combination of impact and attrition crushing. In this type of crushing first coal is break due to impact and further scrub between two hard surfaces to get desired coal size. Some crushers are work only on principle of impact crushing. Generally these crushers are used before final crushers. The output size of coal affects the performance of CHP.

What is a crusher? A crusher is a machine that is designed to reduce large rocks into smaller rocks, gravel, or rock dust. Crushers may be used to reduce the size of materials, or change the form of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials so that pieces of different composition can be easy for next step separation.
