How to prevent material clogging during screw conveyor conveying?

The screw conveyor can transport granular, powdery and small block materials, etc. During the conveying process, due to the small space for the screw conveyor to transport the material, the screw shaft drives the material to rotate and is easy to entangle with the material when it is transported forward. The middle suspension bearing is therefore It is easy to block the material. If the blockage occurs, it will affect the normal use of the machine, increase the power consumption, and even burn the motor, and the screw shaft will be broken, which will affect the normal production.

How to prevent material clogging during the conveying process of the screw conveyor?

1. During the conveying process, the operator must strictly implement the operating procedures, start without load, and ensure continuous and uniform feeding during the conveying process. It must be stopped when it is empty, and it cannot be conveyed without empty load. It can also be used with a vibrating feeder to achieve uniform feeding and reduce the chance of screw conveyor blockage.

2 During the use process, the parameters of the screw conveyor should be carefully selected, and the conveying angle, conveyor speed, motor power, etc. should be selected in a reasonable design with reference to the conveying distance of the application site and the characteristics of the conveyed materials.

3 Before conveying materials, the materials entering the conveyor should be cleaned up as necessary to prevent large impurities or fibrous impurities from entering the machine and causing blockage. Minimize the transverse dimension of the intermediate suspension bearing as much as possible to reduce the possibility of material blocking when the material passes through the intermediate bearing. In addition, it is also possible to install a silo level sensor and a blockage sensor to realize automatic control and alarm.

4. It is possible to increase the outlet of the screw conveyor or lengthen the end of the trough, and install a small section of anti-rotating blades at the end of the chute at the outlet to prevent the end from being blocked. At the same time, an anti-blocking valve can also be set on the discharge end cover plate. If blockage occurs, open the anti-blocking door to clean up the blocked material.
