Coal gangue is a solid waste discharged in the process of coal mining and coal washing, including the gangue in the roadway excavation process, the gangue extracted from the roof, bottom plate and interlayer in the mining process, and the selected gangue in the coal washing process, but it still has good application value.
How much is a coal gangue crusher?
Coal gangue is a dark gray rock with a lower carbon content and harder than coal in the coal-forming process, with a hardness of 3-7 on the Mohs scale. Combined with the characteristics of the material, jaw crusher, hammer crusher, and roll crusher are all good choices for crushing coal gangue, which can be considered from the raw material particle size, output, budget, finished product, site, etc.
Jaw crushers and hammer crushers are small, medium and large, so they range from tens of thousands to millions. Roll crushers are small and medium-sized, small in size, light in weight and low in cost, ranging from 10,000 yuan to 450,000 yuan. Of course, the specific ** depends on the choice of equipment type and model, output, manufacturer and so on. In addition to paying attention to its own **, it is also necessary to look at its internal quality. At the same time, the material selection, workmanship, products and services of various manufacturers are not complete.
What about the market after coal gangue crushing?
After coal gangue is crushed, it can be used for power generation, preparation of aluminum-based chemical products, preparation of foam concrete from coal, manufacture of building materials, etc. In addition, it can also be used to produce low calorific value gas, make ceramics, make soil amendments, or pave roads, fill land, fill soil.
Because the main components of coal gangue are Al2O3, SiO2, and other trace rare elements (gallium, vanadium, titanium, cobalt), it is inexpensive and more cost-effective than other mining masterbatches. After crushing, its particle size is uniform, it is cubic, the needle content is low, the adhesion is good, and the pressure is resistant. The fineness modulus can be artificially controlled through the production process, and the production can be organized according to the user's requirements.
