When to change ball mill liners?

Amongst many types of mill liners for grinding purposes, ball mill liners are at a league of their own. They have a unique structure that in turn gives them unique functionality, which reaps many benefits for us. Generally, it can be confusing to determine when we should change or replace them. In this article we shall explore what specific circumstances are required for us to change ball mill liners.

These mill liners are generally long lasting if used properly. There are some things to look out for that will give you an indication to change them. They are as such.

Decreased efficiency of the Mill

The ball is the fundamental component of the mill liner, which ensures the proper grinding process. Unless you have used a different and harder material, if the grinding process slows down or yields lesser output as compared to normal, it may be an indication that your ball mill liners may need a change because they may be internally damaged.

You should keep a track of your time period and output to keep a lookout. As soon as you notice the time and output getting to abnormal levels, you should immediately go for the replacement process, in order to ensure any structural damage to the overall mill.

Damaged lining of the barrel and ball mill

Among other things, these particular mill liners also prevent wear and tear. However, if during your regular inspections you begin to notice that the barrel’s and ball mill’s lining has begun to damage, it is a clear indication you need, or soon may need to replace the ball mill liner.

If you do not do regular inspection of these mill liners, you should start immediately, because it would be for the greater good of your mill and the employees.

More noise and impact

As it has been mentioned before, such mill liners also play a role in resisting wear and tear. With less wear and tear, you will hear less noise and feel less impact. It follows that if the noise becomes significantly louder as compared to before, and the impact starts to feel even greater than before, you may need an immediate change.

This is because with more wear and tear the linings get exposed, so as a result, less shock waves are experienced which means more impact will be felt outside. On the other hand, rubber as a material is noise resistant. If it wears off, you are exposed to noisy material that will ring your ears during the grinding process.

Final Thoughts

Manufacturers should look after their mill liners like they look after their own children. This is important because only through that they can ensure efficiency of their mills. If not taken care of and not replaced on a timely basis, eventually you will require more time, labor and cost in the repairing and replacing process. As they say, a stitch in time saves nine. Keep a check on your mill liners on a regular basis.
