The rolls are operating with 5 m/s or more and shear and compression forces crush the material between the roll in the gap. The crushed material is released through the crusher base frame onto a discharge conveyor. The floating roll enables the crusher to release tramp metal and adjust the gap by the hydraulic supported gap setting system.Web

A crusher is a machine that uses mechanical energy to break blocks of stone, concrete, or other building materials into smaller blocks of a specific grain size. They are particularly used in the mining industry to reduce the size of ore blocks and facilitate their processing. Crushers are designed to receive blocks of a maximum size.Web
