As a common ultra-fine vertical mill equipment, the high efficiency mill adopts advanced structure at home and abroad, and is updated on the basis of ordinary high productivity mill. The equipment has higher efficiency, lower power consumption, smaller coverage area and less one-time investment than ball mill. As the grinding roller and the grinding ring are tightly controlled by the centrifugal force, when the grinding roller and the grinding ring are worn to a certain thickness, they do not affect the output quality and fineness of the finished product. The replacement cycle of grinding roller and grinding ring is long, so as to eliminate the shortcoming of short replacement time of wearing parts. The wind selected air circulation fan, mill barrel, cyclone separator and fan's working condition, so the high productivity mill has less dust, clean workshop and better environment than high speed centrifugal mill.

High productivity mill mainly includes main engine, analyzer, fan, cyclone separator, cyclone separator and air duct. Among them, the main engine is spiral case, scraper, rack, grinding roller, grinding ring and shell. High productivity mill is widely used to grind ultrafine powders in barite, calcite, potassium feldspar, talcum, marble, limestone, dolomite, fluorite, lime, active white soil, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass, heat preservation material and other moth hardness less than 9.3, humidity of 6 Less than 280 kinds of non flammable and explosive materials are widely used in mines, chemical industry, construction and other industries. The grain size of high productivity mill can change from 80 to 425 materials, and some materials can be as high as 600.

When the high productivity mill is working, the abrasive material will be added to the machine from the engine hood side hopper, which is attached to the roller device on the main frame of the mainframe, and the mill rotates around the vertical axis. At the same time, the machine is rotating at the same time, because of the rotating centrifugal force, the grinding roller swings outward and pressed on the grinding ring, making the scraper shovel material, grinding the roller and grinding ring through the mill roll to achieve the smashing material, and the high efficiency mill is updated to get a better working condition.
