Improving Coal Pulverizer Performance and Reliability

achieved as the smaller coal particles are ground through attrition against each other and the grinding face. Vertical Roller Mills This mill uses hydraulically loaded vertical rollers resembling large tires to pulverize raw coal fed down onto a rotating table. As the table rotates, the raw coal is pulverized as it passes underneath the rollers.

Pulverizer - Wikipedia

Similar to the ring and ball mill, the vertical spindle roller mill uses large "tires" to crush the coal. These mills are usually found in utility plants. Raw coal is gravity-fed through a central feed pipe to the grinding table where it flows outwardly by centrifugal action and is ground between the rollers and table.
