Raymond mill is a commonly used industrial pulverizing equipment, which is commonly used for pulverizing and processing more than 280 kinds of materials in mining, building materials, chemical industry, metallurgy and other industries with Mohs hardness of barite, calcite, potassium feldspar, talc, marble, limestone, ceramics, glass and other non flammable and explosive materials with humidity of less than 6%. The grinding particle size is adjusted in the range of 80 ~ 400 mesh. Raymond Mill Working Principle During the operation of Raymond machine, the materials to be crushed are added into the machine from the feed hopper on the side of the machine cover. Relying on the grinding roller device suspended on the plum blossom frame of the main machine, it rotates around the vertical axis and rotates itself at the same time. Due to the centrifugal force during rotation, the grinding roller swings outward and presses tightly against the grinding ring, so that the shovel blade sco...
