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

It can be said that coal as a solid fuel is far more benign as biomass. As a consequence, power stations have started to use modern online measurement and control systems to measure the two phase flow inside PF (pulverised fuel) piping to bring light to the darkness of these problems. There are three main areas to be looked at: The burners ...
