Rose and Hill (1967) considered crusher capacity by determining the amount of time and distance a particle takes between two jaw plates. Particles in the A-B zone discharges at the next reverse movement of the jaw. The maximum size of a particle dropping out of the crusher d max is determined by the open size setting (L max).

Gyratory crushers are principally used in surface-crushing plants. The gyratory crusher (Figure 6.5) consists essentially of a long spindle, carrying a hard steel conical grinding element, the head, seated in an eccentric sleeve.The spindle is suspended from a "spider" and, as it rotates, normally between 85 and 150 rpm, it sweeps out a conical path within …
