Introduction Vertical raw mill is a type of industrial equipment used to crush or grind materials into small particles.Vertical roller 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 virgin supplies of these materials.
The latest installation was a WPU type gear unit for another vertical raw mill in 2005.
