Cyclones are designed to separate airborne dust, particles and foreign matters.

They are generally used to discharge the dust occurring during the processing of cereals within the machines located in the cleaning unit. Air-borne dust, particles and foreign matters are pumped into the dust cyclone by an external exhaust fan and once they enter the cyclone, foreign matters are rotated within the cyclone and fall to the bottom where they are removed by an airlock.

Air cleared of foreign matter and dust is discharged up to the air through a wide tubular duct located at the center of the cyclone.
