This article outlines best practices and precautions to ensure th
The bowl mill uses a motor and gear system to rotate a bowl at 40-65 rpm, grinding coal into a fine powder. Hot air enters to dry the coal while heavier debris falls out of the bowl. A grinding roller assembly applies pressure and can be adjusted, while vanes inside separate finer particles from coarser ones that are returned for further grinding.

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
