The ball mill work index laboratory test is conducted by grinding an ore sample prepared to 100% passing mm (6 mesh) to product size in the range of 45150 µm (325100 mesh), thus determining the ball mill work index (Wi B or BWi). The work index calculations across a narrow size range are conducted using the appropriate laboratory work ...

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 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

The water can wash away the fine particles in time to avoid overgrinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%10% lower than that of a dry ball mill. The grinding particle size is fine and uniform.
