A bulk bag weigh batch eductor system from UK-based Flexicon (Europe) loosens bulk solid material that has solidified during storage and shipment, discharges the material by weight and blends it into a liquid stream.
The skid-mounted system has two bulk bag unloading frames, each with an integral bulk bag conditioner comprising a hydraulic pump and two rams with contoured end plates that press opposing sides of bulk bags. The cantilevered hoists and motorised trolleys of the unloaders allow conditioning of bulk bags at various heights, as well as loading and unloading of bags without the need for a forklift.
The configuration of the conditioner eliminates the time, labour and equipment needed for separate loading of bulk bags into a stand-alone conditioner, while taking up significantly less floor space than two separate pieces of equipment and reducing capital cost, the company says.
The unloaders also feature a Spout-Lock clamp ring that forms a high-integrity seal between the clean side of the bag spout and the clean side of the equipment, while a Tele-Tube telescoping tube maintains constant downward pressure on the clamp ring and bag spout, elongating the bag as it empties to promote complete discharge.
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.
The unloaders' surge hoppers are equipped with flexible screw conveyors that gravimetrically feed bulk solids into a central solid-liquid eductor that blends the material into a liquid stream in variable ratios set by the user.
