Mill Speed - an overview | ScienceDirect Topics
Medium-speed mills are smaller than low-speed units and are generally of the vertical spindle construction. The speed of the grinding section of these mills is usually 75–225 rpm. They operate on the principles of crushing and attrition. Pulverization takes place between two surfaces, one rolling on top of the other.

Coal Mills
The counter pressure reduces the noise generated by the mill and is adjustable depending on the coal properties and required coal fineness. During operation, both pressures are adjusted proportionately to the feeder speed by means of pressure control valves to achieve an optimized grinding force characteristic throughout the mill load range.
