Plastic Screw Conveyor Flighting

Problem: customer conveys corrosive and abrasive sludge. Standard Stainless screw conveyors wear both the OD of the screw flighting and troughs quickly. The option of adding screw conveyor hanger bearings to prolong the wear on the flights and trough is not ideal because of the high maintenance costs to maintain the bearings.

Solution: Manufacture sectional UHMW flighting to be bolted over the stainless screw flighting. This allows the customer to get the best of both worlds; the strength of stainless flighting but the wear and low coefficient of friction of plastic!
