Two vs three-stage crushing - Australian Mining

2021-8-24  A two-stage crushing system is best employed when tonnages are relatively low, the coal and rock is soft and capital expenditure is limited. Two-stage crushing systems operate best when a grizzly is installed on top of the receival hopper, or when the size of the ROM coal will not exceed 800 millimetres top size. This allows the feeder breaker to easily crush to a nominal 150–200 millimetres,
