What should I do if the screw conveyor is blocked?

The screw conveyor is a tool for conveying powdery materials. Due to its large conveying capacity and no pollution, it is currently widely used. The most common failure of the screw conveyor during use is material blocking. Once the material is blocked, it will delay time. So why does the material blockage happen?

1. Failure to feed evenly

In fact, most of the screw conveyors are prone to material blocking failures, which are caused by the operators not strictly operating in accordance with the operating specifications. The operator should ensure that there is no load when starting up, and the feeding should be uniform. The conveyor must be stopped when it is empty, and it cannot be operated without a load. The wear of the large conveyor, so it should be gradually increased during the feeding process, and the rated conveying capacity should be gradually reached.
Solution: Feed evenly or install a vibrating feeder.

2. Not taking into account the conveying materials, conveying volume, conveyor speed, motor power, etc.

Usually, when choosing a screw conveyor, it is necessary to consider the conveying material, conveying volume, conveyor speed, motor power, etc. If the selected conveyor and the material to be conveyed do not match the achieved effect, it is easy to cause the conveyor to be blocked. question.
Solution: Select the conveying volume, the speed of the conveyor, the power of the motor, etc. that match the material to be conveyed.

3. Failure to clean up impurities in time after conveying materials

After the screw conveyor has conveyed the material, there must be impurities in the machine. If the necessary cleaning is not carried out, the residual large impurities or fiber impurities will cause blockage.
Solution: In order to reduce the occurrence of material blocking, the inside of the machine should be cleaned in time after the material is conveyed.

4. The lateral dimension of the bearing is too long

This point is actually easy to be overlooked. After all, no one would have thought that if the horizontal dimension of the bearing is too long, it will also cause material blockage. However, it has been proved that if the horizontal dimension of the conveyor bearing is too long, it is very easy to cause material blockage.
Solution: In order to reduce the occurrence of material blocking faults, the lateral dimension of the suspension bearing should be reduced as much as possible.

In addition to the above methods, it is also possible to install a silo level sensor and a blockage sensor to realize automatic control and alarm; increasing the discharge port or lengthening the end of the trough can effectively solve the problem of poor discharge, and it can also be used at the discharge A small section of anti-rotating vane is installed at the end of the feed trough. These can effectively prevent material blocking failure at the end.

The above are the reasons and solutions for the material blocking of the screw conveyor. If you have other questions to consult, please contact Henan Chunying Environmental Protection Equipment Co., Ltd.
