Custom Screw Conveyors from stock components. Standard duty thru heavy duty, carbon steel,stainless steel and galvanized are available. For special flight designs or a solution to a particular problem, contact our office. Screw conveyors are bulk material handling equipment capable of moving a vast variety of materials. The material is moved by a rotating screw that pushes or pulls the material along the bottom and sides of the conveyor housing, shearing the material in the radial clearance between the screw and conveyor housing and causing the material to tumble upon itself as the rotating screw's face tends to lift the material. |
