1. Fixing the vibration motor iron plate: The vibration motor itself produces little noise. However, when there is a problem with the design angle between the vibration motor and the motor plate, it can cause vibration deviation in the entire vibrating screen. Firstly, small-area cracks in the weld joints can generate noise. Secondly, if the material and thickness of the fixed vibration motor iron plate are not up to standard, the motor iron plate may become distorted after prolonged use, causing cracks in the screen body and generating noise. Therefore, the material and thickness of the fixed vibration motor plate are very important

2. Screen body screws and nuts: All components of the rotary vibrating screen are assembled through the connection of screws and nuts. For new equipment, it is recommended to run-in for about 10 hours and then retighten the screws and nuts of the entire screen machine. Loosening of components such as the screen mesh, screen frame, vibration motor, retaining ring, and anchor nuts can all generate noise

3. The quality of materials used for the bouncing ball and rubber ring can also affect noise generation. Some materials are harder and have stronger wear resistance, which can produce noise during vibration of the screening machine. Users should choose appropriate materials based on the situation. It is recommended to primarily select silicone materials, which have advantages in terms of bouncing force, wear resistance, and noise prevention

4. Attention should be paid to the flatness of the ground for the rotary vibrating screen. Before installation, a special tool must be used to measure whether the ground is flat. If any issues are found, they should be rectified in a timely manner. Operating the screen on uneven ground for a long time can affect the structure of the screen
