Crusher an overview ScienceDirect Topics
The gyratory crusher has capacities starting from 1200 to above 5000 t/h. To have a feed opening corresponding to that of a jaw crusher, the primary gyratory crusher must be much taller and heavier. Therefore, primary gyratories require quite a massive foundation. The cone crusher is a modified gyratory crusher.The gyratory crusher shown in Figure 2.6 employs a crushing head, in the form of a truncated cone, mounted on a shaft, the upper end of which is held in a flexible bearing, whilst the lower end is driven eccentrically so as to describe a circle. The crushing action takes place round the whole of the cone and, since the maximum movement is at the Gyratory Crusher an overview ScienceDirect Topics

Comminution and classification technologies of iron ore
The gyratory crusher has capacities starting from 1200 t/h to above 5000 t/h. To have a feed opening corresponding to that of a jaw crusher, the primary gyratory crusher must be much taller and heavier. Therefore, primary gyratories require quite a massive foundation. Application of more efficient grinding technologies developed in The gyratory crusher is located at the bottom of the rock box. Material is crushed between the rotating crushing cone and the fixed, tapered crushing throat. The Rockbreaker is mounted in-line with the upper support of the rotating cone, called the spider. This provides superior maneuverability of the Rockbreaker within the gyratory throat.Rockbreaker-Applications Creighton Rock Drill Ltd.
