Force analysis. The main function of the ball mill liner is to protect the mill and use the convex peak of the liner to play the ball to grind and crush the material. Therefore, the main failure mode of the liner is abrasive wear under the repeated impact of small energy. Fig. 1 shows the motion diagram of grinding ball and material.

Design of cement mill liners There are several types of cement mill liners: feed-end-liners, lifting-liners, classifying liners.They all have some features in common.

An evaluation was made of the wear and performance characteristics of litter bars, and the cost-life effectiveness of backing materials for rotary-mill liners. In a large run-of-mine mill in which the litter bars were mounted on grid liners of austenitic manganese steel (AMS), the liners had an average life that was five to six times that of equivalent unprotected liners. For a single mill ...

The liners are from 50 to 65 mm thick (2″ to 2.5″) with the waves from 60 to 75 mm (2.5″ to 3″) above the liners. The replaceable lifter bar design made of either metal or rubber in about the same design proportions can be used. There could be a loss in power with rubber particularly if the mill speed is faster than about 72% of ...

Brunswick Mine SAG Mill Liner Design and Wear. Jan 01, 2003 · The mill operates in closed circuit with 0.66 meter horizontal cyclones to produce a ground product of 90 micron nominal size (K80).The AG/SAG mill liners are steel (Norsteel, chrome-moly steel) with rubber grates and rubber lined pulp lifters.The original liner design was based on studying other AG/SAG mills …

> Engineering approaches have highlighted mill performance with mill modelling and the use of improved materials > Liner design,with the advent of large diameter SAG mills, the issues of design, selection, monitoring and evaluation of mill performance is critical > Mill trajectory modelling can be used to great effect in improving liner design

Here is a home-made tool to measure or obtain a fingerprint of your SAG and Ball Mill Liner wear pattern/profile. Each time you shut down, get a profile and build a wear-life over time database to better predict your next reline job or monitor improvements to your liner design. ... Here is a great paper on The Selection and Design of Mill ...

Therefore, the selection and design of mill liners have always been of great concern to users. Function Design of Ball Mill Liners As one of professional ball mill liners manufacturers, we summarize the main functions of the three-point ball mill liners. It mainly involves the protection of the barrel and the control of the grinding medium.

This is particularly true in autogenous and semiautogenous mills. Critical mill and plant design factors should be considered while the mill and installation are still only "paper." Various current liner designs will be discussed ranging from lifter bar/plate to integral types. Modes of operation such as "high-low" will be considered.

To select the correct materials of construction, a combination of the applications' function, ore abrasivity, mill size, mill speed size of the balls and the type of corrosive environment need to be considered. Symptoms of poor liner design, which means your mill liner may require re-evaluation, include a noisy mill and broken mill liners.
