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.
Nip angle. Larger diameter rolls reduce the nip angle between the rolls and allow the rolls to more efficiently grab the material and pull it down through the rolls.

If not "starvation" fed, rolls are choke-crushers, ore grinding on ore. Unless rolls of very large diameter are used, the angle of nip limits reduction ratio, so that a flow-line may …
The development and acceptance of the technology for hard rock ores occurred later during the mid-1990s for iron ore and the mid-2000s for large copper concentrators and gold plants due to the development of studded roller surfaces which reduced the wear (Lane et al., 2009).
Figure 1 is the geometry of a double roll crusher with a spherical particle about to enter the crushing zone of a roll crusher and is about to be nipped [4], [5]. For rolls that have equal radii and length, tangents drawn at the point of contact of the particle and the two rolls meet to form the nip angle
