Vertical mill can be used to produce grinding and crushing materials, mainly including calcite, limestone, pyrophyllite, barite, fluorite, glaze, slag inclusion, wollastonite, kaolin, vermiculite, mica, feldspar, brucite, spore, potash slag, garnet, quartz, ilmenite, magnesium oxide, magnesium hydroxide, dolomite and other industries.

The motor drives the grinding disc to rotate through the reducer. The material falls into the center of the grinding plate from the feed port, and the hot air enters the mill from the air inlet. Under the action of centrifugal force, the material moves to the edge of the grinding plate. When passing through the annular groove on the grinding plate, it is crushed by the grinding roller. The crushed material is carried by the high-speed airflow at the air ring at the edge of the grinding plate, and the large particles fall directly on the grinding plate for regrinding When the materials in the air flow pass through the classifier, under the action of the rotating rotor, the coarse powder falls on the grinding plate for regrinding, and the qualified fine powder goes out of the mill together with the air flow, and is collected in the powder collecting device, which is the product. The material containing moisture is dried in contact with hot gas to reach the required moisture content of the product. In the circulation process, a small amount of excess gas and light impurities in the finished product are collected by the branch vacuum cleaner in the system for low-grade product treatment, thus forming a quite scientific and advanced process.

Low operation cost:high grinding efficiency, low power consumption, 40-50% power consumption compared with other grinding equipment such as ball mill Raymond. It has the advantages of low abrasion, special material for roller sleeve and liner, long service life, reduced metal pollution and operation cost. It can be equipped with external circulation device, which can further reduce power consumption and improve product accuracy.
Low construction cost:compared with the ball mill system, the floor area of the vertical mill can be reduced by about 50%, and the construction cost can be reduced by about 70%. Due to the collection of crushing, drying, grinding, grading transportation in_ The system is simple, so the construction cost is low.
Easy and reliable operation:equipped with automatic control device, remote control can be realized, and the operation is simple and easy. It is equipped with a device to prevent direct contact between the roller sleeve and the grinding plate lining plate, which will not cause destructive and violent vibration.
Convenient maintenance:through the overhaul of the oil cylinder, the boom can be replaced in a short time.
Less pollution:small vibration, low noise, system in negative pressure operation, no dust overflow.
Stable product quality:the material stays in the mill for a short time, which is easy to detect and control the particle size and chemical composition of the product. This machine is equipped with a high-precision classifier to grade products from 325 mesh to 2000 mesh. The classification accuracy is high, the cutting grain is accurate, and the product quality is stable.
