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.
Grinding increases the cross sectional area of the coal and allows it to dry quicker whilst also making it easier to ignite. Grinding is often referred to as ' size reduction '. …

The grinding media size should be 2–10 mm. They are usually made of zircon-based compounds, ceramic materials, or aluminum oxide in order to reduce wear. 50–80% of milling chamber volume is filled by grinding media, and the media are fluidized when impeller rotation reaches an optimum value.
The diagram does not show a coarse coal grinding mill which makes it possible to obtain 6–13 mm particles. As the figure shows, the process of obtaining WCF is complex, and the diagram itself contains many components which means that the technological line usually takes up a lot of space.
