Flexicon has launched a combination bulk bag and manual dump batching system to weigh materials that are discharged from bulk bags and manually dumped from sacks, boxes and other containers, and empties the batch into mobile storage bins.
Flexicon’s weigh batch system consists of a bulk bag unloading frame, two hoppers, and two flexible screw conveyors that feed a central gain-in-weight hopper under automated control.
A programmable controller with a manual start button activates the flexible screw conveyor to load the first ingredient into the central weigh hopper at maximum feed rate or can start and stop the second conveyor to load the second ingredient into the weigh hopper. It can also activate hopper’s slide gate valve to discharge the batch into mobile storage bins.
The unloader features a Spout-Lock clamp ring that forms a seal between the clean side of both the bag spout and equipment. To promote total evacuation of material, a Tele-Tube telescoping tube maintains constant downward pressure on the clamp ring and bag spout, elongating the bag as it empties, while Flow-Flexer bag activators raise and lower bottom edges of the bag into a steep “V” shape, directing material into the bag outlet spout.
According to Flexicon, immediately above the clamp ring is a Power-Cincher flow control valve employing a series of curved, articulated rods that cinch the bag spout concentrically, allowing dust-free retying and removal of partially-empty bags. A removable bag-lifting frame with bag strap hooks and fork tubes allows loading of the lifting frame with bag intact, onto a cradle at the top of the unloaded frame posts.
The company said the machine is suitable for free- and non-free-flowing bulk materials including products that pack, cake, smear or easily degrade, with no separation of blended products.
