Hence, to hold the slip within reasonable limits, the angle of nip must be decreased as the speed is increased. The feed size being a fixed quantity, for any given application, the only way to decrease nip angle is to increase the roll diameter.

Chapter 6 - Roll Crushers

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°.
