Troubleshooting of Screw Conveyor

1. Connecting bolt broken easily

As for the screw conveyor made up of couple sections, the connecting bolt located in the head section bearing the full motor torque, while the rear screw segments and the connecting bolt bearing the decreasing torque. Therefore, the connecting bolt located in the head section broken easily.

Solution: Using the high-strength bolt in the head section, if necessary, you can also adopt three bolt connect, so that insure the screw conveyor can normal operation and avoid the connecting bolt become shorten

2. Suspension bearing wear easily

There are many factors can affect the suspension bearing wear, such as working environment, working conditions, the characteristic of conveying material, suspension bearing structure, quality etc. Especially when operation the suspension buried in the material, if sealed and lubricated is not good enough then the material particle will easily fall into the connecting surface of bush and journal, which will make wear faster.

Solution: choose the wear-resistance bush and assurance the quality; besides you also should keep good seal and lubricated to extend the work life of the suspension bearing.

3. Suspension bearing installed improper makes the screw locked or bending

Solution: Suspension bearing should be mounted concentric with the connecting shaft and insure that all suspension bearings concentricity to insure that wire helix of each segment.

There should leave some place between end and the screw shaft end usually is 10-20mm; Each suspension bearing halves should be connected firmly, tight, and it should be keep proper radial clearance to ensure screw flexible rotation.

4. Too many materials piled up in the inlet

Too many materials piled up in the inlet actually mean that the screw conveyor emerge blockage trouble. For strong bagging feature, humidity, large bulk material, especially under the case that can’t feed uniformly, this trouble is easily to happen.

Solution: You are not allowed to feeding materials that can’t meet the conveying request; feeding should be uniform; In order to avoid trough distortion you are not allowed to beat the charging port.
