The Selection Design and Application of Mill Liners for
Mill Liner Wear > Monitor wear rates at frequent intervals mechanical gauge > Electronic measuring devices are also available Scanalyse > Liners could last 18 months so this is a slow optimisation process > Monitor cracks, damage bolts, pegging, broken balls,
A generic wear prediction procedure based on the discrete
Typical ball diameters range from 10 to 150 mm, thus weighting 1 g to 4 kg. Moreover, ball mills have on average a 4 m diameter and a 510 MW power consumption. As a result of the energetic motion of the balls, the environment inside of the mill is highly aggressive in terms of wear.

Figure 5. Highlow wave ball mill liner Materials The selection of the material of construction is a function of the application, abrasivity of ore, size of mill, corrosion environment, size of balls, mill speed, etc. liner design and material of construction are integral and cannot be chosen in isolation.

Optimization of mill performance by using SciELO
Optimization of mill performance by using online ball and pulp measurements. In the platinum industry, by increasing the solid content in the slurry, the product becomes finer. At a higher percentage solid than 73 to 74%, the product becomes coarser again. At this level, a drop in grinding efficiency occurs.
Using Abrasion Index for calculating Steel Balls and mill
Uniform ball distribution (Mixed size balls) is a must during starting of ball mill after liner replacement. Wt% solids in ball mill also play a major role. Operating variables its effect on ball wear Case study In 40 tph ball consumption was high, metallurgy of concentrates was less, difficult to
Grinding Media Lining Media Liner Wear Rate Modelling
Grinding Media Lining Media Liner Wear Rate Modelling Prediction also leads to the fairly generally accepted conclusion that the rate of wear is proportional to the power absorbed in a mill. Thus it appears that the ball wear is, very roughly, proportional to both rate of production of surface and to power input to the mill.
How to Reduce Steel Consumption in Grinding Mills
The way in which the mill liners tumble the ball charge determines how the balls will grind the ore and the liners themselves wear. Tumbling characteristics of the grinding media is determined by height, slope and radius of curvature of the liner surface. Hence the design of liners becomes an important factor in determining liner wear rate.

As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate The risk of underloading or overloading the mill is an additional factor A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is
