Description of Raymond Mill:
Raymond Mill is widely used in barite, calcite, potash feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite,kaolin, cement, phosphate rock, gypsum,Mons hardness of the glass, insulation materials, etc. is not greater than 9.3 and humidity below 6% non-explosive minerals,chemicals, construction and other industries more than 280 kinds of material for high fine powder generation and processing, the R-type Raymond mill machine finishedparticle size of 80-325 mesh within arbitrary regulation, part of the material up to 600 mesh.

Working Principle of Raymond Mill

Firstly, raw material is crushed by jaw crusher to the size required, 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 ringbecause 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

The Main Features of Raymond Mill:
1. The whole mill is of spatial structure , less premise and systemic strong. The whole system from roughing, transportation, powder collecting to packaging forms a independent production system.
2. Even granularity, sieving rate 99%, which is unapproachable for other mills.
3. The driving device applies in closed gear box and belt pulley, so the transmission is calm and the operation is reliable.
4. All the main parts of Raymond Mill adopt high quality steel, the resistant parts use high-performance proof materials, so the whole system has high wear resistance and reliable performance. The blade frame of the main machine keeps in touch with the materials , it is consisted of the upper part and lower part, when the lower partis worn down , just take down the bolts to exchange it .
5. Centralized controlling of the electrical system, unmanned operation , easy maintenance.
6. Less dust pollution, low noise.
7. Adopting electro-vibrating feeder , it can feed evenly and is easy to adjust, features miniature size, light in weight, power saving and easy maintenance.
