A ball mill is one of the most commonly used grinding machines in many industries. The material is crushed by the balls which are embedded in a container or a compartment. This type of grinder is also used for mixing and blending materials for paints, ceramics and pyrotechnics etc. For better functioning of a ball mill, it is crucial to understand the importance of different intricacies of a ball mill liner. In this article, you will learn about things that you should consider while replacing a ball mill liner.

To start with, for better results, the liner should be made up of alloys which are best suited to operating conditions in each plant, are cost-effective and have longer lifetime. However, in order to maintain the good performance of a ball mill, it is necessary to carry out the maintenance work regularly. Replacement of a ball mill liner is one of the things that need to be considered for better performance.

When to Replace a Ball Mill Liner?

You do not have to replace a ball mill liner regularly except under particular conditions. The ball mill will usually work for a long time without any damage unless the depth of lining wear is enough to have a serious impact on safe operation and efficiency of a ball mill. If depth of lining wear is serious, you should replace the ball mill liner as soon as possible. This is because a ball mill liner protects the barrel of a ball mill by reducing the friction of abrasive materials and body on it.

What Things Should Be Considered before Replacing a Ball Mill Liner?

Replacing a ball mill liner is not only a cumbersome task but also, a technical one which requires expertise and high-quality work. Before carrying out this task, you should always take steps for the safety of workers. Additionally, an appropriate ball mill liner replacement will increase the efficiency and working of ball mill for a long time. Moreover, it will also ensure the safety of ball mill.

1.    Consider the specifications of ball mill liner

Before replacing a ball mill liner, you should consider its specifications such as impact resistance, wear resistance, shape and material of the liner.

2.    Proficiency in operation

As mentioned before, replacing a ball mill liner requires both expertise and high-quality work. Therefore, you require a team under an expert’s supervision who know the installment requirements. In other words, proficiency is required in this operation.

3.    Suitable environment for replacement

It is necessary to have a suitable environment for replacement process. Good ventilation system along with suitable temperatures are crucial as the worker will have to enter the ball mill barrel for replacement process. In addition to it, you must circulate the remaining pulp in the ball mill, clean, dust and descale the entire cylinder in order to replace the ball mill liner.

4.    Pay attention to safety

Before removing old mill liner, you should remove the used lining screws. Furthermore, pay attention to the safety of workers so that they may not get injured by ball mill liner.

5.    Double check the inside and outside of cylinder

After replacing the ball mill liner, you should double check the inside and outside of cylinder to confirm that there is no working tools, person and other irrelevant things left in cylinder.

Even though replacing a ball mill liner is certainly not as easy task, however, it is indispensable for safe operation and efficiency of ball mill.
