Shaftless Screw Conveyors are ideal for vertical conveying. Since they do not require a non-drive end bearing this eliminates the need for high maintenance bottom shafts and seals on a pulling shaftless vertical conveyor. A shaftless vertical feed is obtained by directly connected pushing shaftless conveyor which optimizes layout design ...
They are also space- and cost-efficient in transporting bulk materials. Controlling the amount of bulk material fed to the screw conveyor is critical for vertical screw conveyors to maintain a constant speed, reduce wear and power consumption, and increase the conveyor efficiency. Hence, bulk metering devices such as screw feeders are necessary.

Vertical conveying by Screw Conveyor, on the other hand, is quite successful and it remains that a 45 incline or angles approaching this figure, are the most difficult on which to achieve successful conveying. Additional power is needed to convey on an incline. This added power is a function of the power required to lift the material.
Jul 14, 2014 Actually, since an inclined screw conveyor is used to move material up vertically as well as horizontally, the amount of energy (and therefore over time, horsepower) needed to move a given amount of material would increase based on the overall height which needs to be traversed, in addition to the energy needed to move the material horizontally along the conveyor.
NBE flexible screw conveyor systems are engineered, constructed, and applied to processing and packaging operations based on the specific performance requirements of each application, such as conveying rate, angle, distance, material flow characteristics, upstream and downstream equipment integration, and automation.
