The cone crusher is a modified gyratory crusher, and accordingly many of the same terms including gape, set, and throw, apply. The essential difference is that the shorter spindle of the cone crusher is not suspended, as in the gyratory, but is supported in a curved, universal bearing below the gyratory head or cone ( Figure 6.8 ).

The high pressure of HPGR’s “bed-breakage” creates micro-cracks in the ore, promoting improved mineral recovery at coarser size fractions. This means less leaching acid is required and percolation periods are shortened, reducing costs and maximising recovery in less time. In the diamond industry, the HPGR acts as a selective grinder
