Stone Grinder

grind non-inflammable and non-explosive materials, barite, calcite, potash feldspar, talcum, marble, limestone, etc.

Raymond Mill: Raymond mill produced by our company is mainly used to grind non-inflammable and non-explosive materials with Mohs hardness below 7 and moisture content below 6% such as barite, calcite, potash feldspar, talcum, marble, limestone, ceramic, glass, etc Raymond grinder can be used in mining, chemical industry, construction materials, metallurgy and so on. The final products can be adjusted freely from 100 mesh to 425 mesh. Working 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.
