How to Resolve Common Vibrating Screen Problems?

June 23, 2021

Many industries utilise vibrating screens in their daily applications. What makes vibrating screens suitable to a lot of industries is that they can easily separate feeds that contain solid and crushed ores or products down to the specified material condition. The operations of vibrating screens are done by maximising the vibrating motion of their components and feeding the products through quality screens.

Although vibrating screens are mostly manufactured by reputable companies, they can still attain damages and issues throughout their service life. Fortunately, users of vibrating screens can easily resolve most of their problems. If you are currently operating with vibrating screens, then here are some of the most common vibrating screen problems and their accompanying solutions:

Failure to Start or Operate

Vibrating screens are expected to start once power is available. However, if they fail to operate, then you must check the condition of their vital electrical components. Additionally, you must assess if their vibration motor and other components are still in good condition or not. You must also confirm if the voltage that your vibration screens receive is sufficient. The presence of damaged electrical components, vibration motor, and other components means that they must be repaired or replaced right away.

Too Small Amplitude

Generally, the larger the material to be processed, the greater the vibration amplitude of the vibrating screen should be. Vibrating screens that have too small amplitude may mean that the material on their screen surface is too much. Moreover, the coupling bolt on the vibration exciter might also be detached. The grease found on the vibrating screens might have also become too thick. Both the screen surface and the vibration exciter can be cleaned and repaired to resolve this problem.

Abnormal Material Flow

Another issue that your vibrating screens may have is the abnormality in their material flow. There are numerous reasons behind the occurrence of this issue. For one, their screen boxes’ rigidity may be insufficient. They may also have loosened connecting bolt. The vibrating screens may likewise have an inaccurate horizontal level of the screen boxes as well as damaged screen mesh. The feedstock may, ultimately, be unbalanced. These possible causes of abnormal material flow can be resolved through thorough calibration and repair.

Damaged Components

If your vibrating screens have cracked side plate, broken beam, and damaged structural parts, then they must be checked right away. The working time of your vibrating screens at the critical frequency might be too lengthy. The weight error of the eccentric block may also be too large. Fortunately, these problems can be resolved by replacing the damaged vibrating screen components, tightening the bolts, and repairing the wall plate cracks.

Mediocre Feeding Quality

Maintaining optimum feeding quality for your operations is important. Hence, if your vibrating screens yielded poor feeding results, then their mesh may already be clogged, allowing fine particles and moisture to increase significantly and subsequently form a very thick layer on the screen. Cleaning the mesh can prevent particles and moisture from clogging its surface, improving your overall feeding quality.
