Since screw conveyor conveying space is small and it is sensitive to material, intertwining phenomenon is easy to occur when screw shaft rotates, blockage occurs in the place of hanging bearing. So blocking problem is the most common fault of screw conveyor which will affect production and increase power consumption, even the motor will burn out and screw shaft twist off which will affect the normal production. Blocking problem is caused by many reasons, we can take measures to avoid this problems:
1. Select reasonable screw conveyor technical parameters, for example, if using low speed screw conveyor the rotating speed can not be too fast.
2. Carry out the operation procedures strictly, non-load start-up and stop to ensure continuous evenly material feeding.
3. Increase the outlet or extend the chute end dimension to solve the problem of unsmooth discharging or can not discharge material timely .At the same time, you can also install a section of reversed screw blade to avoid blocking.
4. Clean up the material inside the screw conveyor in order to prevent big impurity or fibrous material enter into the screw conveyor and occurs blocking.
5. Reduce the transverse dimensions of intermediate bearing as much as possible in order to reduce the possibility of material passing through the intermediate bearing.
6. Install a level sensor and blockage sensor which can achieve the purpose of automatic control and alarm.
