Coal gangue is solid waste discharged during the coal mining process and coal washing process. It is a black-gray rock with low carbon content and harder than coal that is associated with coal seams during the coal formation process. It includes excavation gangue during roadway excavation, gangue extracted from floor and interlayer, and gangue picked out during coal washing. Its main components are Al2O3 and SiO2, and it also contains varying amounts of Fe2O3 and trace rare elements (gallium, vanadium, titanium, cobalt).
In recent years, coal gangue has been regarded as a huge amount of solid waste, and as a resource that can be used, it has been widely studied and applied in the fields of building materials and chemicals. In the case of energy shortage, mining machinery and equipment manufacturers pay more and more attention to energy-saving research and development and production. FIGHTER attaches great importance to the upgrading of mining machinery and equipment. Its European coarse grinding mill is a processing equipment for fine powder and ultrafine powder. It is suitable for coal gangue, marble, limestone, barite, etc. European coarse grinding mill has the advantages of long service life of wearing parts, high safety and reliability, high product fineness, simple mechanical structure, compactness, portability and environmental protection. The European coarse grinding mill is mainly composed of rotor, bearing iron, casing, and grate bars and other components. FIGHTER European coarse grinding mill is professionally used for the comprehensive utilization of coal gangue with excellent quality.
