While renewable energy has undergone wide and rapid deployment, coal is still expected to be the main source of fuel for producing base load power in the near future. This is because coal reserves are expected to last for the next century and its cost is still relatively cheap. However, the emissions from coal combustion are a major environmental concern. Coal mill employed at coal fired power plant. In coal fired energy plant, coal mill is employed to grind, pulverize and dry coal ahead of the coal is transmitted the boiler. The coal is feed into the coal mill by way of a inlet pipe so that the roller coal mill such as Raymond mill and vertical mill can pulverize the coal into particles.
