### Determination of the Nip Angle in Roller Compactors With ...

The calculated nip angles were validated against those obtained from physical measurements during actual roll compaction. These nip angles were in agreement for various powder formulations containing plastic and brittle materials. 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 ...

01/01/2016 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°.

For smaller angles of nip (finer feeds), the roll speed can be increased, thereby increasing the capacity. Peripheral speeds vary between about 1 m s −1 for small rolls, up to about 15 m s −1 for the largest sizes of 1,800 mm diameter upwards. The value of the coefficient of friction between a particle and moving rolls can be calculated from: (6.5) μ k = [1 + 1.12 v 1 + 6 v] μ. where µ ...
