The conveyor is mainly used for the transportation of materials. It has the point that the direction is changeable and the conveying direction can be flexibly changed. We commonly have screw conveyors and belt conveyors, etc. Among them, belt conveyors are the main way of conveying bulk materials. When we use or maintain the machine improperly, the conveyor may fail and cause downtime. Do you know the reason for the downtime of the conveyor?

Reasons for screw conveyor downtime

The screw conveyor has the advantages of small cross-sectional size of the whole machine, good sealing performance, multi-point loading and unloading in the middle, and easy operation and maintenance. It is suitable for conveying powdery, granular and small block materials. It is widely used in building materials, metallurgy, Chemical, electric power, coal, machinery, grain, food and other industries; it is not suitable to transport materials that are perishable, viscous, and easy to agglomerate.

The reasons for the stoppage of the screw conveyor are:

screw conveyor

1. The material is too large

Problem: The material to be conveyed is too large, the material cannot pass through the middle hanging bearing smoothly, and the material resistance at the middle bearing is too large, causing the screw conveyor to stop suddenly.

Solution: judge the size of the material before conveying to avoid the material being too large and stuck in the middle of the hanging bearing, resulting in downtime.

2. Material blockage

Problem: Blockage of material in the screw conveyor can also cause the motor to be overloaded and shut down.
Solution: We must clean up the material in the screw conveyor, keep the conveyor unobstructed, and install a belt cleaner to avoid blockage due to excessive viscosity of the material.

3. Seal damage

Problem: The resistance at the intermediate bearing is too large and the seal is damaged. Material entering the bearing causes the bearing not to rotate or the bearing is damaged.

Solution: The seal needs to be replaced, and the abnormality at the intermediate bearing should be checked for repair.

4. Bearing burnt

Problem: The reducer bearing is burnt, resulting in downtime.

Solution: Replace the new parts to ensure the normal operation of the machine.
