Sand production and mining

The sandblaster is suitable for grinding various minerals and rocks of medium hardness such as iron ore, non-ferrous metal minerals, silicon carbide, bauxite, quartz sand, corundum, perlite, basalt and other hard materials.

1. Types of sand.

Type of sand according to its use

Sand is the most varied in composition and origin:

Natural sand is the result of the destruction and grinding of several rocks, which led to the formation of a special homogeneous substance from small grains.
Natural sand means according to its origin that its origin and its composition can be alluvial, flood, marine, lacustrine, wind. The sandy beaches created by their activities, such as water and streams, are rounder.
Heavy artificial sand is a substance consisting of grains of different sizes and fineness, which are obtained and produced by intentionally detaching or grinding several solid rocks.

When talking about building land, there are also several types of sand, namely, that construction workers classify it according to the territorial origin and the treatment that it has received:

River sand, sand at construction, which is obtained directly at the edge of the channels of several rivers, is characterized by the purity of the sand compared to the remaining sand and, if no other impurities are present, deposits of clay and small stones minor impurities
The quarry is washed, the sand is extracted, the quarries are excavated and the raw materials of the quarry are crushed, washed and cleaned with various clay deposits and impurities.
Artificial sand is sown. This sand also occurs in a quarry, but is not washed but dried and filtered through various contaminants and sediments. Produce asphalt
According to legislation, the structure of the sand corresponds to the definition of this material as a granular inorganic material of a certain size and fineness of the grains whose sand forms after the destruction of several solid rocks, for example rocks. through the development of various deposits, eg gravel,

2. Equipment for sand.

Every production is always a specific technological process

This always applies to equipment used to manufacture a particular material, raw material or product.
The equipment for sand production is very individual for the entire production of a piece of equipment. Such a large complex for the production and conversion of multiple sands is in various types of industries, such as. In the construction, metallurgy, mining and glass industries and in many other industries. The complex for the production of sand itself consists of such parts:

Vibratory feeder;
Break the jaw
Drum mill;
Vibrating screen;
carrier

Another type of sand production equipment that is part of the crushing and screening complex has the following configuration:

Break the jaw.
Vibration screens;
Washing of gravel;
conveyor;
Cabinets

The production of sand by direct application of all previous equipment is based on the typical grinding of the rock to the required size and on the composition of the total substance obtained.

3. Sand production and mining technology.

A variety of sand has a different purpose and meaning in construction or in another industry

When it comes to quartz sand, sand is very important in modern construction because sand is one of the most important constituents of all mixtures, solutions and substances used in buildings of various types and types. Quartz sand plays an important role in the production of cement and other binders, solutions and materials.

It is used in all constructions such as artificial sand and other natural sands with natural natural quartz origin. The most important and important difference between artificial sand and natural sand is that artificial sand is obtained by grinding a variety of rocks. At the same time, its composition is completely different from natural sand.

The method of making sand is quite expensive, as the desired amount of material is difficult to estimate. At the same time it is very profitable if everything converges and natural sand is not enough.

The technology of producing sand, or rather dry quartz sand, always involves several rather complex stages. The steps of sand production are as follows:
