Vibrating screens are widely used in mining, chemical, building materials, metallurgy, electric power and other industries. The operating quality of the vibrating screen is very important to the entire production process, so the daily maintenance of the vibrating screen is very necessary.
Vibrating screen is a common source of noise. During operation, abnormal noises often appear. Moreover, it has high sound level, multiple sound sources, and complexity. How to solve the abnormal noise problem of the vibrating screen and effectively reduce the noise of the vibrating screen?
Causes and solutions of abnormal noise of vibrating screen
When the vibrating screen linear screening machine is running, once there is abnormal noise, it should be shut down immediately for inspection to avoid damage to other parts of the screening machine or even the production line shutdown. Generally, the inspection can be carried out from the following aspects:
When the vibrating screen transportation support is not removed, the transportation support should be removed immediately.
If the tie ring bolts are not tightened or the tie ring is not fully embedded, immediately tighten the nut or copper nut, and hit the tie ring with a wooden hammer.
The foundation of the vibrating screen is not stable and should be stable. The effect of using the rubber plate on the base of the vibrating screen is better.
The vibrating screen spring is broken or misplaced, replace the spring or reset.
The vibrating screen body and the discharge port are in contact with the hard objects and moved out at a distance greater than 0.5m.
If the fastening bolts of the vibration motor are loose, the bolts of the vibration motor should be tightened immediately.
The inlet and outlet of the vibrating screen should not be connected by a rigid connection, but by a flexible or cloth bag connection.
If the vibrating screen bearing is damaged, it should be stopped and replaced immediately.
When the vibrating screen beam breaks, it should be shut down immediately for maintenance and replacement.
