typically, large standard caterpillar breakers have no receptacles to allow the direct discharge of rocks from the garbage truck. However, the possibility of such work organization can bring some benefits to the technology of mining production, especially at the beginning of a career development. This can occur, for example, when opening a new horizon in a quarry if there is sufficient space for the installation and operation of mobile crushers and conveyor belts.

It may also be technologically justified if the amount of rock mined in isolated parts of the quarry makes it economically impossible to dispose of waste into the quarry's transport system. In such situations, a large standard-way crusher may be fitted with an additional special bunker for the ground that can hold material dumped from the dump truck's trough.

Using conveyor belts greatly reduces material transportation costs

The indisputable advantage of road transport in a quarry is, as we know, its technological flexibility, as the original shredded material, with its help, can always be delivered from the sides, which are located somewhere in the mine. Of course this applies as long as there is a network of internal access roads on each side. The transport rate of the landfill of the mountainous mass of the quarry has no significant effect, for example when one or more garbage trucks stop working. These shutdowns can be easily eliminated at the expense of the reserve machines available in the quarry to keep the company's production capacity at least at a certain level.

Coarse shredding systems and conveyor belts are not that flexible. Mobile crushers for coarse crushing and moving conveyor belts are easy to move in the quarry, but the entire quarry transport system prevents a rapid change in the mode of operation of all transports. For this reason, mine planning is probably the only place where the use of coarse sanding systems and belt conveyors appears most critical.

The planning of the gradual progression of each horizon as well as a plan to place multiple sections of the career transport system has been developed over the years. At the same time he tries to minimize the frequency of movement of the conveyor belts.
General considerations on the efficiency of the crusher and the means of transport.

However, if the conditions for developing a particular domain do not meet the above requirements, there are ways to successfully implement the systems under consideration.


- Combine mobile equipment for large crushing and conveyor belts that work on two or three adjacent strips in a common system.
- The use of two or more parallel systems. This principle makes it possible to mix the starting material with different qualities that are extracted on different surfaces by expanding the theoretical productivity range of the opencast mines and improving the availability factor of the equipment.
- The possibility of uniting the mountain mass coming from camps or different faces through the energy system of the tunnel in one stream.

Recommendations

Mobile shredding systems and conveyor systems are characterized by certain limitations, mainly due to their operational flexibility, compared to transport in dump trucks. In many cases, however, these limitations do not play an important role or can be overcome by professional and innovative mining planning. With a carefully reviewed system application, the costs for mineral extraction can be significantly reduced. Therefore, it is very important for mining companies to determine the possibility of using the system at an early stage of the modernization of existing production or in a completely new project.

The residue from desulfurization and denitrification of exhaust gas treatment process with pyrolusite ore as absorbent is regarded as a potential source of iron and manganese. Manganese is also mined and processed with a cone crusher

Mangan has a long history

Manganese is a gray metal with a steel sheen that has a high hardness value. The extraction of manganese ore is of great importance, because it is used in almost all industries. The story of the appearance of Manganese can not be found in nature in its pure form. The main mineral in which it is contained is called pyrolusite. In ancient times it was used as a glass clarifier during cooking, as well as for dyeing fabrics. At the end of the 18th century, the Swedish chemists K. Scheele and Y. Gan discovered that the ore contained a metal in appearance resembling iron. He received the name "manganum", which was later transformed into "manganese".

Various uses of manganese

Manganese is an element found in plants and in all living organisms, including in humans.

• Its deficiency adversely affects the work of all human organs and systems.
• It is difficult to overestimate the importance of manganese, because it:
• Strengthens the nervous and cardiovascular systems;
• Normalizes the activity of the thyroid gland;
• Positive effect on reproductive function; regulates blood sugar levels;
• Speeds up the metabolism; maintains the necessary level of cholesterol in the blood;
• Strengthens the immune system.

Manganese can be used with alloys with other metals

Manganese is one of the most common elements in nature. Most often found in pyrolusite and iron ores (its hardness indicators are much higher than those of iron). Depending on the quantitative predominance of the metal, the deposits are called iron-manganese ore or manganese-iron.

The electronic formula of manganese: [Ar] 3d5 4s2. Formula of manganese in pyrolusite: MnO2xH2O. The widespread use of manganese due to its high chemical activity - it is able to react with a large number of elements, forming alloys. It also interacts well with oxygen, carbon, nitrogen and other non-metals. Being in a vacuum, the metal, when heated, is able to evaporate from any alloy, it dissolves in acids, reacts with water.

