The matrix is ​​generated in solids production and processing of coal. It is regarded as waste for thousands of years because it is of low calorific value and cannot burn directly. Therefore,the gangue has piled a mountain in many coal-producing regions. Storage of gangue is not only many of the land, after rain, it becomes acidic, affecting farmland and polluting groundwater.

Many people made gangue submit malls in coal mining areas. On the contrary, on the other person sees them as rich. Some company tried to burn them to produce hollow brick, or is mixed with coal to generate electricity. But all that matters is: smaller and gangue is not fully exploited.

Kefid Machinery has to develop and use the gangue. Now,our company manufactures the machines like this: mobile crushers, jaw crushers, impact crushers, cone crushers, raymond mill, ball mill, Vertical Mill etc. The machines can be used professionally to crush the gangue. They are used for many mines and power plants.

Jaw crusher is used in the mining, cement, chemical, railways and construction. Impact crusher can crush the materials with the lower length of 500mm and the compressive strength of less than 350 MPa. Materials can be coarse, medium and fine (gangue, granite, limestone, concrete, etc.). Impact crusher is widely used in hydroelectricity, highway, artificial aggregates, crushing and other industries.

Cone crusher is used for grinding of raw materials in metallurgy, construction,road building, chemical industry and silicate. He crushed all ores and rocks with medium hardness or above. It is for fine grinding and ultra-fine hardrock, ore, slag, refractory and others.

Impact crusher is widely used in metallic and nonmetallic minerals, cement, refractory,abrasives, glass raw materials, construction aggregates, artificial sand and variety of metallurgical slag. Particularly for hard and extra hard or corrosive materials, it is more superior to other crushers.
