4 Ways to Effectively Maintain Vibrating Screens

December 4, 2020

Vibrating screens are known to be one of the most important machines that are utilised in various industries today. They can efficiently separate different materials intended to be either processed again for later use or transferred to other facilities. These screens can likewise process either drenched or dried feed, making them extremely valuable when it comes to screening and feeding processes.

Generally, vibrating screens work for a reasonable amount of time just to carry out the screening process. They must, however, be maintained regularly to achieve optimal results. If you currently operate vibrating screens, here are 4 ways to effectively maintain their longevity and performance.

Conduct Weekly Checks

Vibrating screens are comprised of components that move and vibrate during screening operations. Hence, there might be some parts that might have been displaced. Others might even need some repairs or replacements after a long time of use. Checking the level of oil, stroke length and angles, as well as the bolts joints should be conducted every week. Additionally, assessment over the condition of screening media, wear parts, and springs must be done weekly. Upon these checks, you can eventually point out if some parts need to be replaced, repaired, or tightened.

Change the Bearings

One maintenance tip that you can do with your vibrating screen is to assess the condition of your bearings. Once you have found out that your bearings tend to overheat, produce unusual noise during operations, or obtain significant clearance between the outer ring and the rollers, then you have to replace them right away. Bearings tend to deteriorate pretty easily since they work alongside shock-type loads. The rotary motion of most bearings, likewise, can affect their longevity in the long run.

Replace the Screening Media

Just like the bearings, the screening media of your vibrating screens tend to receive a lot of workloads. With continuous usage of vibrating screens, some parts of it can eventually get damaged. All supporting bars of the media must be inspected for corrosion and visible damages. If you have spotted some warped or worn parts, then you must replace them as soon as possible. The capping/channel rubber must also be replaced alongside the screening media, ensuring that the screening process takes place optimally. All nuts and bolts that are integrated with the screening media must also be inspected and replaced whenever necessary. Tension plates or rails must also be replaced for appropriate tensioning.

Conduct Proper Welding

Excessive heating and welding the screen body of the vibrating screen is not recommended. However, there are cases where welding is necessary to keep the machine running before conducting maintenance. If welding is needed, you must assess and document first the reasons behind the occurrence of cracks before repairing them. You must also make sure that no elements will penetrate the surface of the bearings. Additionally, welding must be done on both sides of the plate. After conducting the needed repairs, you must now inspect the movement of the components and the stroke parameters before ordering for the needed replacement parts.
