Profile: UniTrak Powderflight Ltd specializes in bulk material handling solutions. We provide bucket elevators, aeromechanical & screw conveyors and bulk bag discharger. Powderflight™ aeromechanical conveyors operate on a simple principle. Within a tube of mild or stainless steel, a wire rope with evenly spaced discs travels at high speed, running in sprockets at each end of the conveyor. As material is fed in, it is aerated or fluidised and carried to the outlet, where it is discharged by centrifugal force. It has ability to convey material at any angle between 0° and 90° without loss of capacity. TipTrak™ bucket elevator conveyors utilize a proprietary interlocking bucket system, with extra-deep buckets and jam-proof design. Flexible screw conveyors (also known as spiral conveyor or auger conveyor) are typically used to move materials between bulk bag dischargers, storage vessels, manual sack tip or drum tip stations, screeners, crushers, blenders, reactors, packaging equipment, injection molding and extrusion machines, and other process equipment.
