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°.
The Jaw Crusher was first introduced by Eli Whitney Blake in 1858 as a double-toggle Jaw Crusher.

The definition of fines and if minimizing fines generation is beneficial; ... Some materials are considered too hard for Roll Crushers and may need to be tackled by a Jaw, Impactor or Gyratory crusher. ... This angle of nip ensures that the crusher has the ability to grab the feed material and pull it into the crushing zone without delay.
The angle of nip, the angle between the jaws, is usually about 30°. Because the crushing action is intermittent, the loading on the machine is uneven and the crusher therefore incorporates a heavy flywheel. The power requirements of the crusher depend upon the size and capacity. The Volume Surface Mean Diameter Ds:
The nip angle is the angle formed by the V. An eccentric shaft passes through the top of the jaw stock and pivots around a toggle plate at the lower half of the jaw stock to produce an elliptical motion. This geometry converts the eccentric shaft's rotary motion into a fore and aft motion at the bottom of the jaw plate, resulting in the ...
