capture high wear zones within the mill. Reline schedules can be optimized with confidence, the advanced forecasting algorithms capture dynamic wear rates over each liner lifecycle and historical data of several lifecycles can be compared to the current one. Quick and simple A mill scan usually takes between 15 and 30 minutes

Our ball mill liners are the result of state-of-the-art software-driven designs with industry-leading inspection data, achieving an optimal charge trajectory and rate of wear life for your ball mill. We ensure your ball mill liners are fitted with precise levels of workmanship, facilitating maximum mill uptime for increased production.
Mining companies can realize significant cost savings simply by slowing peak wear rate without compromising throughput, an outcome that calls for optimizing both the liner design and operating process parameters. Likewise, changes to the mill lifter design andor its operation can result in reduced power draw and therefore energy costs.
Ball Mill Liner, Rubber lining, Ripple liner, Mill liner wear Ball mill liner is used to protect the cylinder, so that cylinder from the direct impact of grinding and friction. Mill liner wear
Application of the proposed method in a 9.75 4.88m SAG mill indicated that the liner wear profile along the liner length is non-uniform and the highest wear occurs between 1.25m and 2.75m of the ...
high grinding media wear rate 1 200 gt. A new liner design was proposed to the plant in order to reduce media wear. This new design see Figure 13. Use of remaining stock of incorrect AG mill liners Correct ball trajectories and hence improved grinding efficiency and lower ball wear
primary mill. The liner design was retained resulting in very high grinding media wear rate 1200 gt. A new liner design was proposed to the plant in order to reduce media wear. This new design see Figure 13. New liner design left with AG liner right allowed for Use of remaining stock of incorrect AG mill liners Correct ball ...
movement of rocks and media in a dry ball mill based on the DEM 12. Xu Lei used the DEM method to predict the wear and impact of each part of the liners lifter bar 13. Zhen Xu used the DEM-FEM Finite Element Method coupling method to study the wear of the liner of the ball mill and analyzed the wear of four di erent surface liners 14.
Dec 01, 2010 2.2. Wear model description. The recent work of Radziszewski et al. 2005 reports that impact wear provides a negligible contribution to ball wear in SAG mills. Based on this it is proposed that abrasion wear provides the prime contribution to liner wear in primary and SAG mills.
Mill liner wear and life prediction for any linerlifter design SAG mill slurry pooling model to predict the onset and effect of slurry pooling for varying operating conditions Grinding mill trajectory model to determine safe operating speed ranges based on linerlifter design
ball mills have been also modelled using the DEM. The motion of steel balls was affected by the type of feed and the friction of the media Rosenkranz et al., 2011. Sato et al. 2010 tried to relate wear to the impact energy of steel balls of a planetary ball mill. They found that wear rate

Due to the nonuniform liner wear profile along SAG mill the mill length the lifter angle face for any given operation hours varied significantly. For example, the largest change in the lifter A typical 3-D model of a worn liner after 5384 h of operation is angle face for the operation hours of
MillMapper shows wear patterns on liners and lifters through color coding. While knowing when to change worn mill liners can be a challenging task, Outotec claims that its MillMapper 3-D laser scanning technology can help to reduce downtime and liner costs, and improve overall grinding efficiency. In order to optimize running costs, grinding mill operators and maintenance crews need to be sure ...
Liners in bigger mills wear out quicker, often only after a year or so, whereas liners in smaller mills are still useable after two-to-three years. Because of this, there is more demand for replacement liners from big mills, which means that companies have to get these in stock ahead of time, said Kumar.

Wear-resistant liners board includes applied in various types of ball mills Overflow grinding mill,Cement grinding mills, SAG mill, Feed head of AG mill, Discharge head and Shell liners which used in non-ferrous metal mines and iron ores such as copper mine, molybdenum mine, copper-cobalt mine, gold mine and iron ore field.And various types of cone crushers and high manganese steel liners.
Highlow double wave ball mill liners These are a refinement of the wave liner, Figure 5. This was applied to Cadia Hill Gold Mine through evaluation of their existing wear profile and wear rate, and provided a more consistent wear profile through the liners working life.
Lifter Bar. Liner Plates is one of the most important parts of ball mill, so far most of the liner plate has lifter bar to improve the lifting force of the medium to achieve the best promotion effect.Lifters are an essential element in the tumbling action of a grinding mill,
Lower wear rate of mill liners and grinding media. Higher percentage of fines in mill product. In many cases this is very desirable. Target Grind Size. Another factor in choosing a grinding mill is the consideration of the feed size introduced into the mill, and the product required from the mill or mill

Simulated breakage rates for a copper ore as a function of particle and steel ball size for a ball mill top and DEM median impact energy and collision frequency as a function of ball size bottom, where M b is the mass of the ball charge 30 mill filling and 67 of critical speed in a 0.3 m diameter mill.
ore to ball mill feed. In recent years, the trend has been towards larger-sized SAG mills with diameters of 10.4 m 34 ft and above, with the largest being 12.2 m 40 ft in diameter and drawing 20 to 22 MW Jones, 2006. Mill liners provide the replaceable wear-resistant surface within grinding mills
helps understand charge motion in SAG mills for the given liner designs and lifters, ball size and rock properties, and mill operating conditions. Based on the success of the 2-D model of the SAG mill, the 3-D model in DEM was developed. These types of models could help study charge motion, power draw, liners wear, and energy draft
This ensures that the liner is appropriate to the mineral being processed as well as its wear rates. Our SAG mill liners are custom designed to your application requirements. In applications that feature large ball and feed sizes as well as with large mill diameters, Multotec supplies MultoMet or HD MultoMet SAG mill liners and heavy-duty ...
