It is common view that there is large noise of the mining machinery working. Noise not only affects the lives of the surrounding people but also causes varying degrees of damage to operator's physical health. Nowadays, with the rapid development of miming industry, the equipment noise reduction method is more and more advanced. Now I will introduce the noise reduction method of vibrating screen in the following paper.
First of all, you need pay attention to noise caused by the parts loosening. Therefore, it is necessary to fasten all parts on the vibrating screen, especially the screen plate replaced frequently, avoiding the extra noise caused by parts loosening.
Secondly, paste rubber sheet on the feed inlet, discharge port and splice tray, effectively suppressing the frequency vibration of side plate and reducing noise production.
Thirdly, replace steel spring with Rubber spring to reduce impact force. Install soft vibration isolator on the exciter to reduce noise.
Fourthly, damped treatment is necessary between the inner and outer bearings. You can also make a hollow roller to effectively reduce the bearing vibration and bearing noise.
At last, use flexible web gears to replace the steel gears; it means that the torque is transmitted by the rubber elastic body on the gear web plate absorbing the vibration caused by gear engaging-in and engaging-out.
There are many ways to reduce the vibration sieve noise; the above-mentioned ways are just the tip of the iceberg. If you have more questions about the vibrating screen or mining machinery equipment, welcome to consult the official website of Fote Machinery for further understanding.
