Methods of Reducing Noise of Vibrating Screen

Mining machinery working noise is generally larger, this has become a consensus, and noise not only affect the lives of people around, the operator's physical and mental health can also cause different degrees of damage. With the continuous development of mining machinery industry and progress, mining machinery and equipment noise reduction technology is also more and more advanced.

The working principle of the vibrating screen is by the motor shaft on the bottom of the installation of heavy hammer (uneven heap weight hammer), the motor rotation into horizontal, vertical, tilt the three yuan motion, then convey the movement to the screen surface. If you change the upper and lower parts of the hammer phase angle can change the direction of raw materials. The principle of vibration screening machine determines the vibration screen must be achieved through the vibration screening in normal work, but the vibration is the root cause of noise, and the sound level is high, the sound source and more complex.

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

First of all, should pay attention to whether is due to loosening of equipment parts caused by noise, therefore, noise reduction first to fasten all parts on the shaker, in particular, need frequent replacement of the sieve, to avoid the individual parts of the additional vibration.

Second, the early screen box side panels, feed to the material mouth, nesting material and then receive the material within the chassis rubber plate affixed to effectively suppress the side of the high-frequency vibration, reduce noise.

Again, with rubber springs instead of steel springs to reduce the impact, and the body outside the shaker to install soft acoustic enclosures, reduce noise.

Then, the bearing between the inner and outer damping treatment, the rolling bearing can be made into a hollow rolling body or in the hollow rolling inside the damping material, effectively reduce the bearing vibration and reduce bearing noise.

Finally, flexible web gear can be used instead of steel gears, that is, in the gear plate on the use of rubber elastic body to transmit torque, absorbing gear meshing, out of the vibration caused by.

There are many ways to reduce the vibration screen noise, the above is just the tip of the iceberg, if you have more questions about vibrating screen, please visit the official website of the zk corp consultation.
