· This can be applied to crushing, milling, and other forms of comminution equipment. It is the angle which the two plate surface frictions exceed the mechanical advantage of the particle geometry to expel itself. It is the point where the two comminution surface taper (nip) angles are either self locking or self releasing.
The nip angle is the angle at which the material, that passes through the crusher inlet to be crushed between the jaws can be gripped by the jaws without slipping. This angle depends on the size, hardness and frangibility of the material. It cannot be selected as too large or too small. The nip angle in primary crushers is lower than in ...

2019-6-3 · Handbook of Crushing Glossary of Terms Angle of Nip — The angle formed between the moving surface of a crusher roll or jaw plate and the stationary plate surface at which point the material will be pinched. Angle varies with machine size and material lump size. Bond Work Index (BWI) — Kilowatt hour (kWh) per
2019-5-13 · The closed-side setting of a jaw crusher helps determine the nip angle within a chamber, typically 19 to 23 degrees. Too large of an angle causes boiling in the crushing chamber. This is where the jaw plates cannot grip onto the rock, and it keeps slipping up and down, avoiding being crushed. The nip angle gets flatter as the machine is set ...
2016-1-1 · 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°.
