The screw conveyor system collects and conveys the dirty media mix from the floor hoppers to the recycling system.It consists of a set of long auger assemblies that move the media mix all the way to the end of the room, where the load is discharged into a bigger transverse auger assembly.
At the end of the transverse auger assembly, the whole blast booth load is then discharged into a bucket elevator after passing through a rotary screen drum to remove large debris from the dirty media mix.
Screw Conveyor is a key component of the mechanical recovery system. The auger’s shaft and steel flights are made of steel alloys specially designed to withstand heavy load demands.
All DISA screw conveyors have a mild steel hopper that is installed in the foundation, fitted in this is the screw conveyor mounted on heavy duty self aligning bearings. The bearings are sealed from the ingress of abrasive for long life, long screw conveyors have a hanger bearing mounted every six metres for support.

Advantage:
Disa screw conveyor flight is made from 6mm thick steel welded to a seamless pipe. Each screw conveyor flight is supplied in a length equal to its diameter so replacement of a small section when wear occurs is very easy.
The shedder fitted above the screw conveyor stops any large items from entering the screw conveyor.
