### Angle Of Nip In The Roll Crusher

Roll Crushers ScienceDirect the nip angle when the crusher feed size is 10 cm, 4 the coefficient of friction between roll and gypsum particles 65 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 = 18 D − 40 d + 128Calculation Of Nip Angle Jaw.
