1. application:
Raymond Mill is applicable to the grinding and processing of more than 280 kinds of non-flammable and non-explosive materials with hardness less than 7 and humidity less than 6% in mining, construction, chemical industry and metallurgy, such as barite, calcite, feldspar, talcum, marble, limestone, clay, glass. The fineness of the finished product can be adjusted from 100 mesh to 325 mesh according to requirements.
2. features:
1) The concrete base weight required is only 3 times of that of other similar machines thus the construction expenses is greatly reduced ;
2) Small vibration while using and doesn't need shock-absorbing device;
3) Large load adjustment scope, so it can run under various environments;
4) Can bear very strong explosion pressure;
5) The grinding roller adopts new material and new craft, which ensures long service life and low maintenance cost;
6) There is gap between the grinding parts; it can start with load or offload.
3. Working principle:
The motor dives the grinding table to turn through the speed reducer. At the same time, hot air comes into the roller mill from the air inlet. The materials fall down the centre of grinding table from the feeder. Because of the centrifugal force, the materials move to the edge of grinding table from the centre .The materials are crushed by the grinding roller when by pass of the groove on the grinding table. The crusher materials continue to move to the edge of the grinding table until taken away by the airstream. Then the bigger materials fall down the grinding table and the process of crushing continues. When the materials in the airstream pass the separator on the top of the mill, the materials fall down the grinding table from the taper filler under the force of guide leaf blade. The fine powder comes out with the airstream, and is gathered by the dust catcher of the system. The powder gathered is the final product of roller mill. In the process of the contact of airstream , the materials are dried to meet the clients’ need at the proper moisture. Through the adjustment of the angle between the separator and the leaf of wind’s direction (not suitable to the small type of vertical mill), and also the speed of the separator rotor, it can reach the proper fineness of the materials.
