Raymond grinder is suitable for making powder equipment at high closed circuit circle from all kinds of mine, chemical industry, building material, metallurgy. It can mill quartz, feldspar, calcite, talc, barite, fluorite, rare-earth, marble, ceramic, bauxite, manganese ore, iron mine, copper, phosphate ore, etc, which is harder than seven degree and moisure is lower than 6%. The final size can be controlled from 0.044mm to 0.125mm, which equal with that from 100 mesh to 325 mesh though Pendulum crusher
Work principle of Raymond grinder:
Firstly, raw material is crushed by jaw crusher to the size required, then elevated into a hopper from which the material is transported through the electro-magnetic vibrating feeder evenly and continuously into the grinding chamber for powder-processing. The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the middle between the ring and rollers to accomplish the grinding.After grinding, the rough materials will be recycled by the air from the fan back into the grinding chamber for regrinding and the fine powders are blew into the cyclone and poured out through the output-powder pipe as the final products.
