Three cutting screw conveyor screw conveyor structure used several structures: the dual screw conveyor transporting material structure, under a single screw conveyor transporting material structure with electromagnetic oscillator cone material structure, the following were introduced about three Under the next species feed structure and make a simple comparison, the next material structure with an electromagnetic oscillator tapered cone material with an electromagnetic oscillator configuration enables hanging stagnation, consolidation, strong adhesion loose material activation, to prevent the material next expected When knot arch bridge and cross-flow phenomenon. The structure is added to the hopper discharge opening at one end of the first vibration, the vibration of the hopper cone living space occupied by the arch-taking, both to undermine knot knot arch arch can use to enclose the stream, even played a role in the intermittent feed . 2, double screw conveyor transporting material structure under double screw conveyor connected by the same shaft by a motor reducer drive consolidation powder block rotation of the screw conveyor for the damage caused by a large backlog of powder form, the small screw to crude feed section for conveying ultrafine low adhesion material. 3, single screw conveyor transporting material structure under a single screw conveyor structure is a lower conical hopper discharge port has a screw feeder, depending on the quantity, the use of speed regulator under the control of the amount of material, depending on the Media and the amount may be. Auger driven by one motor reducer, enabling stepless speed, which is characterized by high material to precision, small error, no arch bridge junction obstruction. General
