Our latest throat designs are compatible with sub-optimal metrology (Oval mills) with tight tolerances. The EnFloTech high-performance rotating throat range reduces unwanted rejecting, lowers peak velocities, lowers mill dP and guarantees at least a 10% increase in mill throughput. Another major advantage is the alleviation of wear to mill components …
2. The hot air is used for transportation of the recirculating coal within the mill and also for transporting the coal from the pulverizer to the furnace. As the coal is continuously reduced in size, the smaller/lighter particles are swept from the bowl by the hot air. Hot air (and cool tempering air) is provided by the primary air fans.

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
