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.
What is a Hammer Mill Used For? A hammer mill is a particle size reduction machine. After the material is fed into the machine, the hammer mill uses its continual high-speed hammer to grind and crush the material into smaller pieces. Mills can be primary, secondary, or tertiary crushers, allowing for a wide variety of applications.
