The screening machine plays an important role in industrial production, but the noise it generates may have adverse effects on the working environment and operators. Here are some effective methods to control the noise level of the screening machine.

Firstly, optimize from the source of the device. In the design stage of the screening machine, low-noise motors and transmission components should be considered. For example, choose bearings with good quality and high precision, as low-quality bearings are prone to vibration and noise during operation. The new motor technology can also make the motor work more smoothly and quietly, reducing the generation of electromagnetic noise. And, design the structure of the screening machine reasonably to avoid resonance phenomenon. By precise dynamic calculations, the natural frequency of the screen body is shifted from the excitation frequency to prevent noise amplification due to resonance.

Secondly, effective vibration reduction treatment should be carried out on the screening machine. Install high-quality vibration damping pads at the contact area between the screening machine and the ground or installation platform. These vibration damping pads can effectively absorb the vibrations generated during the operation of the screening machine, thereby reducing the propagation of noise. For large-scale screening machines, spring dampers can be considered, which have good vibration reduction performance and can convert vibration energy into thermal energy for consumption. At the same time, flexible connections should be made to the pipelines and lines connecting the various components of the screening machine to avoid vibration transmission and noise generation through rigid connections.

Furthermore, sound insulation measures should be taken. Soundproof covers can be installed around the screening machine. Soundproof covers are usually composed of sound-absorbing materials and soundproofing materials, such as sound-absorbing cotton, soundproofing panels, etc. Acoustic cotton can absorb the sound emitted by the screening machine and convert it into heat energy, while soundproof panels can prevent sound from propagating outward. When installing the soundproof cover, ensure good sealing to prevent sound from leaking out through gaps. In addition, sound-absorbing materials can also be used to decorate the walls and ceilings of the workshop, which can further reduce the noise level of the entire workshop.

Finally, regularly maintain and upkeep the screening machine. Maintaining the good condition of each component of the screening machine is the key to controlling noise. Regularly inspect and replace worn parts such as screens, springs, etc. to ensure the normal operation of the equipment and avoid abnormal noise caused by component aging or damage. And, clean the equipment to prevent dust and debris from accumulating and affecting the smooth operation of the equipment, thereby generating additional noise. Through these comprehensive measures, the noise level of the screening machine can be effectively controlled, creating a quieter and more comfortable working environment.
