or segments. Pulverization occurs when coal particles are squeezed together with other coal particles under enormous pressure. The footprint and the pressure of the grinding elements are what govern coal pulverization. For example, the amount of contact area beneath the tires on an MPS mill is limited to three small footprints beneath the

The BTM is a lowspeed 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

Explanation: The pulverization or crushing action in ball and race mill takes between the two moving surfaces called balls and races. The rolling action happens between these two. Then the coal passes between the rotating elements time and again until it has been pulverized to the desired degree of fineness.
