Coal Mill MachineA machine that crushes coal lumps into coal powder, a process in which coal is broken down and its specific surface area continuously increases. Coal mills can be categorized intoLow-speed Coal Grinding Mill、Medium-speed coal millAndHigh-speed Coal Mill MachineThree types, each coal mill has its strengths. Customers can choose the appropriate coal mill for production based on their actual needs.

Operating Principle

Raw coal is fed into the feeding device of the mill, with a temperature ofAround 300℃ hot air also enters the feeding unit through the air intake pipe. A specially designed lifting plate in the drying chamber lifts the raw coal, enabling intense heat exchange and drying. The dried coal pieces then pass through a double-layered separator with lifting plates into the pulverizing chamber. The pulverizing chamber is equipped with grinding media (steel balls), where the coal pieces are crushed and milled into coal powder. As the coal pieces are crushed, a dedicated blower extracts the milled coal powder and gases through the mill's discharge unit. Coarser particles are returned to the pulverizing chamber via the discharge unit's return spiral for further grinding.
