The screw conveyor can transport particles, powders and small blocks, etc. There are many types of conveying, such as horizontal conveying, inclined conveying, vertical conveying, etc. The conveying distance can range from two meters to seventy meters. Blocking is one of the most common types if it is prone to failure or improper maintenance. Why is there a blockage? How to solve the problem of blocking material?

The reason for the easy occurrence of blockage failure is that the operator does not operate strictly according to the operation specifications. When the operator starts, there is no load, the feed should be uniform, and the conveyor must be stopped when no load is carried out, and the operation cannot be carried out at no load. A vibrating feeder can also be installed evenly. In the feeding process, if the material is suddenly added, it is easy to produce blocking materials, and the wear of the conveyor will be increased. Therefore, the feeding process is gradually increased, and the rated conveying capacity is gradually reached.

When selecting a screw conveyor, it is necessary to consider the conveying material, the conveying amount, the rotation speed of the conveyor, the 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 block the material. Therefore, careful consideration should be given when selecting a conveyor. It is necessary to select and transport the material to achieve a matching effect.

When the screw conveyor conveys the material, there must be impurities in the machine. If the necessary cleaning is not carried out, the residual large impurities or fiber impurities may cause blockage. Therefore, in order to reduce the occurrence of the blockage, the inside of the machine should be carried out when conveying the material. Clean up.

The bearing of the conveyor is the most prone to the problem of material blocking, so to reduce the occurrence of blocking failure, the lateral dimension of the suspension bearing should be minimized.

In addition to the above methods, it is also possible to install the silo level positioner and the clogging sensor to realize automatic control and alarm; increase the discharge port or lengthen the end of the trough, which can effectively solve the problem of poor discharge, and can also be used at the same time. A small section of the reverse rotation vane is mounted at the end of the material chute. These can effectively prevent the blockage failure at the end.

If a tubular screw conveyor is used, a valve can be added to the discharge end so that once the door is blocked, the door can be opened to clean the material.
