Faults and Solutions of Screw Conveyor

Online, April 29, 2014 (Newswire.com) - Screw conveyor is an ideal machine to convey materials in food processing industry, which relays on blades rotation in groove to propel materials forward. when materials are feed into groove, they will be conveyed the discharging outlet along the screw, and consequently achieve process of conveying with quick speed and high efficiency.

Advantages of Screw Conveyor

The screw conveyor has the functions of compact structure, the smaller occupied area, the easy to seal for avoiding dust to access to drop into interior, so it is best suitable for powdery materials and bulk materials. Due to adopting adjustable controller, the feeding accuracy is also controllable to widely apply in food producing line.

Faults and Solutions of Screw Conveyor

1. The conveying throughput reduction obviously.
If this condition come out, the more possible reasons are root in spiral itself, the three reasons are classified into blades consistent, blades wearing and body blocking. We can adjust blades angle to reach coincidence, or maybe change the screw body, and reverse screw shaft for clearing off the materials blocked into screw body.

2. The leakage of materials.

The leakage of materials will wast our production cost directly, so this state is critical to solve it. When we check the cause of this state, the sealed components is the first to check. If it is true, and thereby, the changing seal and seal gasket is not avoidable.

3. The rotary shaft heating up to more than 30Ўж.

Rotary shaft is rather important for screw conveyor, which play a supporting machine rotary body to low friction during driving process. Provided that the shaft has problems, which will bring about rather worse influence on machine itself and producing itself. So when similar condition rise, the first what we do is check reasons. The most likely reasons for this fault are shaft itself, the seal, the lubrication.the relative solutions are complementing lubricating oi, clearing up seal and changing shaft.

4. Stacking material in feeding inlet.

All powdery fragment and granular are not applicable for food grade screw conveyor, there is not suitable for higher moisture content, Bulging features stronger and Large pieces of material. And in addition, the feeding materials must be evenly and uniformly. At the same time, it does not allow to knock at feeding hooper.

From above mentioned information, we can draw a conclusion that it depends on different states for different repairs and maintenance in our food processing process.
