The new BULK-OUT low-profile discharger from Flexicon (Bethlehem, PA) positions Intermediate Bulk Containers (IBCs) weighing up to 3,200 lbs. (1450 kg) in the frame using an electric hoist and trolley, discharges bulk solid materials into a surge hopper and conveys the material to a downstream process dust-free. The process includes the following:
- Lifting arms fitted with four eye hooks connect to the mobile IBC frame, which is equipped with four inverted cradle cups that mate with corresponding posts on the discharger frame for precise positioning of the IBC outlet.
- When lowered into position, the tapered outlet of the IBC’s butterfly discharge valve mates with a gasketed receiving ring on the lid of a surge hopper, allowing opening of the valve and discharging of material with no dusting.
- A port on the lid of the surge hopper is vented to a BAG-VAC dust collector that puts the sealed system under negative pressure, preventing displaced air and dust from entering the plant atmosphere.
The surge hopper is available with an integral flexible screw conveyor, tubular cable conveyor or pneumatic conveying system also produced by the company. All material contact surfaces of the system are of stainless steel with the exception of the flexible screw conveyor’s polymer outer tube.
