About this video
The dust problem of a bulk bag station is concentrated in a few seconds at the spout. Carolina Conveying built its discharge station around that moment, and this video explains the sequence.
According to the manufacturer, the bag spout is untied inside a sealed access module that has its own dust vent. The spout is then connected to a feed tube with a pneumatic clamp that seals the spout to the tube for dust-free transfer. Pneumatic pinch bars allow the spout to be untied and retied, so a partially emptied bag can be closed and removed with material still inside. If material spills, the manufacturer states that dust and product remain contained inside the access module.
Trade coverage of the outlet spout clamp adds that the clamp ring carries a food grade gasket for a dust-tight seal, that an access door interlock disables the pneumatics when the door is open, and that the vent connects to a central dust collection system. Carolina Conveying offers the station in several designs in mild steel and stainless steel.
