Bulk Bag Discharge Stations

Carolina Conveying’s Bulk Bag Discharge Stations are designed and built with four things in mind: Operator Safety, Dust Control, Product Discharge and Rugged Construction. All of these design features add up to the best bulk bag discharge station available on the market. Numerous options are available: Hoist & Trolley, Integral Dust Collection, Integral Bag Dump Station, Product Declumper, Batch Loss-in-Weight, Bag Tensioners and discharge feed devices such as Rotary Valves, Screw Feeders, Flexible Screw Conveyors, Aero-mechanical Conveyors, etc.

Operator Safety

The operator must never be under a suspended load per OSHA regulations, otherwise there is a hazard of being crushed. Bulk bag warning labels advise to keep clear of filled, unsupported bags. To meet these requirements, a bag must be supported from below. Carolina Conveying offers Full Platform Support, assuring optimum operator safety.

Rugged Construction

The main support frame is constructed of 4 tubular, structural steel. This heavy duty design insures that the station will not sway when loaded with even the heaviest bags. All lifting frames are load tested, stamped and certified for the required load. For units with integral hoist and trolley, the entire station is load tested and certified, all to OSHA requirements.

Dust Control

Dust control is accomplished in several ways with the Carolina Conveying Bulk Bag Station. First, product is contained with the full platform support dish. As the bottom of the bag rests on the pan, the bag seals off product to the discharge chute below. Any material that falls into the dish discharges with the rest of the product, not onto the floor. The access module below the dish allows the operator to untie the bag in a safe, dust free environment. Pinch bars inside the access module insure that product does not flow until you are ready for it. A dust extraction port at the back of the unit pulls away any dust between bag changes. A dust collection ring is also available for the top of the bag support dish.

Product Discharge

Product discharge is often difficult from bulk bags due to compaction during storage and transport. Bag shape is also not conducive to product flow, as most products do not readily flow out of a flat bottom container. The small outlet on most bulk bags also creates a bottle neck. The most effective means of discharging product from bulk bags is with massage paddles. Massage paddles break up compacted bags. They also push material into the critical flow path, which is over the bag outlet. This is accomplished with our bag massage paddles. Each paddle also has two guide rods, which eliminates twisting, bending or breaking.

Bag Closure

Carolina Conveying’s pinch bars allow dust control and flow control. After the bag is loaded into the discharge station, the spout is pulled down into the access module. The pinch bars are then closed. The operator then unties the bag spout and closes the access door. The pinch bars are then opened, allowing product to flow. This allows the bag to be untied without exposing the operator to product. Product flow can be stopped at any time by closing the pinch bars. Partial empty bags can be retied shut and removed from the station.
