The capacity, or throughput, of a ball mill is directly linked to particle size of the ball mill discharge. For example, it takes approximately 3 times as long to achieve 200 mesh grind as it does to achieve 65 mesh grind. Establishing a commercial liberation size is critical when designing and engineering your grinding circuit.
It seems certain, however, that the ballmill will crush to 200 mesh a considerably greater tonnage when the proper classification is provided. Since in previous tests the mill has crushed 7½ T. per hr. from ¼ in. to 200 mesh, it seems possible that it will crush at least 8 T. per hr. from 48 to 200 mesh. ...

The bond work index for a meshofgrind of 200 mesh for a rock consisting mainly of quartz is kWh/ton. How much power in kW is needed to reduce the material in a wetgrinding ball mill from an 80% passing size of 1100 µm to an 80% passing size of 80 µm at a capacity of 10 ton/hr? ANSWER: Could you please show the solution?
