The modular shafted screw conveyor system is highly versatile offering numerous solutions for conveying flowable bulk solids materials. Shafted screw conveyors are manufactured from mild steel, AR (abrasion resistant) steel, stainless steel and other alloys, with a suitable surface finishing. They are made up from a U or V-shape trough that is equipped with at least one outlet spout, an end plate at each trough end, helicoid or sectional screw flighting welded on a center pipe bushed at each end, end bearing assemblies complete with shaft sealing unit, a certain number of intermediate hanger bearings depending on the overall length of the screw conveyor, and bolted trough cover sections. Shafted screw conveyors are equipped with a gear drive that suits the application. Screw feeders or live bottom conveyors with multiple screws in a common housing are available for applications such as bin unloading. Depending on the material to be handled shafted screw conveyors can be fabricated in a U.S. industry standard Group 1, Group 2, and Group 3 component construction.
