Jaw crushers work by using two hard-faced heavy plates, or jaws, to crush large particles. The final sample size can be determined by adjusting the distance between the two jaws. Gilson offers a selection of standard to heavy-duty laboratory jaw crushers, each with unique features and capabilities, to accommodate a wide range of capacities and

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.Crushers may be used to reduce the size, 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 (as in rock ore), so that pieces of different composition can be differentiated.
