coal mills speed

To summarize the coal mill controls they may be divided basically into two major categories 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. here means the temperature and fineness of the PF.

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.
