Principle/Structure

This is a separation device that uses the power of air to remove even fine particles that cannot be separated with a sieve.

1. In the cyclone zone, foreign objects are carried away by rising air currents, and raw materials are decelerated by gravity and fall.
2. In the jet zone, fine particles attached to the raw materials are blown away with a jet stream.
3. In the terminal zone, tertiary air is blown up to carry the separated fine powder upward.
4. The air-cleaned material is discharged from the bottom of the device.

Performance

Film (ribbon) removal rate

The figure below shows the results of a separation test in which finely cut film (ribbon) was mixed with plastic pellets. Almost 100% separation is achieved by supplying secondary air and tertiary air.
