Analytic how to reduce the noise of the vibrating screen

Vibrating screen is a common source of noise, and the sound level is high, the sound sources are many and complex, how can we effectively reduce the noise of the vibrating screen?

1. It should be noted whether the noise is caused by loose parts of the vibrating screen equipment. Therefore, to reduce noise, * of all, all components on the vibrating screen must be fastened, especially the screen plate that needs to be replaced frequently, to avoid additional vibration caused by loose parts.

2. Rubber plates are added to the side plate, feed inlet, discharge port and receiving chassis of the early screen box of the vibrating screen to effectively suppress the high frequency vibration of the side plate and reduce the generation of noise.

3. Use rubber springs instead of steel springs to reduce shocks, and install a soft acoustic shield outside the exciter to reduce noise.

4. Damping the inner and outer sleeves of the bearing. The rolling elements of the bearing can be made into hollow rolling elements or damping materials can be added inside the hollow rolling elements to effectively reduce bearing vibration and reduce bearing noise.

5. You can use flexible spoke gears instead of steel gears, that is, the rubber elastic body is used to transmit torque on the spokes of the gears to absorb the vibration caused by the gears entering and exiting.
