Comparison of roller stone crusher with others

Aggregates are made of different types of materials. The word "aggregate" in itself means a collection of different things, in this case stone, gravel, gravel, sand and slag. These materials often begin in the form of larger or larger rocks or compressed sediment layers, and some very heavy machinery require forming work to convert them into usable aggregates. After they have been crushed into small pieces with the help of crushing units, they can be used for road construction, buildings, platforms or other purposes like coal fot energy.

1. Coal Specification.

Coal processing often uses roller stone crusher

Coal is an important source of energy. This makes paper an important raw material in metallurgy and the chemical industry. The recovered raw coal is too big. The coal is not treated and crushes the environment of efficiency and contamination. To use the coal more efficiently and less contaminated, it must be crushed and reduced to a reduced size. For a grain size of 5 to 20 mm for the gas stove, a grain size of 8 to 25 mm for the steam locomotive, a grain size of 10 to 20 mm for the industrial furnace. Coal-fired power plants require coal with a grain size of 5 to 20 mm.



Coal Mill Instruction

The coal milling machine consists of many types of mills. This coal mill is not used alone. They form a complete crushing plant with conveyor belt and vibrating screen. In the power plant, the coal gasification and the treatment of purified coal, the grinding process is the first step and the essential. The conveyor belt conveys natural coal evenly into the jaw crusher. After grinding, it passes into the impact crusher or the cone crusher for fine grinding. Final is eliminated by the projection machine.

In order to use coal more efficiently, efficiently and effectively, the coal has to be processed and ground in various sizes, grain size from 0 to 25 mm for the coal furnace, 25 to 8 mm for the steam locomotive, 25 to 6 mm For the industry, ovens and coal power stations need 0 up to 25 mm carbon. Therefore, coal processing in coal processing plant includes coal grinding and coal milling.

SBM coal machine
SBM has been a manufacturer of crushers and mills in China for 30 years. At any time we supply all types of crushers and mills for the quarry, the coal industry, the cement, ore and concrete industries.

Application of the coal crusher.
The boiler of the station is a boiler that supplies steam to the turbine generator of the thermal power plant, including the equipment of the boiler and its accessories. The fuel is burned in the boiler and releases heat energy and heat transfer through the metal wall of the boiler water to a certain pressure and temperature of superheated steam and then steam therein. Turbine, turbine-driven generators. The total thermal power generation capacity is around 70%, of which 80% is in China. Therefore, the boiler and its role in terms of energy consumption or the development of the economy have a significant impact. The fuel in the boilers of the plant consists mainly of coal. The design of the coal grinding plant is therefore the main grinding plant of the thermal power plant for grinding coal.

2. Hammers of hydraulic crusher.

One stone crusher that uses hammer

In the construction industry, materials must always be broken. Therefore, you must use a jaw crusher such as hydraulic breaker, hydraulic breaker and demolition robot. The Grabengraben requires regular hydraulic equipment such as hydraulic hammers and hydraulic hammers to break up a large mass of stone or stone. To demolish buildings or level roads, we also need demolition equipment such as a two-roll crusher and a demolition robot.

On this page you will find our shredders. We mainly manufacture hydraulic hammers, hydraulic crushers, demolition robots and boom systems, as well as parts for demolition equipment. We have years of experience in manufacturing hydraulic equipment, so we know how to make high quality demolition equipment. In order to continue to offer the highest quality and most advanced equipment, we have analyzed the hydraulic equipment of other manufacturers and incorporated elements to improve their own hydraulic equipment. In this way we are confident to offer a hydraulic impact crusher, a demolition robot, a hydraulic crusher and a high quality boom system.

3. Crushing and grinding.

Crushing and grinding is often used for rocky tillage

The crusher is the exclusive composition of particles larger than 3 mm of the total emission rate of 50% or more of the crusher. The operation is often interrupted during feeding and probing in the size of broken, cracked and stingy grains. The road under the refractive power of the crusher can be roughly divided into two categories: (1) crusher; (2) rectifier. General switches for larger coarse grain materials, usually larger than 8 mm. Its structure is characterized by a certain distance between the fragments, they do not touch. The crusher can be divided into coarse crushers, crushers and fine crushers. In general, the grinders, the handling of smaller materials and the size of the product are good, up to 0.074 mm or more detailed. The structure of a broken part (or medium) is in contact, the medium used consists of steel balls, steel rods such as gravel or a mineral block. However, some machines also have crushing and grinding effects, such as grinding and conditioning of mineral materials from the upper limit of 350 to 400 mm, the product fineness being up to about 40% to 200%.



Road under the crusher from structural features to the classification, generally divided into six categories.

(1) Jaw crusher (Tigermund). The fragmentation function is to periodically move the jaw to the firm pressure of the jaw block in the folder where the ore is being ground.

(2) cone crusher. Pepita inside and outside the two cones between the fixed outer cone, the inner cone for the eccentric oscillation, the shirt in which the ore breaks or collapses.

(3) roll crusher. The mineral blocks in the two opposite rotating rolls are caught in a circle, mainly by the successive grinding effect, but also in the grinding function, the surface of the broken toothed roll is divided.

(4) vertical breaker. Nugget by the rapid rotation of the moving parts of the keystrokes were compressed. In this category the case can be divided into: sand making machine, hammer crusher; Crusher with impact crusher cage.

(5) grinding machine. The ore and abrasive were milled from the impact and abrasive media into the rotating cylinder by the milling media (steel balls, steel bars, gravel blocks or minerals).

(6) Other types of broken crushers.

A roller mill: Crush the material by rotating rollers

B, plate: vertical or horizontal axis of the disc, which rotates like the broken parts.

C, centrifugal mill. High-speed turned parts and media production capacity to complete the squeezing force.

D. Vibration rectifier. Made with a high-frequency vibration wave, so that the carrier and the materials to be produced touch and produce a grinding effect

Different types of crusher specifications, different uses. Currently selected crusher-jaw crusher broken or multi-stage plant; the standard cone crusher rotates; Small type with short cone crusher. Grind with a grinder, finely ground with a ball mill.
