Ball Mills work by employing various types of media (either steel, ceramic or lead balls) to crush the material in the barrel. To use the Mill, the material to be ground is loaded into the barrel which contains grinding media. As the barrel rotates, the material is caught between the individual grinding media balls which mix and crush the ...
The rod mill was needed to reduce feed size to the ball mill because crushing plant output was normally coarser than 80% passing 10,000 microns. Such feed causes power inefficiency if fed directly to a ball mill.
If there is too much water in the mill the water will wash the larger rock deeper into the mill separating the rods even further. This, of course, does not allow the fine material to come into contact with the surface of the rods so they can he ground. Remember what goes into a mill must come out at the same rate.
