Working principle of ultra-fine pulverizer: When working, the material to be pulverized is added into the machine from the feeding hopper on the side of the hood, and the grinding roller device suspended on the main plum frame of the main machine revolves around the vertical axis and rotates itself. Due to the centrifugal force during rotation, the grinding roller swings outward and presses against the grinding ring, so that the blade shovel the material between the grinding roller and the grinding ring, and the purpose of pulverizing the material is achieved by rolling rolling of the grinding roller. Wind selection process: After the material is ground, the fan blows the wind into the main casing, blows up the powder, and sorts it through the analyzer placed above the grinding chamber. The coarse and coarse material falls into the grinding chamber and re-grinds. The degree of compliance with the wind enters the cyclone collector, and is collected and discharged through the powder outlet, which is the finished product. The wind flow is returned to the fan by the return air pipe at the upper end of the large cyclone collector. The air path is circulated and flows under the negative pressure state. The increased air volume of the circulating air path is discharged through the exhaust pipe between the fan and the main engine, and enters the small cyclone collection. The device is cleaned. Superfine pulverizer is widely used in barite, calcite, potassium feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass, High-fine powder processing of various materials such as thermal insulation materials with a Mohs hardness of not more than 6.5 and a non-inflammable and explosive mineral, chemical, construction and other industries with a humidity of 6% or less, and any adjustment of the finished product size within the range of 20-325 mesh .
