This is a combination of horizontal and vertical screws which is used to feed the powder in the silos. The system consists of a Horizontal Screw Feeder, which is either designed for feeding from bag hoppers or from silos, and a Vertical Screw Conveyor. Material is discharged by the Vertical Screw into a weigh hopper, one or more silos, or into further conveying systems. Fabricated parts, screws, end bearing and intermediate bearing assemblies, which offer particular maintenance-friendliness, have been specially designed for this system. The VE Vertical Screw Conveyor system stands out for its high volumetric and mechanical conveying efficiency achieved.
