Roll Crusher
The nip angle is affected by the distance between the rolls. The nip angle is defined as the angle that is tangent to the roll surface at the points of contact between the rolls and the particle. It depends on the surface characteristics of the rolls. Usually, the nip angle is between 20° and 30° but in some large roll crushers it is up to 40°.

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.
