Kason: Centrifugal Screener With Bag Dump Station
March 21, 2005
Kason Corp.'s new Centri-Sifter(R) centrifugal screener 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 filters' 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.
