SHAFTLESS SPIRAL CONVEORS
Negligible liner wear, as spiral not riding on the liner. Up to 13m (40ft) lift per stage, up to 3 stages. Typically feed into horizontal conveyors. Typically in pulling arrangement for sludge. Typically in pushing arrangement for screenings. Higher RPM, typically 2x horizontal feed conveyor RPM.

Environmental Shafted Screw Conveyors | Features & Benefits
Since the rotating element (spiral) rests on the trough liner with zero clearance between the liner and spiral, shaftless screw conveyors are more efficient than shafted screw conveyors. Conveying efficiency is comparable when the screw conveyor is located in the horizontal position, but the greater the incline of the conveyor, the greater the ...
