1. Small size,light weight,stable, no vibration,no noise,good sealing performance,no dust, high efficiency;

2. New shell structure,simple installation,convenient to control;

3. Single or multi-machines matching usage,continuous operation for a long time,safe and reliable;

4. Scouring the screen by cyclone,automatic mesh cleaning;

5. Re-crushing function of the blocked material;

6. New spherical bearing,prolonging the service life;

7. The machine can be matched with pneumatic conveying system,and directly string into the wind road to conserve energy;

8. New design:gas protection system will convey purified air to both ends of equipment, so that effectively reduce the temperature produced in the operation process;

9. Gas barrier layer is formed on the bearing to prevent dust entering,so that can effectively prolong the service life of the bearing,reduce maintenance frequency,and improve work efficiency.
