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

6. TYPES OF COAL PULVERIZER • Tube or ball mills: Low-speed machines that grind the coal with steel balls in a rotating horizontal cylinder. If the diameter of the cylinder is greater than the length of the cylinder, the mill is called a ball mill. If the length of the cylinder is greater than the diameter of the cylinder, it is called a tube mill.

avoid accidents which could be costly in terms of coal lost, emissions of pollutants, and, ultimately, risk to the health and safety of those involved in the industry. New techniques and technologies have been developed to predict coal heating behaviour and to analyse gas emitted from coal which is oxidising (an initial indication of self-heating).

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.