Industrial use of manganese

This metal is contained in almost all alloys, significantly improving their physical properties. The alloys obtained are durable, durable and resistant to corrosion. Manganese is added to them in combination with iron (ferroalloy). In the manufacture of steel metal manganese is indispensable - it acts as an alloying element, removes sulfur and oxygen from the alloy. The improved properties of metal-rolling allow it to be used in the production of wear-resistant equipment and various mechanisms in the military, construction, and aviation industries. Medical Applications In the medical industry, manganese is used in the form of potassium permanganate. Its aqueous solution (up to 5% manganese content) has antiseptic, hemostatic, adsorbing properties.

The solution has no contraindications, it is allowed even for the care of the umbilical wound of babies. But it is important to remember that a highly concentrated solution can cause severe burns.

Manganese ore mining methods. About 25 million tonnes of manganese ore are mined in the world every year. Work is carried out mainly in the open way, at least - underground. Quarry development is used if manganese ore deposits are not deeply buried underground. Depending on the area of ​​the field, dig pits of various sizes. The development of a quarry is carried out as follows: with the help of special equipment (most often bulldozers), the top layer of the earth is covered and removed, covering the deposits of the fossil; manganese ore is crushed; ore is loaded on dump trucks and sent to the plant for processing. after completion of the work, the quarry is again covered with a layer of earth, and reclamation takes place.

With the underground mining method, the main task is to lift the ore to the surface. The process consists in the following: horizontal (adits) or vertical passages (mines) are dug on the territory of the field; ore crushing is carried out underground with the help of equipment; the ore is loaded onto a conveyor and delivered to the surface. Underground method of extracting manganese ore is more expensive financially than open. It requires more modern equipment and workers. But ore mined under the ground is considered to be of higher quality, the investment pays off when it is sold.

However, with the open mining method, a large number of workers is not required, the equipment is simpler and more economical to use. The main advantages of open development are: high labor productivity; relative process safety (the likelihood of accidents is much less than in underground work). These benefits compensate for the negative impact of weather conditions and the need to cultivate a large area of land.

Manganese ore deposits

Depending on the complexity of the geological structure, form and size of ore, all deposits are divided into 3 types (established by the relevant order “On the classification of manganese ore reserves” of 11.12.2006): 1st group of difficulty - deposits geological structure; ore is represented by large layers in which manganese is evenly distributed; 2nd group of complexity - deposits with a complex geological structure; ore is represented by large strata in which manganese is unevenly distributed; 3rd group of complexity - deposits with a complex geological structure; The ore is represented by small layers, in which manganese is unevenly distributed, and its amount is extremely small.

Methods for extracting manganese from ore Most often, pure manganese is obtained from the ore by leaching. In the process, various chemical substances can be used, for example, sulfurous acid, ferrous sulfate, ammonium sulfate, etc. Their diversity is due to the fact that manganese has many compounds and modifications, each of which reacts differently in chemical reactions.

Despite the fact that there is no definite classification of methods for extracting metal from manganese ore, they all have a similar process: the ore is crushed to an extent that ensures the maximum reaction rate when interacting with various substances; the leaching process starts, as a result of which manganese takes the form of a solution; the resulting solution is free from impurities; when exposed to a reagent or when it is evaporated, manganese precipitates in pure form. With the help of chemical reagents, manganese can be extracted from sludge, low-grade ore, industrial waste. Where do you get manganese ores?

Lead Countries Today, the leader in the production of manganese ores is Russia, it has been at the forefront for several decades. In other states there are no explored large and rich deposits, their search is ongoing. The widespread use of manganese in the metallurgical industry has provided him with economic attractiveness. There are small deposits in the following countries: Bulgaria, Romania, China, Ukraine, Kazakhstan, Czech Republic, Germany, South Africa, Brazil, India, Australia, Japan, Indonesia, Mexico. In most of them are concentrated deposits of ore, not characterized by high quality. The needs of these countries are met by imported ore.

