In the comminution process there are usually a few steps in the breaking down of ore, and this usually starts with a first stage or primary crushing. Primary crushing is done before the ore can go through a final crush or grinding process to get the gold out. This primary crushing can be by means of a jaw crusher, a gyratory.

Honig (1937), however, could find no significant difference between the results of pressure crushing and those of impact by falling weight, using cement mortar and brick cubes. Bond (1946) regarded impact strength as a better guide to grinding resistance in gyratory and ball mills than standard crushing strength tests.
