What Is A Jaw Crusher

θ: Nip angle. One of the most important parameters is the angle between the two jaws, which is referred to as the nip angle. The nip angle is the angle at which the material, that passes through the inlet to be between the jaws can be gripped by the jaws without slipping. This angle depends on the size, hardness and frangibility of the material.
