The matrix model was used to simulated vertical roller mills in cement clinker and coal grinding lines. The pressure breakage function, B, was determined from the laboratory test data with a hammer device. The results showed that materials are crushed in more than one stage under the vertical roller mill.

MVR vertical mill with conventional drive: economical solution for small to medium output rates. For the preparation of cement raw material, cement, and granulated blast-furnace slag with small to medium output rates, the MVR mill with conventional drive is the right choice. This mill type is by the way the core piece of our modular ready2grind ...
