Screw flights or screw conveyors are mostly used for transport/conveying dusty, granular and fibrous materials. Screw conveyors can also be used as mixers during conveyance, for example in concrete conveying.
A screw conveyor usually lies in a steel trough and transports the bulk material over a distance of up to 60 metres.
The screw conveyor consists of a worm thread and a so-called worm shaft with a drive and a final bearing shaft end.
We can offer you a wide range of designs such as simple blades, serrated blades, conical blades, blades with irregular pitch, with and without shaft, etc.
