Clirik, a leading manufacturer of industrial mills, has announced the successful operation of its CLUM Series Ultra Fine Vertical Roller Mill in India, where it has been used to grind calcite to a fineness of 15 microns with a remarkable throughput of several tons per hour. This achievement marks a significant milestone in the ultra fine powder processing industry, demonstrating Clirik’s commitment to innovation and efficiency.

The CLUM Series Ultra Fine Vertical Roller Mill is designed to meet the growing demands of the market for high-capacity ultrafine powder processing. Integrating functions such as grinding, classifying, conveying, secondary classifying, and packing into one machine, the CLUM mill is capable of producing powder with a fineness ranging from 400 to 3000 mesh. Its ability to process calcite to such a fine degree while maintaining high output is a testament to Clirik’s engineering prowess.

The mill’s main structures include the motor, reduction gear, grinding rollers, grinding plate, pressure-applying device, classifier, mill body, oil station, and electrical system. The grinding roller, a key component for crushing and grinding materials, operates passively due to friction force when in contact with the materials. The grinding plate, driven by the reduction gear, is the area where the grinding process takes place. The pressure-applying device controls the gap between the grinding roller and plate, maintaining the roller pressure. The classifier, a multi-rotor classifier, utilizes centrifugal force to separate fine powder during the continuous process, making it a highly efficient and energy-saving powder separating device.

The CLUM mill’s working principle involves the rotation of the grinding plate by the main motor via the reduction gear, with high-pressure air entering the mill interior. Materials fall onto the center of the grinding plate and move towards its fringe due to centrifugal force. The grinding roller crushes and grinds the materials directly, while the fine particles form a material bed where inter-particle crushing occurs until they are ground into fine powder. The fine powder is then carried away by the air flow and separated by the classifier, with the final product collected and discharged as finished powder by the powder collector.
