How To Effectively Maintain A Vibrating Screen?

Nov. 09, 2021

Vibrating screens are known to be one of the most important machines used in various industries today. They can effectively separate different materials for reprocessing for later use or for transfer to other facilities. These screens can also handle soaked or dried feed and are therefore very valuable in the screening and feeding process.


Normally, vibrating screens will work for a reasonable period of time just to perform the screening process. However, they must be maintained regularly to achieve optimum results. If you are currently using a vibrating screen, here are 4 ways to effectively maintain its life and performance.


Carry out weekly checks

A vibrating screen consists of parts that move and vibrate during the screening operation. Therefore, there may be some parts that may have shifted. Others may even require some repair or replacement after extended use. The oil level, stroke length, and angle as well as the bolting should be checked weekly. In addition, the condition of the screening media, wear parts and springs must be assessed on a weekly basis. With these checks, you can eventually indicate whether certain parts need to be replaced, repaired, or tightened.

Replacing the screening media

Just like the bearings, the screening media of a vibrating screen tends to take a lot of work. As the vibrating screen continues to be used, some parts of it will eventually be damaged. It is important to check all support rods of the media for corrosion and visible damage. If you find some warped or worn parts, then you must replace them as soon as possible. The lid/channel rubber must also be replaced together with the screening media to ensure that the screening process is carried out in the best possible way. All nuts and bolts integrated with the screening media must also be checked and replaced if necessary. The tensioning plates or guides must also be replaced for proper tensioning.


Replacing bearings

One of the maintenance tips you can perform with your vibrating screen is to assess the condition of the bearings. As soon as you notice that the bearings tend to overheat, that they make unusual noise during operation, or that there is a large gap between the outer ring and the rollers, then you must replace them immediately. Bearings tend to deteriorate easily because they work with shock-type loads. In the long run, the rotational movement of most bearings will likewise affect their service life.

Carrying out the correct welding

Excessive heating and welding of the vibrating screen body are not recommended. However, welding is sometimes required to keep the machine running until maintenance can be carried out. If welding is required, you must assess and document the cause of the cracks before repairing them. You must also ensure that no elements will penetrate the bearing surfaces. In addition, welding must be carried out on both sides of the plate. After carrying out the necessary repairs, you must now check the movement and travel parameters of the assembly before ordering the required replacement parts.


In order to satisfy the market demand of large capacity, high vibrating strength, and high reliability, Anshan develops the GJZKK series large linear vibrating screen. It is mainly used in dry and wet separation of medium and fine size material and also dewatering, remediating, desliming, and so on. The linear vibrating screen has a large capacity, high screening efficiency. It saves occupation and is more reliable and easier to maintain compared with a common type of screens group to reach the same capacity.
