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 ...

Read More2017-4-19 The angle of nip in gyratory crushers has definite limitations. In the older straight element crushing chamber, the angle ranges from 20" to 24". On large primary crushers, using curved or nonchoking concaves and where gravity is of marked aid to nip with the large pieces at the mouth. the angle runs from 25" to 30°.
Read More2019-6-3 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 short ton required to reduce the material to 80% passing 100 microns.
Read MoreThe nip angles ranged from 4° to 12° and decreased significantly when the proportion of brittle material increased. Nip angles were also calculated using the widely used Johanson model. However, wall friction measurement on serrated roll surfaces could be impractical. The Johanson model-derived nip angles could differ by 3°-8° just by ...
