Vibrating mill generally adopts motor directly coupled device, which connection is simple and easy to maintain. However, if you can’t make the two connect well, you will cause the overall vibration.
1.The motor rotor and the crusher rotor of the grinding machine are in different axis. Now, you can move the position of the motor or add the pad under the motor to adjust the two into concentricity.
2.The reason why the two rotors are in different axis is that two support bearing surfaces are not in the same surfaces. In this situation, you can place copper at the bottom of bolster, or add adjustable wedge at the bottom of bolster to make sure the same axis.
3.Grinding chamber is vibrating largely. The reason is that the coupling and coupling misalignment rotor are out of the one axis, or the flat hammer is asymmetrical. In this situation, you can take the appropriate method withered entire coupling and motor connection depending on the type couplings: When the hammer is with different quality, it should be re-matched to each hammer, to make hammers be symmetrical, so that the relative hammer chip error is less than 5G.
4.Original balance is destroyed. You should do motor balancing test after repair to be done to ensure that the overall balance.
5.When grinder system's bolts loose, you should tighten anchor bolts to foundation while installing or maintaining. Also, you should install damping device to reduce vibration.
6.Hammer broken or crushed indoor hard debris, which will cause rotor imbalance and vibrations. Therefore, to regularly check for badly worn hammer of the grinding machinery is so necessary. In replacement, the parts should be symmetrical replaced; when occur a normal voice in the grinding process, the operator should stop the machine right now to check the matter.
