Bulk Bag Discharger and Flexible Screw Conveyor for Table Salt

This customer had existing equipment to deliver salt into their auger filler. The salt comes in bulk bags as a solidified block and is conditioned offline in a warehouse using a hydraulic bag conditioner. The primary issue for this application was to maintain a consistent, uniform material supply into the auger filler for it to operate properly. The customers’ existing discharge station features a small agitator that would break up material into irregular sized chunks that would not provide a uniform material supply into the auger filler. This results in off-spec filled packages that would need to be reprocessed. Understanding the application requirements, NBE conducted a test with the customer at our Innovation Center and Application Workshop. We used a bulk bag discharger with integral lump breaker (with screen), along with a screw conveyor, to unload the bag and process it into a consistent supply of material. The salt was broken down back to nearly original particle size. The customer was thrilled with the outcome.
