Marcy® Double Roll Crushers are used in intermediate size reduction of medium hard to hard materials such as rock or ore and can bridge the gap between laboratory and production outputs. Models with 3,000lb per hour (1,361kg) or 8,000lb per hour (3,629kg) capacity reduce most materials from 0.5in (13mm) feed size to minus No. 10 (2mm).

THE DOUBLE-ROLL CRUSHER AiODEL The model proposed by Austin et al. [1, 2] for breakage in an open circuit double-roll crusher is based on the assumption that if the particle size range is split into geometric size intervals (i-e. the sieve series) the breakage of each size interval occurs independently of other sizes. That is, if f; and p; …
