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.

Dynamic classifiers allow instant adjustment to provide wide flexibility of operation and size specifications. The vertical blade classifier (VBC) is the Bradley standard classifier for efficient classification of fine ground powders. The BLVT reduces the recirculating load in the mill system which results in higher throughput and less wear.
