WORKING METHOD:

 

 

The material falls onto the material balancing plate and accumulates a certain thickness,

 

to prevent the fresh air flowing into the aspiration channel.

 

 

Low density impurity following with air from aspiration channel flows into the separation

 

area when the material flows into the aspiration channel. The separation effect can be

 

adjusted by the adjusting plate.

 

 

 

The separated low density impurity enters into the separating cylinder following with

 

circulating airflow. Under the influence of separating cylinder, the low density impurity

 

will be separated from airflow and fall into the dust collecting chamber. And then the

 

low density impurity enters into the screw conveyor airlock guided by the collecting

 

screw conveyor at the lower part of the collection chamber and then discharged by

 

the screw conveyor airlock. 

 

 

The fan sucks the purified air and returns it to the aspiration

 

through the return channel.The purified material is directly entering into the outlet

 

hopper. The pressure valve is opened under the influence of the gravity of the

 

material, then the material is discharged and enters into the next process.
