High noise levels in linear vibrating screens can be problematic, affecting both the working environment and the longevity of the equipment. Here are some common reasons for high noise in linear vibrating screens and potential solutions.

Reasons for high noise of linear vibrating screen

1. Loose or Worn Parts


Loose bolts, worn-out bearings, and other components can cause excessive vibration and noise.


Regularly inspect and tighten all bolts and fasteners.

Replace worn-out bearings and other components promptly.

2. Poorly Designed or Maintained Springs


Springs that are not properly designed, installed, or maintained can lead to uneven distribution of vibration and increased noise levels.


Ensure that the springs are designed to handle the load and vibration frequency.

Check the condition of the springs regularly and replace them if they show signs of wear or damage.

3. Imbalance in the Vibrating Motor

An imbalance in the vibrating motor can cause uneven vibration and increased noise.


Balance the motor by adjusting the counterweights or replacing the motor if necessary.

Regular maintenance checks can help identify imbalances early.

4. Inadequate Damping


Insufficient damping materials or mechanisms can result in higher noise levels as vibrations are not adequately absorbed.


Add or improve damping materials such as rubber pads or isolation mounts.

Use sound-absorbing materials around the screen structure.

5. Excessive Feed Rate


Feeding material at a rate higher than the screen’s designed capacity can cause excessive vibration and noise.


Adjust the feed rate to match the screen’s capacity.

Use feeders to ensure a consistent and controlled feed rate.
