SBM Raymond Mill
SBM raymond mill can be used for grinding barite, calcite, potash feldspar, talc, marble, ceramic, glass and some other material that Moh's hardness degree is below 7, humidity is in 6%, and non-flammable non-explosive minerals. The grinding mill plant can be made up of the raymond mill mainframe, Separator, Pipeline System, Air Blower, Jaw Crusher, Hopper Elevator, Electromagnetic Vibrating Feeder, and Electric Control Motor and so on .

Raymond mill operation
The whole raymond grinding mill plant is a vertical structure of strong systematic characteristic, so it occupies small area. From crushing of raw material to grinding and packing is an independent production system.

Raymond mill maintenance
During the application of the raymond mill, some personnel shall be arranged to take responsibility of management. The operators must be qualified with the required technical knowledge. Before the installation of the grinding mill, the persons related to the operation should receive technical training and fully understand the operating principle, performance and regulations of the raymond mill.
In order to guarantee the raymond mill in a normal working state, a Safety Operation System for the Maintenance of the equipment must be established. Only in this way can this grinding mill be guaranteed to have a long-term and safe operation. Meanwhile, it is necessary to have the required repairing tools, lubricant and grease, spare parts and accessories.
After some period of running, the raymond mill should receive an examination and repairing. The components vulnerable to worn out, such as grinding roller, grinding ring, relieving tool etc. should be repaired or replaced. Before and after the operation, a careful examination should be carried out for the connecting screws, bolts and nuts on the grinding rollers so as to find whether they are loose or sufficiently lubricated.
When their application time surpassing about 500 hours, all the rolling bearings in the roller sleeves must be cleaned, and the damaged parts should be replaced. The oiling tool can be either a manual oiling pump or grease gun.

Raymond mill working principle
Firstly, raw material is crushed by jaw crusher to the size required, and then the crushed materials are 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 ring and roller to accomplish the grind.
After this, the ground stuff are carried by the air from the blower into the separator for screening. The fine powers are blow into the cyclone collector and are poured out through the output-powder valve as the final products and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding. The set’s airflow system is closely sealed up and circulated under condition of negative and positive pressure.
