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

MoreFigure 6.4 is a typical set-up where ores crushed in primary and secondary crushers are further reduced in size by a rough roll crusher in an open circuit followed by finer size reduction in a closed circuit by a roll crusher. Such circuits are chosen as the feed size to standard roll crushers normally does not exceed 50 mm.
