Bags are positioned on a stainless steel tabletop and then transferred through a plastic strip curtain into a dumping enclosure consisting of a glove box, empty-bag chute and dust collector located above a receiving hopper. The dust collector maintains negative pressure within the enclosure, preventing the escape of dust through the curtain, while containing dust generated during bag opening and dumping activities. A bag infeed chute through the sidewall of the enclosure allows the operator to pass empty bags directly into the bag compactor, causing dust generated from compaction as well as dumping activities to be drawn on to the system's two filter cartridges.

The compactor employs a large pneumatic air cylinder to compress bags into a removable bin that accommodates 50-80 bags. The main waste access door, and a flapper door within the bag infeed chute, are equipped with safety interlocks that prevent operation of the compactor unless both doors are closed. The hopper discharges into an enclosed Flexicon flexible screw conveyor designed to provide dustfree transfer of products ranging from large pellets to submicron powders, including those with difficult flow properties.  www.flexicon.co.uk
