What should I do if the second-hand ball mill reducer is there?

　　The second-hand ball mill reducer has an abnormal sound. Under normal circumstances, the speed of operation is sluggish, and the noise is small. There is an abnormal sound. In general, the sound is relatively harsh, and similar problems are not easy to be excluded, continue to observe. Before solving the problem, the ball mill should do parking.When the second-hand ball mill is running, the sound of the rule beat the cylinder. It may be that the liner is loose, and when the cylinder is rotated, loose liner is copied back to the cylinder. This phenomenon cannot be avoided, a very fastened bolt before working, and loose will occur during high-intensity grinding. Therefore, after the mill is stopped, check the various components have no abnormalities.

　　There is noise when the reducer drives the mill, and the vibration is too large. Check if the second-hand ball mill is on the same straight. The above problems may be that the secondary grout is not performed during the mounting liner, or the fixing screw does not have a displacement. An abnormal vibration can be easily understood as a movement between the transmission and the drive objects without exercise on the same horizontal line. Due to the high working strength of the second-hand ball mill, the body shift and deviation are generally existent. Carefully check it in usual maintenance.
