SBM Group CLUM ultra-fine vertical powder grinding mill as the crystallization of mid-end advanced technology has become the latest product leading the trend of mill machines in the world. It is widely used in non-flammable and explosive brittle materials, such as calcium carbonate，carbon black, mica, talc, graphite, quartz, fluorite, calcite, limestone, dolomite, coal and other fine powder and ultra-fine powder processing. Its extremely fine product fineness has become the iconic advantage of this series of equipment.
CLUM ultra-fine vertical powder grinding mill
Discharge fineness: 150-3000 mesh
Feed size: <15 mm
Output: 1-20 T/H
Range of application: Calcium Carbonate, Limestone, Gypsum, Kaolin, Dolomite, Barite, Feldspar…
Product features: It has high grinding efficiency, low energy consumption, uniform particle shape, narrow particle size distribution, good fluidity, and strong product adaptability.
The particle size of the CLUM ultra-fine vertical powder grinding mill can reach 150-3000 mesh, the fineness of the maximum up to 3500 mesh. An ordinary powder separator can not effectively select the powder in this fineness range. After the introduction of technology and field tests, SBM CLUM ultra-fine powder mill using multiple powder separator configuration, in the efficiency of powder selection and powder particle size distribution has obtained a breakthrough technical improvement. As the third generation of the efficient separator series, multi-head classifier has a breakthrough improvement in powder efficiency and powder fineness.
The multi-head classifier adopts the arrangement of multiple small-diameter cage separators, the impeller adopts horizontal structure, and all of them are controlled by frequency converter. Each impeller is equipped with a speed measuring device, through the feedback signal to accurately control the impeller speed, to ensure the stability of the powder fineness. When working, the motor drives the impeller to rotate through the shaft. Due to the suction effect of the external fan, the ground powder will go to the impeller with the wind. Because the wind from the impeller clearance flow, the powder will be through the impeller analysis and selection to go through the powder separator. Such a large powder is not easy to enter the impeller is thrown to the inner cylinder wall down to the top bulk tray, re-grinding.
According to the engineer of SBM Group mill, the multi-head classifier produced by German technology can effectively improve the precision of powder selection, the fineness of the product can be adjusted between 325 mesh and 3000 mesh, and the fineness of the product can reach d97≤5μm at one time.
At present, the CLUM ultra-fine vertical powder grinding mill is the company’s largest model of ultra-fine milling, and also the biggest micro-milling in the industry. Compared with other models, it was CLUM1736 Ultra-fine grinding not only uses multi-head separator, and each rotor can frequency control, the fineness of grinding products can be achieved in the selected range, but does not need to go through the secondary wind separation classification, there is no material.
According to the customer service department, a company producing ultrafine powder in Guangxi, China purchased two sets of CLUM ultrafine mill from Shanghai Shibang for processing calcium carbonate. Day operation 11 hours, the person in charge of the company said: “I have been engaged in the ultrafine grinding industry for more than ten years. Shanghai Shibang products are very good. Our finished products supplied to more than 60 manufacturers, widely used in paper, paint, paint, PVC and other industries, have been widely recognized by customers.” And this customer purchased grinding equipment from us again this year and added a new calcium carbonate powder grinding production line.
