The solution to the blockage of the screw feeder

1. Reasonably select the technical parameters of the screw feeder, such as the speed of the slow screw conveyor should not be too large.

2. Strictly implement the operating procedures to achieve no-load start and no-load parking; ensure that the feeding is evenly continuous.

3. Increase the discharge port or lengthen the end of the trough to deal with the problem of poor discharge or too late to discharge. At the same time, a small section of counter-rotating vanes can also be installed at the end of the material trough at the discharge port to prevent the material from being blocked at the end.

4. Make necessary arrangements for the materials entering the screw feeder to prevent large debris or fibrous impurities from entering the machine and causing blockage.

5. Reduce the lateral size of the central suspension bearing as much as possible to reduce the possibility of material blocking when the material passes through the central bearing.

6. Install silo material level device and blocking sensor to complete automatic control and alarm.

7. Set up an anti-blocking valve on the discharge end cover. When a blockage occurs, due to the accumulation of materials, the anti-blocking door is opened, and the power supply is blocked through the travel switch at the same time.
