Causes of Failure and Under Performance of Vibrating Screens

August 12, 2020

Vibrating screens are pieces of the machine that can efficiently segregate different kinds of materials. The separation of specific materials to others is possible with vibrating screens, which is mostly done in industries like mining, recycling, manufacturing, and construction. These screens serve as a substitute for the manual separation, filtration, or segregation of materials through various types of man-made screens.

However, just like other machinery pieces, vibrating screens can also fail and get damaged over time. The under performance of these screens is also possible due to various factors. Failure and under performance of vibrating screens are most likely caused by the following reasons:

Screen Openings

Failure and under performance of vibrating screens might be due to the existence of damages and holes on the screen mesh. As filtration processes happen continuously, the main screen mesh used for the activities may have been utilised for a long time now. Without any repairs and maintenance, this specific layer can easily accumulate damages or holes, which can ultimately affect the quality of the segregation process. Damages on the screen mesh can only be resolved by replacing it entirely.

Jammed Materials

The poor performance of a vibrating screen can also be associated with jammed thick materials on the machine. If both the water and mud content in the feed material is high, then they might suddenly latch into the sieve hole and block it entirely. As segregation continues, most products that need to be filtered are only stuck in the area where water, mud, and other materials accumulate. Cleaning the sieve hole can resolve the issue. Angle inclination of sieve or screen surface must also be adjusted.

Damaged Components

Failure and under performance of vibrating screens may also be caused by damaged components. If the spring and bearings found inside the machine are damaged, they will instantly produce some noise during operations that indicates their failing condition. Sieve parts, which include pipe beam, cross beam, and screen frame, can also get damaged. All these components may have been damaged due to a long time of use or lack of proper maintenance. Replacing all of them is necessary to keep the machine running.

Inaccurate Fittings

Loose bolts, untightened screen, and insufficient inclination are only a few of the things and elements that may have been fitted inaccurately. The first two mentioned problems can produce abnormal sound during operations and significantly affect the quality of filtration. The insufficient inclination of the screen surface can also result in poor screening output as the materials will not move or get processed easily. These components must be checked first so that the vibration screen can function optimally and effectively.

Knowing the causes of failure or under performance of vibrating screens can help you address them right away. And once you try to call for professional help, you can easily tell them the possible reason behind the malfunctioning vibrating screen.
