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.
What is angle of nip in roll crusher? 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. Usually, the nip angle is between 20° and 30° but in some large roll crushers it is up to 40°.
the nip angle when the crusher feed size is 10 cm, 4. the coefficient of friction between roll and gypsum particles. 6.5. At a nip angle of 30°, an approximate relation between peripheral speed ν P (m/min), diameter of rolls D (cm) and sieve size d (cm) through which 80% of ore passes is given by the relation ν P = 1.8 D − 40 d + 128

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
The 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 ...
