crushing is to feed some coarse ores directly to wet or dry semiautogenous or autogenous grinding mills (using larger pieces of the ore to grind/mill the smaller pieces), then to pebble or ball mills. Ideally, the liberated particles of iron minerals and barren gangue should be removed from the grinding circuits as soon as they are formed, with ...

These mills use balltype grinders inside chambers. They offer extremely high efficiency levels when grinding rocks containing gold, with minimal friction and relatively low energy consumption. If you are handling large quantities of ore and want to keep overheads to a minimum, a ball mill will make perfect sense.
