The number of roller mills employed in the cement industry shows an upward trend [142]. Roller mills have a lower specific energy consumption than tumbling mills, and require less space per unit and capacity at substantial lower investment costs. Roller mills are developed to work as airswept grinding mills.

Vertical mills comprise 24 conical rollers which are hydraulically pressed onto a horizontal rotating grinding table. The roller axis is inclined at 15o to the table and, as axes of rollers and table do not intersect in the plane of the table. the relative motion involves both rolling and sliding which enhances comminution.

Vertical roller mills. The VRM is a commonly known grinding unit in the cement industry. The VRM sizes range from approx. 2 to 6 m in table diameter, and depending on the VRM size, the feed material will vary between pebble sized rocks in small VRMs and Ø150 mm fragments in large final product will typically be classified/separated at 12% + 90 μm.
