Recently, Clirik announced that its CLUM series ultra-fine vertical grinding mill has been successfully used in ultra-fine grinding of limestone in India, achieving a breakthrough in the fineness of the finished product reaching 2500 mesh (about 63 microns). This achievement not only improved the processing quality of ultra-fine powder, but also broke the industry bottleneck of low ultra-fine powder processing capacity.

Clirik CLUM series ultra-fine vertical grinding mill is an ultra-fine grinding equipment designed for non-metallic ores. It is suitable for brittle materials with a hardness lower than Mohs hardness 6, such as limestone, calcite, marble, etc. The equipment adopts an advanced central control system and is widely used in paper-making, plastics, rubber, artificial stone, paint and coating industries. It is a professional equipment for producing fillers for large paper mills and calcium carbonate for coatings.

In terms of working principle, the CLUM series ultra-fine vertical grinding mill drives the grinding disc through the motor. The material is pushed to the edge of the grinding disc under the action of centrifugal force and ground into fine powder in the grinding area between the grinding roller and the grinding disc. The ground material continues to move to the edge of the grinding disc until it overflows the grinding disc. Through the airflow ring on the edge of the grinding disc, the airflow sends these overflowing materials to the powder separator for classification. The coarse powder that does not meet the fineness requirements will fall back to the grinding disc for re-grinding, while the qualified fine powder will be collected in the dust collector and finally sent to the finished product warehouse for storage and packaging through the conveying system.

Clirik CLUM series ultra-fine vertical grinding mills are favored by the market for their high efficiency, strong drying capacity, versatility, low noise and low dust emission. The equipment can not only save 20-30% of energy consumption, but also process raw materials with up to 15% humidity, realizing the integrated operation of crushing, drying, grinding, separation and conveying.

The successful application in India not only demonstrated the excellent performance of Clirik CLUM series ultra-fine vertical grinding mills in processing high-hardness limestone, but also provided a new solution for the global ultra-fine powder processing industry. Through this efficient grinding technology, Clirik has helped customers achieve high production capacity and high quality in ultra-fine powder processing, and promoted technological progress and industrial upgrading in related industries.
