Concrete mixing plant troubleshooting

Screw machine feeding is very slow, feeding time more than 2 minutes, while the normal feeding in 20 seconds or less.

Analysis of the reasons: the main factors are poor powder powder and screw conveyor damage and so on. Powder off the poor performance of the form of powder from the arch, powder cans at the mouth of the material caking, the material butterfly valve opening is too small, powder tank material shortage. While the screw conveyor damage is mainly spiral blade deformation, can not be normal delivery.

Process:

1. Opening the gas blowing arch device.

2. Checking the powder tank discharge disc valve opening, and make the disc valve in full open position.

3. Checking the powder tank at the exit of the material is caking.

4. Checking the screw machine blade deformation, such as deformation is removed correction or replacement.
