The screw conveyor is mainly used for conveying cement and fly ash materials in concrete mixing plants. It has the advantages of small diameter of screw body, high rotating speed, large conveying quantity, high precision and good conveying condition.But after long time use, the problem of material blockage is also very troublesome, how it should be solved at this time?

Increase the discharge port or lengthen the end of the discharge chute to solve the problem of poor or late discharge.At the same time, a small section of counter-rotating blade can be installed at the end of the discharge chute at the discharge port to prevent the end from blocking the material.Strictly follow the operation rules to make no-load starting and no-load parking;Ensure continuous average feeding;Carry out necessary cleaning of materials entering the conveyor to prevent large impurities or fibrous impurities from entering the machine and causing blockage.

Install the level meter and blocking sensor to realize automatic control and alarm; Set up a anti-blocking valve on the cover plate of the discharge end. Minimize the transverse dimensions of the intermediate suspension bearing to reduce the possibility of blocking  when the material passes through the intermediate bearing.

The rotation direction of the rotary axis of the screw conveyor determines the conveying direction of materials. However, the general design of the screw conveyor is based on the single conveying to design the rotating blade.When the reverse transmission, will greatly reduce the service life of the conveyor.
