efficient vertical roller mills (VRMs) led to their replacement. Initially, this focused on grinding coal and the cement raw materials, with the adoption of vertical roller mills for cement product grinding – with its finer grinding requirements – com-ing more recently, in the late 1990s. The main reason for
We have supplied vertical roller mills (VRM) for raw, coal, slag and cement grinding for several decades. The vertical roller mill is well known in the cement and power plant industries as the preferred mill for grinding of raw materials. It is increasingly used as a solution for efficient grinding.
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
By changing the conventional 4-roller design to the 5-roller raw mill, a 10% down-sizing was achieved, and by changing the conventional 4-roller cement mill to the new 6-roller mill, a 20% down-sizing was achieved while maintaining the same grinding capacity in both cases. As just described, by changing to smaller, modular

Vertical raw mill is a type of industrial equipment used to crush or grind materials into small particles. Vertical raw mills are widely used in the concrete and mining fields, and are also used to process gypsum. These units can process both raw and recycled materials, while helping to reduce waste and preserve supplies of these materials.
Ulf Weller, Senior Design Engineer, MAAG Gear AG Rocco Amato, Head of Mill Gear Engineering, MAAG Gear AG Drive trains of vertical roller mills are usually equipped with heavy duty gearboxes with a horizontal input shaft and a vertical output shaft. Increasing mill sizes bring the existing gearbox concepts to their limits, however.
