The necessary press force is created by a hydraulic—pneumatic system which works like a spring. The movable roller is actuated towards the static roller with the help of a hydraulic cylinder to grind the clinkers fed from the vertical chute/hopper over the rollers. The roller comprises of a steel shaft and a mounted tire made of "bainite".

The Vertical Roller Mill works like a cyclone to grind the limestone into fine, evenlysized particles. The feed is ground on a horizontal table, with hot air rising from below, lifting the smallest particles. The finest particles go through a separator to the top mill compartment, while heavier particles return to the table for more grinding.
