— How many rollers are used in a rolling mill? The quantity of rollers employed in a rolling mill varies based on the specific application and the desired final product. Rolling mills can have two to several dozen rollers arranged in a specific configuration. Common roller configurations include two-high, three-high, four-high, and cluster mills.

The feeder (A) deposits raw material into the base of the Roller Mill (B) at a rate determined by pressure variations with the grinding mill. Plows located ahead of each roller direct the material upward and between the grinding rolls and the heavy alloy steel bull ring, where it is ground to the specified size.
