This design was made according to this project especially, big cooling surface area of rotary cooler, design reasonable on the lifting blade, and good heat dissipation effect.

1. The motor adopt frequency control, it easy to adjust the screw feeding quantity, rotation speed of cooler, air volume, etc. 

2. Transmission system connection compact, small cover area, high transmission efficiency, and less noise;

3. It adopt gear transmission, high efficiency, less noise, and to completely seal of big gear, without oily be soiled oil pollution, clean production, and pollution-free;

4. Belting leather with roller adopts wear-resisting material, without grease lubrication, and clean pollution-free;

5. Support device adopts the circulating cooling water cooling, reduce heat conduction of heat damage of bearing, greatly improve the service life;

6. Drum steel material is 16 Mn, greatly reduce the material for cylinder wear and extend the service life of the cylinder.
