1.Raymond mill with ISO9001:2008 approved 2.Particle size form 80~600 mesh 3.Patent no: ZL2011201414398 4.2~20t/h

The Technical characteristics of China high quality GLHD Raymond mill

1. reducer adopting new deceleration device:main engine revolution may according to the different working conditions, can be adjusted main engine revolution, to adapt to different hardness materials.

2.shovel material using super large: use the big Shovel blade, makes the material tackles the into grinding roll and a magic ring between grinding. 

3. classifying precision: using super-large grading turbine, percent of pass is high, deal with big air volume. And grading impeller end and powder outlet end forming palace type sealing, the system doesn't easy to form short-circuit powder, classification precision is high.

4. double whirlwind: the parallel double whirlwind collector, collecting efficiency over 80%, than the single tornado collector5%-- 10% collection efficiency. 

6. carrying ability: blower adopts high voltage centrifugal fan, air volume and air pressure increases, greatly improve the pneumatic conveying capacity.

7. afterwind adopts baghouse collecting, no dust pollution.

Working Principles of China high quality GLHD Raymond mill

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 is 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 airflow system is closely sealed up and circulated under condition of negative and positive pressure.
