Grinding Mills: Ball Mill & Rod Mill Design & Parts

Common types of grinding mills include Ball Mills and Rod Mills. This includes all rotating mills with heavy grinding media loads. This article focuses on ball and rod mills excluding SAG and AG mills. Although their concepts are very similar, they are not discussed here. Photographs of a glass ended laboratory ball mill show action of ball mass within the mill. The action of other grinding

Overview of milling techniques for improving the

The critical speed may be estimated based on the following relationship : Critical speed (rpm) = 54 / R ft where R ft is the diameter of the vessel measured in feet. As the rotational speed of the vessel decreases, attrition plays a more dominant role in particle size reduction relative to impaction and compression, yielding finer particles at the expense of longer processing times.
