Screw conveyors are of simple, relatively low cost construction compared to other conveyor systems. Screw conveying systems consist of a helical flight fastened around a pipe or solid shaft, mounted within a tubular or U-shaped trough. As the screw rotates, material heaps up in front of the advancing flight and is pushed through the trough. Particles in the heap next to the flight surface are carried part way up the flight surface, and then flow down on the forward-moving side of the heap.
These conveyors can handle a wide variety of solid particles ranging from lumps to powders. Lumpy, sticky, or fibrous materials may cause problems in a screw conveyors.
Screw conveyors serve the manufacturing industry in a wide variety of applications: conveying, distributing, collecting, mixing, heating, cooling, elevating, batching, blending, aerating, and providing crystallization or coagulant action.
Screw conveyors systems and components must be accurately and ruggedly built to withstand the daily rigors of the entire manufacturing process. Orthman Conveying Systems' screw conveyors and components meet all CEMA specifications, and are accurately and RUGGEDLY built!
