Crushed stone and gravel of solid rocks

After many years’ research, Mastour company has developed an advanced vertical shaft impact crusher, which can be used together with other machinery as a complete sand making flow. This design racks a leading role in the same industry

Fields of mining granite and other dense rock myriad of the former Soviet space. Those who are still not closed, or just under construction, capable of supplying companies for the production of building materials for many years. One of the most essential elements for building work can be considered as crushed stone and gravel of solid rocks.
Based on the fact that there are standards for road metal and gravel, rocks, those instances that have a relative density of the particles from 2 to 3 grams per cubic centimeter, are used exclusively as a filler for concrete mixtures and as material for road and other works building character. What concerns rubble and gravel, which does not apply the standard, its application is limited to use as ballast for railway tracks and of course, as a decorative gravel.
Granite rubble, as well as other rocks, starting with mine explosions solid granite slabs. After that huge chunks of granite transported to the crushing plant, where with the help of special equipment all parts and sorted into fractions. Thus, the smallest fraction of a granite screenings, which is used exclusively for decorative purposes. All subsequent fractions used in the manufacture and filling of building materials. The largest is usually used very rarely. Their use is limited to decorative features, such as decorating the fountains, pools and artificial lakes.
Before the rubble and gravel get into the building materials, conducted a series of studies, which determine the structure of rocks, their strength, flakiness, frost resistance, bulk density, and of course radionuclide diagnosis to identify the class of ionizing radiation. Only after all results are known, rubble and gravel can be sorted by application. To date, rubble and gravel can be bought in DIY stores, or directly at the mining complex.
