A Study on Hydrocyclone with Rotating Blades on Overflow Pipe Wall
This study proposed a new type of hydrocyclone. A rotating ring containing one pair of symmetric blades was attached to the overflow pipe. The momentum of the inlet fluid drove the ring/blades to rotate, and the rotating blades swept small-sized particles to the hydrocyclone wall to be discharged from underflow. This design can destroy circulation flow on hydrocyclone roof and make small-sized particles to be separated.
