Causes and solutions for the blockage of screw conveyor

Screw conveyor is a relatively common conveying equipment. It is generally a relatively small conveyor that can be combined with a vibrating screen. However, in some cases, the screw conveyor may be unloaded or blocked. What is going on here? How to avoid this kind of problem? Let me have a look at it now!

1. Clean the materials in the screw conveyor

We need to clean the materials entering the conveyor to prevent large amounts of impurities or fibrous impurities from entering the machine and causing blockages. We should reduce the lateral 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.

2.Install anti-blocking valve

We open an anti-blocking valve on the discharge end cover. If a blockage occurs, it is due to material accumulation, and the door is opened to prevent the door from being blocked, and the power is cut off by the stroke switch.

3.Install material blocking sensor

Automatic control and alarms are required when we install the silo leveler and block the sensor. When using a screw conveyor, we should pay attention to the above problems, so that the phenomenon of blockage will be greatly reduced or even not occurred, and our production and use will be unimpeded.

4. Choose the right screw conveyor

It is reasonable to choose various technical parameters of the screw conveyor, if the speed of the slow screw conveyor can not be too large. We need to increase the discharge port or lengthen the end of the trough to solve the problem of poor discharge and time to discharge. At the same time, a small number of reverse-rotating blades can be installed at the end of the discharge chute to prevent the end blockage, which also has a certain effect on the life of the lifting screw conveyor.

The shaftless screw conveyor has strong anti-winding ability. Because there is no shaft in the center, it has great advantages when transporting some easily entangled materials. It is often used for domestic garbage and organic plant transportation. However, when used, the damage of the blade is often found.

The above is a solution for screw conveyor blocking, hope to help you, you can also directly consult us, we have professional technical staff to answer your questions.
