Analysis of noise and vibration during the operation of the ball mill

The ball mill is used for grinding materials after crushing, and CHAENG is a professional manufacturer of ball mill accessories, such as girth gear of ball mill, ball mill trunnion, ball mill end cover, etc., which are used by customers in various industrial fields. Ball mills are widely used in industries such as cement and building materials, especially for dry or wet grinding of various ores or other materials. After using it for a long time, there will be some noise or vibration. What is the reason?

When the ball mill is in operation, a regular tapping sound appears and the sound is loud. This is because some of the lining bolts are not tightened. When the ball mill rotates, the lining will hit the cylinder. At this time, the loose bolts can be found and reinforced according to the sound. Because the ball mill is in normal use, the sound produced by the operation is relatively uniform and stable. If the sound is getting louder, you need to stop the process for detailed maintenance.

Sometimes the speed reducer of the ball mill will cause a lot of vibration when it drives the mill, mainly because the axis of the balance shaft of the ball mill and the reducer is not kept in a straight line. The reason is that there is no secondary grouting when installing the lining, or the bolts are not tightened after grouting. During the overhaul, it is necessary to readjust and keep the axes of the two on the same line, and the vibration will be alleviated.

Regular maintenance of the ball mill, and maintenance indirectly determines its service life and operating rate. In order to reduce the safety hazard and ensure the normal operation of the ball mill, in addition to regular maintenance, it is necessary to carry out detailed inspections on important accessories such as ball mill trunnion, girth gear of ball mills, etc., and make records to ensure timely replacement and ensure employees Work safely.
