The cause of abnormal sound in the ultra-fine grinder

1.  Severe overload causes a heavy “humming” sound inside the ultra-fine grinder contactor.

2.  Due to poor contact or breakdown inside, the discharge point occurs, which is the “squeak” or “crack” sound inside the electromechanical disk of the traditional Chinese medicine ultra-fine grinder.

3.  Due to the loosening of some parts such as connecting bolts on the top cover of the ultra-fine grinder, the iron core of the traditional Chinese medicine ultra-fine grinding machine is not tightened, causing the vibration of the silicon steel sheet and making a strong noise. If the silicon steel sheets on both sides of the iron core are not tightened, abnormal noise will also occur.

4.  When there is a grounding or short-circuit fault in the power grid, a large current flows through the winding, and a strong noise will be emitted.

5.  When there are large power equipment or equipment that can generate harmonic current in the ultra-fine grinder, the startup of the large-scale ultra-fine grinding machine equipment or the operation of the ultra-fine grinding machine that generates harmonics may affect the transformer on the site of the ultra-fine grinder. Make a “wow” sound.

6.  Due to the ferromagnetic resonance, the transformer on the construction site will make an abnormal sound.

7.  If the primary side voltage is too high or unbalanced in the ultra-fine grinder, there will be a little sound.

8.  There is overvoltage, the winding or the lead wire is discharged to the shell, or the ground wire of the iron core is disconnected, causing the iron core to discharge to the shell, all of which are the discharge sound of the transformer on the construction site of the traditional Chinese medicine ultra-fine grinding machine.

When abnormal noise occurs in the transformer used in the ultra-fine grinder, the possible cause should be judged. Only when the ultra-fine grinder is well maintained can it work better.
