13.1.1.2 Medium-speed mill. 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.
