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.
