For GC2 ore, the stirred mill produced significant finer product than the ball mill. Similar trend was observed in the GHB ore test result. Only in the test with SMT ore sample, did the two mills generate virtually similar products, but the stirred mill only consumed 73% of the energy used by the ball mill.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
