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 …

The gyratory crusher by virtue of its annular discharge opening is an effective slab breaker. This faculty, coupled with the fact that its receiving openings are especially well suited for admitting slabby feed, give it a very definite advantage over the jaw crusher in the handling of such material.

Curved plates are sometimes used to prevent choking near the crusher discharge, which can occur if fines are present in the feed. The lower end of the swing jaw is concave, while the lower half of the fixed jaw is convex, allowing for a gradual reduction in size as the material nears the exit, minimizing the chance of packing.
