Raw coal is conveyed from the storehouse by a belt conveyer. Then it is lifted to the entrance level of a vertical cylindrical mill by a bucket elevator, and an electromagnet is used to remove iron objects from the raw coal. The raw coal is pulverized in the vertical cylindrical mill, and the pulverized coal is lifted to a powder separator by

Coal is currently beneficiated predominantly in wet condition. The conventional methods for processing of coarse coal like heavy media bath, jigging etc. utilizes water. In the near future, coal resource and water resource is going to have a reverse distribution thus posing several hurdles to wet beneficiation technologies in coal cleaning.

Mill Feeders: Feeders for coal mill are generally installed directly under hoppers with rod gate in between. The feeders are generally 2 to 3 m long and discharge on to conveyor or feeding chute to mill. For coal mill feeding, table feeders, belt feeders, chain feeders and weigh feeders have been used.
