Coal Vertical Roller Mill (VRM) is an air swept, medium-speed, vertical pulverizer with integral classifier. It pulverizes coal by applying hydraulically-loaded grinding pressure through three grinding roller onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal grindability and desired product fineness.

effect of the mass flowrate of coal and air, classifier geometry, and the opening of the spiral guide vanes on the coal classification efficiency [5, 6]. It is worth to mention that the optimum quality of classification for coals such as lignite is achieved when 70% of coal particles exiting the classifier is smaller than 75 μm [7, 8] .
The HEP Classifier has the ability to balance the air/coal ratio in each coal pipe served by a classifier, with externally adjustable guide vanes at the outlet to each coal pipe. These guide vanes are designed and positioned to either capture or divert the pulverized coal from entering the outlet. Field experience has demonstrated that ...
