Technological Process

Gangue’s hardness is low, it pollutes environment badly, therefore, technology-based machine should be preferential concerned to protect environment. Vipeak gangue powder grinding machine, gangue crusher has many advantages like environmental protection and energy saving, Vipeak gangue grinding mill is applied for processing gangue, barite, limestone, ceramic, slag and other material whose Moh's hardness is less than 9.3. This machine is suitable for mining, metallurgy, chemical engineering, building material and many industries material fine powder making, final product size is adjustable. The gangue grinder is constituted by separator, rollers, grinding table, pressure device, reducer, electromotor, machine shell,etc. According to position of conditioning tower and dust catcher, there are two different layout plans: triple draught fan system and double draught fan system. Rotoclone collector could collect final product, negative pressure of system and gas flow of collector would be reduced.

Application Fields

Gangue is mainly applied in gangue cement producing, lightweight aggregate of concrete producing, and refractory brick material producing. In addition, it could be used in coal recycle process, coal and coal gangue power generation, crystallization of aluminum chloride and sodium silicate production and precious rare metal extraction process, it could be used as fertilizer. Meanwhile, gangue could replace clay as raw material of brick making to save fertile farmland, and coal resource could be saved. Gangue could replace clay to be material of cement and lightweight aggregate, and be used to produce low-heat value gas, ceramic, soil conditioner, or applied for road paving, underground filling, ground filling. Grass can also be planted on the hillock and gangue to beautify the environment.
