The BTM is a low-speed mill that primarily grinds coal by impact and attrition. The VRM is a medium- speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed

It may be mentioned here that roller table mills in power stations operate with F sp between 0.10 and 0.50 N/mm 2. The test mill runs with a circumferential speed of 0.036 m/s. This is comparable with that one of the Hardgrove tester (0.08 m/s), however, much slower than the velocity in technical coal mills of about 3 to 5 m/s.
