Aug 1 2015— 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
View MoreCoal Mills are used to pulverize and dry to coal before it is blown into the power plant furnace Operation The coal is feed into the coal mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill where the grinding table and some heavy rollers pulverizes the coal to particles
