Spiroflow has added the DYNAFLOW Tubular Chain Drag Conveyor to its range of conveyors. The DYNAFLOW conveyor offers a totally enclosed, dust-free, contamination-free handling of hot, cold, wet, dry, hygroscopic or temperature sensitive materials. It operates in three planes to permit complex circuits, eliminates transfer points and using only a single drive for minimum energy consumption. The system may be fed or discharge at multiple points in a circuit. There is no need for filters or cyclone to separate air and material since no additional air is introduced into the system.
