Roller mills accomplish size reduction through a combination of forces and design features. If the rolls rotate at the same speed, compression is the primary force used. If the rolls rotate at different speeds, shearing and compression are the primary forces used.
Frame: A frame, made of wood or metal, must hold all the other components solidly and securely. Its construction can be as simple as a foursided frame with room to install the other components. A flat, even surface to mount the rollers is essential, as the rollers must meet evenly to function properly.

Roller mill. Roller mills accomplish size reduction through a combination of forces and design features. If the rolls rotate at the same speed, compression is the primary force used. If the rolls rotate at different speeds, shearing and compression are the primary forces used. If the rolls are grooved, a tearing or grinding component is introduced.
Vertical roller mill is an advanced equipment concentrates on processing coal, cement, slag, nonmetallic mines and etc. It integrates crushing, drying, grinding, grading, and conveying in one unit. It is a highyield and lowconsumption grinding mill developed by Hongcheng.
Loesche developed the 4roller coal grinding mill with four tried and tested modules for throughputs over 150 t/h. The development was first realised in 1970 for grinding mills in the cement industry. This number of rollers also enables operation with only one pair of rollers to increase control response availability and flexibility.
