Jaw crushers and roll crushers fracture large particles between surfaces, and impactors can either strike material with a blow bar or project it so that the material strikes a surface. Impactors and jaw crushers create sharperedged particles, while mill types that apply compression and shear forces tend to produce particles more rounded in shape.

Impact crushing crushing grinding method. Shear crushing is accomplished by breaking along or across lines of cleavage. It is possible, when required, for a crusher to use a combination of two or three of these principles. The selection or sizing of a crusher is much helped by measuring the rock's hardness during engineering.

A crusher is a machine that reduces large rocks into smaller rocks, gravel, or rock dust. Crushers are mainly used in the mining and construction industries, where they are used to break down very large rocks and boulders into smaller pieces. Crushers are also commonly used for jobs like breaking up asphalt for roadwork or demolition projects.

As the name suggests, this type of mill consists of two jaws, one fixed and one moving. The moving jaw compresses material against the fixed jaw using tear, shear, and impact forces to cause material to fracture. Jaw crushers are used on a range of industrial materials: Stone and gravel; Ceramic and glass; Construction aggregates; Recyclables
