Screener Removes Oversize Particles from Manually Dumped Bulk Materials

Kason's Circular Vibratory Bag Dump Screener removes oversize particles from manually dumped bulk materials while protecting the operator and the plant environment from dust contamination. Integral to the mobile unit is a 40-inch (1016-mm) diameter Vibroscreen separator that causes bag scraps, agglomerates and other oversize material to travel across the screen and discharge through an upper spout, while on-size particles pass through apertures in the screen and a lower discharge spout at high rates.

Ambient air and dust from dumping activities are drawn onto the exterior of two cartridge filters that derive vacuum from a top-mounted exhaust fan. Dust accumulated on each filter's exterior surface is alternately dislodged using short blasts of air from pulse jet nozzles within the cartridge filter on a timed cycle, providing continuous, efficient operation. Dislodged material falls into the screener.

On-size material that is gravity-discharged from the screener's outlet can be fed into a conveyor or other process equipment. The Bag Dump Screener is also offered in 24-inch and 30-inch (610- and 760-mm) diameters and is available to industrial, 3-A, FDA, BISSC and other sanitary standards.
