Vibrating screen noise control measures
1. Tighten all parts on the vibrating screen, especially the screen plate that needs to be replaced frequently, to avoid additional vibration due to the loosening of individual parts;
2. Replace the punched steel screen plate with a polyurethane screen plate or rubber screen plate with a small elastic modulus and low noise;
3. Add rubber plates to the side plates, feed inlet, discharge port and receiving chassis of the screen box, which can effectively suppress the high-frequency vibration of the side plates and reduce radiation noise;
4. Replace steel springs with rubber springs to reduce impact;
5. Add rubber plates to the side plates, feed inlet, discharge port and receiving chassis of the screen box, which can effectively suppress the high-frequency vibration of the side plates and reduce radiation noise;
6. Damping treatment is applied between the inner and outer sleeves of the bearing. The rolling element of the bearing can be made into a hollow rolling element or damping material can be added to the inside of the hollow rolling element, which can reduce the noise of the bearing.
Through these methods, the noise of the vibrating screening machine can be minimized to create a quieter environment for the work site.
