The coal is broken down to particles of less than 125 millimetres in a crusher and then washed, screened, rinsed and dewatered.

After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site.

The plant cleans and processes coal to remove dirt, rock, ash, sulfur, increasing the heating value of the coal.

During this coal processing, the used industrial equipment can be called coal processing equipments.
