Coal gangue, a solid waste discharged during coal mining and coal washing, can partially or completely replace clay components to produce ordinary cement. The coal gangue crushed by the coal gangue crusher has been rapidly developed and applied in various industries due to its good characteristics, mainly used in coal gangue fired hollow bricks.
Coal gangue is a kind of black gray rock with low carbon content and harder than coal, which is associated with coal seam in the process of coal formation, and has low calorific value. The resource utilization of coal gangue has become the focus of the comprehensive utilization of coal gangue, and also the raw material for the additive required by the large-scale new brick and tile factory to produce environmental bricks. The main uses of coal gangue are divided into:
1. It can be used for power generation, mainly by using the mixed combustion of washed coal and washed gangue, and using medium coal, coal slime and coal gangue for power generation.
2. It can be used to manufacture building materials, mainly brick making materials. The combustibles of coal gangue are used to save coal. The hollow bricks are sintered. The coal gangue bricks produced from coal gangue have high strength, large thermal resistance and good sound insulation. It can reduce the thickness of building walls, reduce the amount of bricks used and also have a relatively clean appearance.
3. It can be used to recover coal and pyrite. The recovered coal can be used as fuel for power boilers, waste washing can be used as building materials, and pyrite can be used as chemical raw materials.
Coal gangue pulverizing equipment pulverizer is a kind of processing equipment for fine powder and ultra-fine powder. It has its unique characteristics in high fineness grinding, and is suitable for coal gangue, marble, limestone, barite, bentonite, phosphate rock, rectorite, etc, especially, the demand for fine powder in the grinding market is increasing, which intensifies the development of ultra-fine powder equipment such as coal gangue pulverizer.
SMMVIK Machinery mill has the advantages of long service life of vulnerable parts, high safety and reliability, high product fineness and environmental protection. It is a relatively new upgraded fine powder mill product. The particle size of the material after crushing meets the requirements of users and the output is higher. It greatly improves the requirements of crushing high moisture materials, and has more prominent advantages than the traditional coal gangue crusher.
