Features and benefits

 

1) Adopting unique sealing technology, reduce 40% energy consumption, capacity increases 45%.
2) Special screw guide plate mounted at the inlet to avoid bonding and pile up of wet material.
3) Single drum design for industry use.
4) Heating source could be coal, gas, electricity.
5) Low energy consumption
6) High capacity
 

 

The three cylinder rotary dryer is applied to dry wet material, which size is less than 20mm. The material could be coal, slag, concentrate, sand and etc. The rotary dryer shell is self-insulation, thermal efficiency up to 80%, the production increase 100%. The whole shell length is shorter than the single drum 60%, it is good for the technology layout, reduce the factory area, and reduce the foundation investment. It is high efficiency, outside of the cylinder is 60 degree, the discharging temperature is lower than 60 degree. The outlet temperature is low, which can increase the dust collector equipment
