When the screw conveyor assembly to ensure concentricity of the production process is the most important prerequisite determines the service life of the screw conveyor and screw conveyor effect. Screw conveyor is driven by a motor reducer screw shaft, to achieve the material transport. Screw conveyor screw shaft and motor reducer is in the same line, during assembly, to pay special attention to concentricity motor reducer unit and screw spindle. High concentricity screw conveyor at work low energy consumption, less resistance, low noise effect obviously, will not cause wear and tear on other parts, the whole long life. Concentricity lower screw conveyor, when in use, high noise resistance, higher electrical load easy to burn.
