Raymond Mill(Grinding Mill) produced by our company is 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 and so on. The final products can be adjusted freely from 100 mesh to 425 mesh.

Working 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.

Characteristics Of The Raymond Mill(Grinding Mill):

The diameters of each part of rollers and rings are different, the upper part is big and the lower part is small, then they formed a trapezium form. This form can reduce materials’ sliding speed downwards and prolong the grinding time for materials, thus the grinding efficiency is increased.; the pressing springs have the functions of balancing and pressure increasing; the flexible connection can make the mill stable, decrease the shocking and avoid sympathetic vibration; high density powder seperator impeller decreases the air resistance and increases powder collecting fineness and capacity; the efficiency of energy saving and high efficient centrifugal blower is as high as 83%.
