Xinxiang Great WallCoal Mill MachineIt is a horizontal coal grinding equipment specifically designed for powdered coal grinding, a process where coal is crushed and its specific surface area continuously increases, serving as an essential auxiliary equipment for coal powder furnaces.
Structural Principle
Raw coal is fed into the feed device of the mill, along with hot air at approximately 300°C, which enters through the air intake pipe.
2. The drying storage is equipped with special lifting plates to lift the raw coal, allowing for intense heat exchange here and achieving drying. The dried coal pieces then enter the grinding storage through double-layered separator plates with lifting plates.
3. The storage bin is equipped with grinding media (steel balls), where coal lumps are crushed and ground into coal powder.
4. As the coal lumps are crushed, a dedicated induced draft fan extracts the powdered coal and gases together from the mill's discharge unit. Coarser particles are returned to the mill storage through the discharge unit's return spiral for further grinding.
