The liner covering the inner wall surface of the drum of a grinding mill comprises a plurality of rectangular lining units each having an inner working surface inclined to approach the drum centerline from its upstream end to its downstream end, the lining units being in mutual dispositions such that lining units which are mutually adjacent in the drum rotational direction …
Liners for grinding mills having alternating bars of alloy steel and strips of an elastomer, such as rubber, bonded together and to a backing plate which is sufficiently flexible that the liner may be manufactured flat, but drawn against an arcuate portion of the cylindrical side wall of the mill by attaching bolts. Converging slots formed in the center bar of the liner are engaged by bolt ...
Dramatic shortcomings of mill liner designs, especially of large semiautogenous grinding (SAG) mills-such as rapid failure, mill shell damage arising from the charge impacting directly on the ...
The replacement of the mill liners determines the length of each concentrator shut-down. In other words, the liner lives and their replacement, define the time available for mineral processing. For every hour that the concentrator is shut-down due to liner exchange (Grinding Mill Relining) the mine site asset loses $50K to $500K per hour of ...

To prevent ore from wearing out grinding mill drums, replaceable liners are inserted. ABB and Bern University of Applied Science have developed a liner wear monitoring system based on accelerometers and machine learning that identifies the best time to change the liner and thus reduce downtime costs.
The liner contours are selected for the specific grinding application and take into consideration liner wear, scrap loss, and mill capacity. Liners cast of Manganese Steel, Ni-Hard, Chrome-moly, or other similar materials may be of the step type, block type, wave type, or the two-piece plate and lifter construction.
> Mill trajectory modelling based on bar heights, angles, spacing and speed is very predictive > Field trials are the acid test - operator, designer and vendor > Optimisation strategy: – Maximise impact grinding AG/SAG mills – Avoid impact on the shell rather the toe of the charge – Maximise liner life by protecting with mill lifters

Mill liners protect the mill shell from wear and transfer energy to the grinding charge. Careful balance is needed to optimise these differing requirements, as poor liner design has detrimental effects on milling performance – and on mill liner life. Mill liners developed by Multotec include Ball Mill Liners, SAG Mill Liners, AG Mill Liners ...
Installing replaceable liners in a grinding mill is not just a question of protecting the outer shell; the design of the liner and the materials used in its construction both play a critical role in the mill's performance. Use the correct material and an appropriate lifter design, and the mill will grind effectively.
We can design and supply mill linings for all types of mills - for Outotec mills as well as for competitor mills - and for all parts in the mill.

Description: The emphasis on liner design to ensure efficient mill operation has grown, particularly as mills have increased in size. The extent to which a liner effectively protects the mill, imparts energy and controls the mill charge, impacts on the total ownership . Industry & Application: Crushers & Grinding Mills, Mining, Pipes / Piping Material: Metal, Rubber / …
Every grinding mill lining application has different characteristics that require unique solutions to optimize mill performance and liner life. Mill liners have historically been made either of rubber or steel. Composite mill liners combine the benefits of steel liners with the flexibility of rubber liners.
There are basically two groups of Grinding Mill Liners. Ones with a HIGH PROFILE and those with a LOW PROFILE. The high profile liner is designed to give the media the higher lift. This type will be used in mills that are designed for primary grinding and as a result require the impact of the higher cascade.
The second primary function of a liner is to transfer rotary motion of the mill to the grinding media and charge. After all, it is the interface between the mill and the grinding charge. Although work on the grinding action in mills was published …
