How can we reduce the noise and sound insulation of the grinder
First of all you have to check as follows:
If the uniform noise is normal, the sound of the noise is different depending on the material being hit. If it is an abnormal noise, check whether the direction of rotation of the pulley is reversed. The high speed of the motor of the grinder makes the sound louder. Check the eccentricity of the internal rotor and whether the pulley is loose or elongated.
There are also two reasons: First, the bearings on both sides are worn and need to be replaced. The second is that the hammer is worn and the centrifugal force is inconsistent, causing the machine to shake and make the sound loud.
Second, whether the machine is running or the vibration is severe, you need to consider fixing the bottom with an iron pipe. Some people also say that it is not advisable to use a heavy object to press it and wrap it in a quilt. The machine needs to dissipate heat. It is recommended to be placed in a special soundproof room.
In many factories, the crushers are located in the crusher room, and multiple crushers work at the same time. The noise control of the crushers is carried out by sound-proofing the room.
1. For the grinder in the machine room, use brick-concrete walls to separate multiple grinders. For those without a machine room, a new sound-proof room is built and the noise of the crusher is reduced by using materials with a sound-absorbing and sound-proof effect.
2. Install sound-absorbing materials such as rock wool, glass wool, environmentally-friendly sound-absorbing cotton on the wall of the computer room and the wall of the partition wall to improve the indoor noise reduction effect.
3. Keep doors and windows in the computer room or soundproof room for maintenance and observation, and determine the number and size of doors and windows according to the number of equipment. Use sound insulation doors and windows to improve the sound insulation effect of doors and windows and avoid sound leakage from doors and windows.
4. The crushing machine room or the soundproof room should be equipped with a heat dissipation system. The operation of multiple equipment can easily increase indoor problems. High temperature will affect the normal operation of the equipment. The heat dissipation system includes vents and cooling fans. Install a muffler at the vent.
5. The equipment pipeline channel above the machine room or soundproof room should be filled with sound-absorbing and sound-proof materials to prevent equipment noise from leaking through the pipeline inlet and outlet on the wall.
The crusher and noise control are mainly achieved through the sound insulation, silencing and vibration reduction of multiple pairs of noise sources. Through various noise management, the noise of the crusher can be controlled to ensure the quietness of the factory environment.
