For bulk bag discharging, the bag outlet is pulled through a top-mounted iris valve that is closed around the spout, preventing material flow. The spout can then be untied, the access door closed, and the valve released slowly, reducing uncontrolled bursts of material into the hopper and dust into the plant environment.
For manual dumping in conjunction with or independent of bulk bag discharging, the operator simply raises the hinged door and pours material through a coarse screen into the hopper. When equipped with optional dust collector, the unit prevents contamination of the product and plant environment.
BFF Series dischargers are equipped with top-mounted receiving cups and removable bag-lifting frames for forklift loading of bulk bags. New Z-CLIP™ strap holders* allow rapid, secure insertion and removal of bag straps.
Optional flexible screw conveyors, also manufactured by Flexicon, transport both free-flowing and non-free-flowing bulk materials including products that pack, cake, smear, seize or fluidize, with no separation of blended products.
The discharger can also be configured for bulk bag weigh batch discharging with the addition of load cells and a programmable controller.
Units are available in carbon steel with durable industrial coating, or stainless steel to industrial, food, dairy or pharmaceutical standards.
