Case Study Improving Crusher and Mill Throughput and ...

2012-8-22  unweathered pegmatite ore. Ore production was set to double and the existing rates, the primary crusher was under-utilised. Which meant, that at future rates, the primary crusher would be operating very close to its rated capacity. Therefore, there is benefit in optimising the muckpile fragmentation to improve crusher performance. Mining Issues
