Our products sell well all over the world, and have advanced technology in the field of crushing sand grinding powder.
Throughput was limited by a higher proportion of competent skarn and diorite in the mill feed the lower throughput scenarios were recorded as the baseline maximum. Additionally recent ore characterisation test work data was also used to validate the low historical throughputs using Ausencos comminution benchmarking tool Ausgrind.
