Mongolia is mainly used for milling machining grinding hardness of materials, models 3R1510 Raymond Raymond, 3R2615 Raymond, 3R2715 Raymond mill and the like. Raymond is widely used in mine lime, calcite, feldspar, lime, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, plaster, glass, insulation materials Mohs hardness less than 9.3, lime powder processing humidity below 6% of non-flammable mineral, chemical, construction and other industries more than 280 kinds of materials, R-type Raymond mill product size 80-325 inner mesh of arbitrary regulation, part of the material up to 2000 mesh. 5R4119 / 4R3216 type Raymond equipment: jaw crusher, bucket elevator, electromagnetic vibrating feeder, gear, host, analysis machine, plumbing fixtures and blowers. The machine uses advanced structure of similar products at home and abroad, and to update the industry on the basis of Raymond mill from the improved design of the device is higher than the ball mill efficiency, low power consumption, small footprint, a small one-time investment. Roller centrifugal force of the tightly compacted in the grinding ring, so when the roller, grinding ring wear to a certain thickness does not affect the yield and fineness of the finished product. Roller, grinding ring replacement cycle is long, thus excluding the wearing parts centrifugal mill short replacement cycle defects. Aircraft winnowing fan airflow is - mill shell - Cyclone - circulation fan inside job, so less dust than the high-speed centrifugal mill, operating plant clean, environmental pollution.
