The Quest for Nanotechnology and the Evolution of Wet and ...
· Feed material size for ball mills is usually less than 1 in., and they are effective to produce a particle size range of 5500µ, in some cases as fine as 1µ, but this is usually the limit. When mills are emptied, the slurry is discharged through a grate which retains the grinding media in the mill while allowing the product to pass.

How Ball Mill Ore Feed Size Affects Tonnage Capacity
· Hard ore Work Index 16 = 100,000/65,000 = kwh/t. For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tons ...
