The new bulk bag weigh batch eductor
system 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 incorporates two bulk bag
unloading frames, each with an integral bulk bag conditioner comprised of a
hydraulic pump and two rams with contoured end plates that press opposing sides
of bulk bags. The cantilevered hoists and motorized trolleys 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 unloaders’ doors are open. Integral configuration of the conditioner
eliminates the time, labor and equipment needed for separate loading of bulk
bags into a stand-alone conditioner, while consuming significantly less floor
space than two separate pieces of equipment and reducing capital cost,
according to the company. The unloaders also feature a 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 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 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.
