Ultrafine mill is a special ultrafine powder production equipment,which is producd by our company with a combination of foreign advanced production technology , the device has a series of advantages, such as the structure is so strong in the production line in the relatively stable operation, With a closed system and make the device's environmental performance is better, which are to help the community to become a more popular low-cost environmentally friendly production equipment.
Structure of Ultrafine mill
Superfine grinding is mainly made up of grinding roll and millstone. It is the two important component of the mill, and its abrasion resistance and toughness are quite good. As we all know, two of the mills now use electricity as the power source, and the motor drives the reducer to drive the mill system to work.
- [Feed granularity]: 10-20mm
- [Production capacity]: 4-12T/h
- [Application]: widely used in paint, paper making, pigments, rubber, plastics, fillers, cosmetics, chemicals and other industries
- [Material]:Widely used in paints, paper, pigments, rubber, plastics, fillers, cosmetics, chemicals and other industries. Ultrafine grinding is mainly suitable for processing a Mohs hardness of < 9 level non flammable and explosive brittle materials, such as coal, mica, talc, graphite, quartz, fluorite, calcite, dolomite, limestone, kaolin, bentonite, barite, feldspar, bauxite, coal gangue.
Closed circuit grinding technology of Ultrafine Mill
The grinding process is divided into two kinds of closed circuit and open circuit. It has been proved by practice that the advantage of open circuit grinding system is that the process is simple and the material is finished after grinding. However, it should be noted that the material in the mill flow rate is slow, long residence time, it is likely to cause excessive grinding of materials, the particle size of the finished product is unfavorable.
Therefore, we advocate and promote the use of closed-circuit grinding system, by adding ultra-fine grinding powder selecting equipment, timely fine powder has been milled from outside the mill, so as to effectively avoid the problems of open circuit grinding system. At the same time, the speed of the material flow in the closed circuit is accelerated, and the grinding bodies of each silo undertake the crushing or grinding tasks respectively, so the productivity of the equipment can be increased by 40%.
Improvement of structure of Ultrafine Mill
The improvement of the structure of the ultrafine mill is mainly reflected in the setting of the length of the bin in the mill, the form of the liner, the type of the compartment, the hole rate and the arrangement way. These parameters are adjusted to meet the requirements of the new cement standard Material fineness and particle size requirements. The state-of-the-art team achieves the balance of various squeezing forces in the mill by appropriately shortening the length of the coarse grinding bin and increasing the length of the fine grinding bin.
