Raymond Mill

Brief introduction of raymond mill

Raymond mill producedis mainly used to grind non-inflammable and non-explosive materials with moh's hardness below 7 and moisture content below 6% such

as barite, calcite, potash feldspar,talcum, marble, limestone, ceramic, glass, etc. Raymond mill

can be used in mining, chemical industry, construction materials, metallurgy, etc. The final

products can be adjustedfreely from 100 mesh to 425 mesh.

Working Process of raymond mill

Firstly, raw materials are 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.
