Ball mill and Raymond mill are the key equipment used to grind the material, both purposes are the same for most people, it seems no difference, but in the actual use of the process, the two are still very different. Today we analyze the difference between ball mill and Raymond mill. 1. Different uses and use ranges. Ball mill is the key equipment of grinding after the material be crushed. It is widely used in cement, silicate products, new building materials, refractories, fertilizers, black and non-ferrous metal beneficiation and glass ceramics production industries, dry or wet grinding of various ores and other grindable materials. R type Raymond mill widely used in barite, calcite, potash feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass, insulation materials Mohs hardness of not more than 9.3, humidity below 6% of the non-flammable minerals, chemical, construction and other industries more than 280 kinds of high-fine powder processing materials, the finished product size 80-325 mesh within the framework of any adjustment, some of the materials up to 2,000 heads. 2. Different working principle. Ball mill is a horizontal cylindrical rotating machine, external gear drive, two positions, lattice-type ball mill. Materials from the feed device through the hollow shaft into the screw into the first mill evenly, the warehouse has a step liner or corrugated liner, built-in different specifications ball, centrifugal rotation of the cylinder to bring the ball to a certain height after the fall, the material has a heavy blow and grinding effect. After the material reaches coarse grinding in the first warehouse, it enters into the second warehouse through the single-compartment bulkhead board. The warehouse is provided with a flat lining plate and a steel ball therein to further grind the materials. Powder discharged through the discharge plate, complete grinding operations. When raymond mill work, feed the material from the hood side of the hopper into the machine, rely on hanging on the mainframe Meihua frame roller device, revolving around the vertical axis, while itself rotating, due to the centrifugal force during rotation, the roller is swung outwards and pressed against the grinding ring, so that the shovel blade shuffles the material between the grinding roller and the grinding ring, grinding roller rolling to achieve the purpose of crushing the material. 3. Different structure. Ball mill consists of the feeding part, the discharging part, the rotating part, the transmission part (reducer, small transmission gear, motor, electric control) and other major components. The hollow shaft is made of steel castings, the inner liner is removable, the rotary gear is machined by casting hobbing, and the cylinder body is provided with a wear-resistant lining plate, which has good abrasion resistance. Raymond mill mainly consists of the host, analyzer, fan, finished cyclone, fine cyclones and duct composition. Among them, the host include the rack, into the air volute, blade, grinding roller, grinding ring, and shell. 4. Different grinding range. The grinding range of raymond mill is 80-325 mesh, ball mill grinding range is between 30-300 mesh. Raymond mill output is 1-5 tons, ball mill output is 0.5-300 tons, if the milling requirements is relatively high, the general choice is raymond mill, if the production requirements of is general, use ball mill.
