Kason Corp.'s Vibro-Air size/density separator employs vibratory screening and airflow to remove fines, angel hair, strands and film scrap from pellets and ground or chopped plastics.
Applications include extruded pellets, regrind and recycled plastics.
Material fed through a port on the unit's hood cascades over a series of strategically placed internal trays, onto a vibrating, fine-mesh screen that moves correctly sized material through a discharge port. Heavier fines pass through the screen onto a chute leading to a lower discharge spout.
At the same time, air drawn into the base of the airtight chamber blows upward, drawing low-density materials like angel hair, strands, film scrap and dust from the vibrating trays into an airstream that increases in velocity, as the hood tapers, before venting to a cyclone and/or a dust collector.
The combination of airflow and vibration is effective at overcoming the static-charge attraction between plastic particles that screening alone may not, said Kason President Henry Alamzad.
Kason is based in Millburn, N.J.
