Shaftless spiral conveyors eliminate the central shaft and allow a much higher fill rate resulting in lower rpm’s, more efficient conveying and consequently less wear. Without a shaft, no intermediate or end bearings are required. The trough liner is the spiral’s replaceable bearing surface. The only machined bearings in a shaftless are in the gear reducer. This allows for direct connections and optimizes layout design flexibility. End-to-end and side connections not possible on shafted screw conveyors are common solutions available in the shaftless design. Vertical shaftless conveyors
are available in a single unit up to 50 feet and systems in excess of 100 feet in elevation gain.
Custom Conveyor Corp’s open, shaftless spiral design makes these conveyors ideally suited to efficiently convey stringy, sticky waste materials that vary in size, volume, capacity or dry solids content. They work extremely clean and efficiently for conveying materials such as:
