Shaftless Screw Conveyor Fill Rate Basics. Shaftless screw conveyors do not have a center shaft or hanger bearings and thus have the ability to convey more materials. Typical fill rate for a shaftless screw conveyor is 30% to 45%. Keep in mind these percentages are for average consistent flows.

Vertical screw conveyors – smaller footprint, less wasted space. Vertical screw conveyors are useful for all industries that convey products through a normal screw conveyor but the additional advantage of this system is that the steeper angle allows products to be transported almost vertically via equipment that will take up much less overall floor space.
