Types of Crushers Explained: Everything You Need to Know

In roll crushers, the material is pulled between two counter-rotating rolls which exert a shear force on it. The material breaks and reduces in size due to this force. This kind of crushing works better for materials that have a layered or flat structure because the shear forces can easily split the material along the weak planes.
