WLS shaftless screw conveyor based on environmental, paper, chemical, food, pharmaceutical, beverage and other industries transport station attached stronger materials are widely used, easy to wound paste sticky materials and materials, has a unique advantage. So shaftless screw conveyors, also known as anti-winding, garbage conveyor. WLS-type shaftless screw conveyor is our technical department in the design and production of various types of screw conveyor on the basis of experience, according to the national similar products, in conjunction with relevant scientific research departments and the design and development of a new type of conveyor products. WLS-type shaftless screw conveyor on the conveyor screw conveyor with the general principle is basically the same: that as a rotating screw shaft, drive like a nut along its axial movement, shaftless screw conveyor spiral helix axis corresponds to the material equivalent nut screw conveyor, spiral continuous rotation when the materials are continuously fed. Shaftless screw conveyor spiral ribbon for thicker blades driven by shaftless screw conveyor drive end, middle shaftless spiral slide body contact with the inner wall of the housing bottom liner.
