Evaluate the Current Condition of Your Vibrating Screens through Vibration Analysis

May 26, 2022

Mining, agricultural, and construction industries typically utilise vibrating screens to separate and transport refined materials to their intended locations. Without these screens, they may end up offering or using products with inconsistent texture and quality.

As their name implies, vibrating screens rely on vibration in conducting their operations. They possess vibration-generating components that can make their screen surface pulsate accordingly. Other components, alternatively, collect the screened materials for further processing or storage. While most of these components are made from durable materials, they must still be assessed periodically.

Assessing and evaluating the condition of vibrating screens are necessary to ensure that they can still perform optimally. If you currently maximise vibrating screens as your main equipment, you may want to evaluate their condition through vibration analysis.

An Overview of Vibration Analysis

Vibration analysis is the process of monitoring the levels and patterns of vibration signals within a component, structure, or machine. It aims to detect any abnormal vibration events, assess the condition of the object, and provide all the needed information for maintenance purposes.

Data from the vibration analysis can only be obtained once experts have investigated the patterns in vibration signals. This process is normally done both on the time waveforms of the vibration signal directly and on the frequency spectrum.

When conducting time-domain analysis, experts would extract and study the root-mean-square, standard deviation, crest factor, peak amplitude, skewness, and kurtosis. The gathered information will then reveal the severity of the abnormal vibration events and the instances of their occurrence. Frequency spectrum analysis, on the other hand, is done by decomposing time waveforms. The experts would then identify the repetitiveness of vibration patterns corresponding to the components that generate the vibrations.

Vibration Analysis Main Benefits

Vibration analysis offers tons of benefits to vibrating screens. These benefits include the following.

  • Prolong Service Life: One of the benefits of vibration analysis is it can provide the information needed in prolonging the service life of vibrating screens. With its accurate data, owners of vibrating screens can be provided with recommendations that could protect their components from damage. They can also be given some tips on how to use them more efficiently.
  • Boosted Productivity: Vibration analysis can also help vibrating screens to be more productive. A wide array of parameters is checked during this type of analysis. Once they have been analysed, experts can provide vibrating screen owners with the most optimal setting for their machines. Following their recommendations can easily avoid costly breakdowns and boost productivity.
  • Seamless Operations: One more benefit of vibration analysis is it can carry out the needed process without causing costly downtimes. Various vibration analysis tools can now be utilised by experts in collecting data without shutting down the vibrating screens. This benefit allows businesses to conduct their operations without expecting significant delays.
