Coal mills grind the coal into fine powder, and the primary air entering the mill dries and drives the coal into the power plant furnace for combustion. Mills can be a bottleneck for the power generation process. Overall plant performance and reliability is highly influenced by the mill downtime. If there is less or no pulverized coal for ...Web

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 speedWeb
