The new Bulk Bag Weigh Batch Eductor System from Flexicon Corporation (Australia) loosens bulk solid material that has solidified during storage and shipment, discharges the material by weight, and blends it into a liquid stream.
A skid-mounted system, the Bulk Bag Weigh Batch Eductor System incorporates 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 unloaders feature cantilevered hoists and motorised trolleys that allow conditioning of bulk bags at various heights, as well as loading and unloading of bags without the need for a forklift. Safety interlocks disallow operation of the conditioner when the doors of the unloaders are open.
The need for extra time, labour and equipment for separate loading of bulk bags into a stand-alone conditioner is eliminated thanks to the integral configuration of the bulk bag conditioner. The Bulk Bag Weigh Batch Eductor System occupies significantly less floor space than two separate pieces of equipment, resuling in reduced capital cost.
The bulk bag 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.
A Power-Cincher flow control valve is located immediately above the clamp ring, which employs 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 Flexicon’s flexible screw conveyors that gravimetrically feed bulk solids into a central solid-liquid eductor, which blends the material into a liquid stream in variable ratios set by the user.
