The working principle of the CR series vertical grinding mill involves the relative movement of the grinding disc and rollers to crush, shear, and grind materials into fine powder. Materials enter the mill from the top and fall onto the center of the grinding disc. After being crushed by the grinding disc and rollers, the materials are carried by airflow into the classifier for grading. Qualified fine powder is collected, while coarse powder is returned to the grinding disc for further grinding. The specific working process is as follows:

1. Feeding: Materials enter the mill through the feed inlet and land on the center of the grinding disc.
2. Crushing: The grinding disc rotates, driving the rollers to crush and grind the materials.
3. Grading: The ground materials are carried by airflow into the classifier, where they are graded based on particle size.
4. Collection: Qualified fine powder is collected by the collection device, while coarse powder is returned to the grinding disc for further grinding.
