Does the direction of the screw conveyor affect the direction of the motor

The rotation direction of the screw conveyor has a direct impact on the direction of the motor. The rotation direction of a screw conveyor is usually divided into clockwise (right-handed) and counterclockwise (left-handed). The judgment method is as follows: stand at the motor drive end (usually the connection end of the reducer) and observe. If the screw shaft rotates clockwise, it is right-handed; Reverse needle rotation is left rotation. In addition, the direction of blade helix also affects the determination of rotation direction. Blades with right-handed helix follow the right-hand rule, while those with left-handed helix follow the opposite rule.

Wrong motor direction can cause equipment failure. If the motor wiring is incorrect and causes reverse rotation, it may cause material blockage or damage to the equipment, so it is necessary to strictly check the motor wiring. Choosing the correct rotation direction of the screw conveyor can not only improve conveying efficiency, but also reduce failure rates and extend equipment lifespan.

The conveying direction of a screw conveyor is determined by the direction of the blades, not the rotation direction of the main shaft. The pitch size also affects the conveying effect of materials, and the appropriate pitch size needs to consider the friction relationship between the helical surface and the material, as well as the appropriate distribution relationship between the velocity components.
