Solution 1: It should be that some of the lining bolts are not tightly screwed. The solution is that you can judge the ball lining by the sound of the machine, then find the loose bolts and tighten them.

(5) The ball mill rolling bearing has too much or too little grease, and excessively formed rolling elements agitate the grease to generate heat, and the heat is not easily dissipated. If the lubrication is too small, the amount of oil should be increased according to the regulations, which is generally 1/3 to 1/2 of the bearing clearance.

PS: The above problems will be dealt with according to the reasons. Only if the side clearance of the bearing bush is too small, or the bottom contact angle is too large, the grinding cylinder body must be jacked up with a hydraulic jack, and the bearing bush is pulled out from one side of the shaft, and the tile is separately scraped.

Solution 4: adjust the wheel gap according to the specified, so that the two axes are concentric. Tighten the coupling bolts of the coupling symmetrically with the same torque. When the rotor is unbalanced, the ball mill rotor is taken out to find a static balance.

Solution 5: (1) The balance shaft of the ball mill and the reducer, the axis is not in the straight line, the reason is: when the mill is installed with the lining, no secondary grouting is performed, or the anchor bolts after the secondary grouting are not fastened, and the grinding cylinder is rotated by the hoisting machine, so that one end of the grinding cylinder is displaced, and the two axes are not in a straight line. The vibration is generated after the reducer drives the mill. To re-adjust, make the axis of the ball mill and the axis of the reducer on the same plane axis.

(2) The large ball mill is bulky and heavy, causing the foundation to sink; displacement occurs. Monitoring settlement points are set up next to the foundation; observations are made and adjustments are made when there is sinking.

Solution 6: The sound of the normal operation of the ball mill reducer should be even and stable. If the gear has a slight knocking sound, the hoarse friction sound, there is no obvious change during the operation, you can continue to observe, find out the reason, stop the ball mill and deal with it; if the sound is getting louder, you should immediately stop the ball mill for inspection.
