Screw/Auger. Screw conveyors, sometimes known as spiral, worm, or auger conveyors use helical elements to move materials. They consist of a helical screw element or steel auger that rotates around a central shaft, driving the work material according to the screw design and rotational direction. The helical screw functions …

Insert a coupling shaft into the next screw section and secure tightly with coupling bolts. Place screw in trough so that there is approximately 180° between lighting ends of mating screw sections. Slide screw section over the end of coupling shaft of the previous screw section. Secure tightly with coupling bolts. 9.

A 16-inch diameter screw conveyor will convey 2,496 cubic feet per hour at the maximum recommended speed of 80-rpm. The actual screw conveyor speed is calculated by dividing the Selection Capacity by the capacity at 1-rpm. 1,873/31.2 = 60-rpm. 60-rpm is the correct speed for a 16-inch diameter screw conveyor with cut and folded flights and ...

304SS made-to-order de-husking screw for soybeans. Screw conveyors have been a popular conveying method for centuries because of their ability to effectively move material with minimal losses.

best conveyor design. Since the Screw Conveyor selected is based on a maximum volume control of material to be handled, surge loads, overloads and choke feeding must be accounted for in the conveyor design. Screw feeders are popularly used for this control and are discussed in other pages of this catalog. CLASSIFY YOUR MATERIAL

The standard screw conveyor cover has minimal thickness, bolting and gasketing. To help the cover seal better, a thicker cover (10GA Min.), tighter bolting (6″ centers), better gasketing (Closed cell rubber) and 4-sided bolting are recommended. Trough End Design. Like the shaft seals the trough end can be a point of leakage.
