  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
