Performance Benefits of Milling Equipment


     Hongxing brand Raymond mill is widely used for barite, calcite, feldspar, talc, marble, limestone, dolomite, fluorite, lime, active clay, active carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass, thermal insulating material and other material of which the Mohs hardness is less than 9.3 degree and the humidity is under 6%. Additionally, it is used for ultra-fine powder making and processing of more than 280 kinds of materials used in non-inflammable mineral, chemistry, construction and other industries. R type Raymond grinder can arbitrarily adjust the final product granularity range of 80-325 mesh, and part of particle size can achieve 600 mesh to the maximum. 
Working Principle of grinder mill :
     The grinder mill crushes and grinds the bulk raw material into the required feeding granularity, after that bucket elevator lifts the material into the storage bin, and then electric Vibrating feeder transports it evenly into the grinding chamber where the material is scooped up by shovel blade and grinded between grinder roller and grinder ring, and then the blower blows the air into the grinding chamber from shunt plate and blows the grinded powder into the analysis chamber, the powder is concentrated by rotating analysis impeller that is driven by the speed motor with transmission gear, after the concentration, the large granular material drops back into the grinding chamber and is grinded again, and      while the qualified fine powder enters into cyclone powder collector following the air flow. When the qualified powder separates with air, it is discharged into the final product from the discharging port. In the working process of the host machine, the shovel blade plays the important role. It is in the lower end of the grinder roller and they rotate at the same time when the material is scooped up and thrown into the space between grinder roller and grinder ring thus it shapes litter layer which grinds the material with the pressure force produced by rotating grinder roller so as to achieve the goal of making powder.
