The WAM SSC shaftless screw conveyor is an alternative concept to the traditional shafted screw conveyor. The Shaftless Screw (spiral) offers a larger volume capacity and the capability of handling particularly difficult materials such as those that tend to become tangled up or those that present highly variable particle size. Construction material properties, oversize thickness, as well as a special manufacturing process make the spiral highly resistant and extremely durable. Due to the absence of intermediate bearings, obstacle-free material handling is guaranteed. The completely enclosed trough prevents any material leakage. Trough covers with appropriate gaskets enable odor-free operation and prevent contaminants from entering the system. At the same time the conveyor offers maximum access to the inside for inspection and cleaning. Maintenance is reduced to the minimum due to a small number of components. There is a vast choice of liners depending on the specific material characteristics.
