Working Principle of Clirik ultrafine grinding equipment . When the grinding mill is at work, all the grinding rollers are rolling in the ring, and the materials are driven to the edge of the turnplate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed, crushed and grinded by the rollers.
The Ultrafine Mill is a highly efficient mechanical mill which has been developed for the production of ultra-fine powders with tightly controlled particle size distributions. It will simultaneously grind, dry, and chemically modify the surface of powders and splits. Grinding capacities range from 100 kilograms per hour to 1 tonnes per hour.
