Roll Crushers ScienceDirect

Jan 01, 2016· the nip angle when the crusher feed size is10 cm,4. the coefficient of friction between roll and gypsum particles. 6.5. At a nip angle of30°, 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

Diameter of Rolls for a Roll Crusher for the Given feed

The following formula relates the coefficient of friction (m), radius of rolls (r), radius of product (d), and radius of feed (R): cos a = (r + d) / (r + R) à 1. where a is related to the coefficient of friction by the relation, m = tan a. Angle of nip= 2a. We have, m = 0.29. Therefore, a = tan-1 (0.29) = 16.17 o. And we have, d = 0.5 cm; R = 1.5 cm
