Ball mill liners are essential for enhancing the performance and lifespan of the ball mill. Mostly, it is lightweight and has high strength. This helps in decreasing torque requirements and stress on the mill bearings.
In this article, we have talked about everything you need to know about ball mill liner.
Application of Ball Mill
As far as the application of a ball mill is concerned, it is quite wide. It can be used in various industries like construction, metallurgy, mineral processing, and chemical industry.
The ball mill liner has a key role to perform and has a direct impact on the quality of the ball mill. The ball mill liner is installed to stop the cylinder from wearing
Uses of Ball Mill Liner
The main purpose of a ball mill liner is to protect the mill heads from daily wear and tear. Not only this, but it also helps in improving the grinding efficiency of the ball mill and increase their lifespan.
When it comes to the design of ball mill liner, there are several factors to consider. For instance, you have to consider the RPM speed of the mill, drilling pattern of mill heads, percentage of media filling, and grinding diameter of the media.
Ball mill liner is an excellent way to achieve an equilibrium between the lifespan and grinding efficiency of the equipment.
Moreover, ball mill liners are easy to install thanks to their handling system and filler ring.
Reasons for Wear of Ball Mill Liner
There are several reasons for the wear of a ball mill liner. Here are some of the most compelling reasons.
- If the ball mill liner installation is not correct, it will result in insufficient concentration. This will lead to rupture.
- The raw materials are of inferior quality that will reduce the time of liner used, leading to many problems.
- In case the design of the structure of the liner is unreasonable, it will cause uneven wear and tear. This means the lining will prone to wear and tear from the thin area.
How to Prevent Wear and Tear?
First, you have to choose a good steel ball and liner. The ball diameter must be of an appropriate size. If it is not reasonable, it will not prevent friction between the steel ball and liner. This will result in increased wear and tear.
The next thing you need to focus on is the material of the lining. You have to make sure the material offers high abrasion resistance. It will help in improving the wear resistance of the liner.
Another thing you need to pay attention to is the hardness of the steel ball. It is crucial that the hardness of the ball is low. Once you have operated the ball mill at low hardness for 2 months, you can switch to high hardness. This helps in increasing lifespan.
The installation quality of the ball mill liner is another factor that you must control. For instance, the steel ball and liner do not match, you should replace it. Once installation and debugging are complete, fasten the bolt. This will help ensure the ball mill liner is running smoothly.
