Raymond Mill 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, whose Moh’s hardness less than 7 degree and the moisture 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 Mill:
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.

Structural features of Raymond mill:
Firstly: It is the solid structure, cover small area; it is an independent producing system from primary material to the final powder.
Secondly: Fineness of the final powder is well-distributed, 99% of them can pass through the screen, and other milling machines are hard to approach.
Thirdly: Raymond mill commission equipment adopts closed gear case and pulley, stable convert and believable work.
Fourthly: Important part adopt high quality steel, abrasion proof adopt high quality abrasion material, the whole machine have a high abrasion and have a believable work.
Fifthly: Its electric system adopt concentrating control, the workshop can realize no-people work and maintain, etc.