Countries with a high level of development of the metallurgical industry (USA, France, Belgium, etc.) are actively searching for large deposits in order to reduce imports. This will allow them to meet the internal needs of the state at the expense of their own resources. -

The increased interest of the United States is aimed at the extraction and further use of iron-manganese ore in the industry, which is concentrated on the bottom of the World Ocean. Mining of manganese ore in Russia Despite its leading position, Russia is experiencing significant problems in the field of manganese mining. The collapse of the Soviet Union was marked by the onset of an extreme degree of high quality metal deficiency. The main part of the work on its production was carried out at the fields, which are now territoriality owned by other states. This situation forced Russia to acquire high-quality manganese in foreign countries at import prices in order to cover the needs of the metallurgical industry. This situation persists to this day.

Industry prospects The metallurgical industry, which is rapidly gaining momentum in development around the world, is forcing countries to actively search for manganese ore deposits. Technologies are being improved every year, prospective areas are being developed. The main goal of any state is to reduce the volume of imports so that the satisfaction of domestic needs takes place mainly at the expense of its own resources.

Cone Stone crusher is suitable for processing lead

Lead has the advantages of low melting temperature and extreme form ability, which facilitates the assembly, shaping and assembly of lead articles. In addition, lead corrodes slowly and there are many examples of lead articles that have been around for centuries. Lead is relatively abundant. Lead concentrates can be easily recovered from the ore, and recovering metal from the concentrate does not require much energy. This is also reflected in a relatively low price compared to other non-ferrous metals. Lead can be used as a secondary raw material for lead-acid batteries, metal scrap and various consumer goods as well as for existing recycling loops, eg. As for steel, zinc and copper, to be recycled. moderate costs.

Lead is rarely used in its pure form as minor alloying additions greatly increase its strength. For applications where higher strengths are required, compounds such as lead-coated steel can be used.

The very high lead density lends itself to very different applications, such as sound, vibration and radiation protection as protection for users of computer screens and televisions. For this purpose, lead is used in metallic form or as a lead compound in lead glasses.

Some lead compounds have their own useful properties, especially in terms of color and the ability to form glass. As we can see, there is a potential market for lead ore in the future. The processing of lead ore is becoming more important.

One of the tin processing industries

The raw material is sent for ground grinding through the vibrating screen to the jaw crusher. The fractured material then passes into the cone crusher or impact crusher to further crush it in the secondary. The materials are then sent to the flotation machine via the conveyor belt. Depending on the properties of the materials, the appropriate chemical drugs are added to the flotation machine to separate the contaminants. After the chemical reaction, the materials are introduced into the concentrator where the necessary lead ore can be used.



The hydraulic cone crusher offers a better milling frequency and an eccentric distance, allowing a larger proportion of fine particles to be produced. And particles whose release is less than the closed line can reach 80%, which can significantly improve next processing capacity and reduce overall consumption. Now the hydraulic cone crusher has become the latest production to replace the spring cone crusher and the normal hydraulic cone crusher, and has also become the ideal equipment for large stone materials and crushing pits.

The HCS series hydraulic cone crusher uses computer optimization design to accelerate main shaft speed. The exclusive material exchange system of the baking plate makes it possible to quickly replace the components of the grinding chamber to meet the requirements of different sizes. The construction of the friction disc and the rotation of the eccentric shaft around the fixed cone, as well as the more meaningful "labyrinth seal" system, are the unique features of the HCS series, which offer more advantages as a function Simple, wider range of use, reliable and smooth operation compared to the spring cone crusher and conventional. It is the ideal equipment for the large rock quarry and mining.

Operation and properties.
First of all, the raw materials are regularly transported from the vibratory conveyor to the elementary grinding machine, after which the elementary products are transferred from the belt conveyor to the impact mill for secondary payment. The secondary products are separated by the vibrating screen according to their size. Products that do not meet the requirements are returned to the impact mill for further grinding.

The entire production line is highly automated and the finished product sizes are uniform, well-adjusted and can be adjusted with a high milling ratio, high processing capacity and low energy consumption. They are suitable for all types of products. Crushing station for the construction of roads and bridges.

The river of the stone grinding plant.
First, the raw materials are sent through the hopper in the vibratory conveyor, they are promoted uniformly and continuously in the jaw crusher. After being crushed by the jaw crusher, the materials are sent to the stone crusher, where they are produced by secondary shredding, creating a cubically shaped product. After the second crushing, the materials are sent to a vibrating screen, which separates the various products according to your needs. Although these particles have not reached the required fineness, they are returned to the impact mill for tertiary staking. Depending on the various technical requirements, use a suitable device model, research the article and develop the optimal behavior.
