The grinding mechanism in the Vertimill is also different from that of traditional mills. While traditional mills rely on impact grinding, where balls are lifted and dropped to crush particles, the Vertimill design is based on attrition grinding. In this method, the grinding media remains in contact with the material, applying continuous …
