The working principle of the vertical roller mill (also called vertical mill or raw mill) is mainly based on the dispersion, crushing, and grinding process of materials on the grinding disc. Specifically:

 

The material falls into the middle of the grinding disc through the feeding pipe, and the motor drives the reducer to drive the grinding disc to rotate. The grinding disc rotates at a constant speed and uses centrifugal force to evenly disperse and flatten the material outward to form a material bed of a certain thickness. In this process, the material is crushed by the crushing action of multiple grinding rollers on the grinding disc. As the material is continuously ground, the material particles with qualified fineness are blown up by the airflow of the blower and screened by the classifier. The material with too coarse particle size will fall back into the main machine for re-grinding, while the material with the fineness that meets the specification will enter the dust collector with the airflow for collection, and finally be discharged through the powder outlet as a finished product.
