Coal Crusher & Crusher

Raymond Mill

Raymond mill (also named raymond grinder mill)is featured by the advantages of high output, fine powder, continuous powder production with dry method, centralized particle size distribution, continuous and adjustable fineness, compact structure, low energy consumption, high efficiency, low power consumption, small covered area, little one-time investment, easy installation and maintenance as well as reliable operation etc. Raymond mill is applicable to the dry-type super-fine powder process of mineral materials. Therefore, it’s the ideal equipment for grinding industries, especially for small-size enterprises.

Raymond Mill Applying Area

Raymond Mill is used to grind barite, calcite, potash feldspar, talcum, marble, limestone, ceram and slag below scale 7 of Moth's hardness and 280-odd sorts of non-inflammable and non-explosive stuff in the traded of mining, building material, chemical engineering and metallurgy for power generation and processing. The product size is adjustable on required in the range of 100-325 meshes.

Raymond Mill Working Principle

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.

Raymond Mill Features:

1.Three-dimensional structure , land-saving, easy to be a whole set

2.The screen-passing rate can reach to 99%

3.The transmission is steady and reliable;

4.Centralized control for the electric system, convenient to operate
