The ore is sent into a singlecylinder hydraulic cone crusher for the secondary crushing. Thereafter, the gold ore is transferred to a multicylinder hydraulic cone crusher, where the ore is crushed further into finer material. From there, the crushed gold ore is sent to a ball mill, evenly as it passes through a vibrating screen for grinding.

A description of the Chilean mill gold recovery process written in 1857. The most approved mode of crushing the rock, and of separating the gold, is either by stampers, or the improved Chilian mill. Except in the mode of crushing, the modus operandi is nearly the same in both. The first is by heavy stampers, weighing from two to six hundred ...

The ore from the feeder next passes over a roll or vibrating grizzly. For the small 150 to 200 ton per day mill this opening can be 2 inches. This will allow the wet sticky fines to pass through the grizzly. A high pressure water spray over the grizzly often aids in the subsequent jaw crusher operation.
