Centrifugal Sifter with Bag Dump Station


Centrifugal Sifter with Bag Dump Station

A new Centri-SifterTM centrifugal sifter with integral bag dump station and dust collector removes bag scraps and other oversize contaminants from manually dumped bulk materials while protecting the operator and plant environment against dust contamination.

Configured for installation on a mezzanine, the system gravity-discharges into process equipment, and affords a sufficiently low deck height for operators to dump sacks and other containers.

Ambient air and dust from dumping activities is drawn onto the exterior of two cartridge filters that derive vacuum from a top-mounted exhaust fan. Dust accumulated on the filter's exterior surfaces is dislodged by overcoming continuous negative pressure within the cartridge filters, with positive pressure introduced in short blasts on a timed cycle by pulse jet nozzles. Dislodged material falls into the screener while instant resumption of negative pressure collects any dust generated by the filter cleansing operation.

Centrifugal action created by rotating helical paddles accelerates the rate at which on-size particles pass through a horizontal screen cylinder. Oversize material is propelled through the downstream end of the screen cylinder to a discharge spout.

The Bag Dump Screener is constructed of stainless steel and finished to industrial, food, dairy and pharmaceutical standards.
