Weighing, batching systems for accurate dispensing

November 8, 2007

A Loss-In-Weight Bulk Bag Discharger for controlled dispensing of powder material from Spiroflow Systems, Inc. is now available that safely keeps the bag above floor level. The Spiroflow Type 3 Bulk Bag Discharger accurately dispenses from 22-pound to 3,300-pound batches by using electronic load cells directly below the top bag holding frame. This ensures that the bag and load cells are safely off the floor out of the way of facility hazards such as forklifts. As an option, an integral transfer conveyor such as a flexible screw discharge conveyor can also be suspended from the holding frame for a totally self-contained discharge and loss-in-weight dispensing system. Dust- and contamination-free, the operation can also remove partially discharged bulk bags. The bulk bag is loaded into the frame by hoist or forklift and its bottom spout is sealed within the dust cabinet of the discharge chute. Product flows from the chute into the integral flexible screw discharge conveyor. A patented spout closure device lets the operator untie the bag through an access door without releasing product from the bag. Once the access door is closed, the spout closure device can be opened to allow product flow.
