Abstract: As the market demands efficient, highly flexible and high capacity plants for cement production, it was time to develop an innovative drive concept to cope with these demands: the world's first vertical roller mill with driven rollers. With this concept, it is the rollers of the vertical roller mill that are driven, not as is usually the case the grinding table.

Firstly, VRMs are more energyefficient, requiring less power to grind the same amount of material. This is because the grinding rollers and the rotating table work together to crush the material, reducing the need for additional grinding media. Secondly, VRMs have a lower noise level, making them more suitable for use in urban areas.
