Coal Processing Coal Preparation Coal Handling RPM

Coal processing involves crushing, screening and beneficiation. Processing is where coal is converted from run-of-mine (ROM) coal to a product that meets the customer's requirements. Mined coal can include lumps. Crushing to a manageable size is required. Coal crushing can include a two stage process, dependent on deposit size.
