2015-8-1  Coal mills or pulverizers play a very essential part in the coal-fired power production system. 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.
