Vertical roller mill is a popular pulverized coal mill in recent years. Working Principle. The working principle of vertical mill is as follows: the material is fed into the mill through the inlet on the top center of the mill and falls on the grinding plate, and the grinding rollers which are driven by the rotation of the grinding plate will crush the material.

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.

Introduction. This article concerns itself with vertical grinding mills used for coal pulverization only (coal pulverizers), although vertical grinding mills can -and are- used for other purposes..
