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.The quadropol® concept for coal or pet coke grinding, with adapted table speed and high efficiency separator sepol®, ensures a safety mill operation and serves reliable the kiln burning process.
