Most mills can be converted from metal liners to composite rubber liners. These liners combine the best characteristics of metal alloys and rubber to obtain a superior design for use in AG/SAG, grate discharge, overflow ball mills and grinding ball mills. By using special alloy steel segments moulded into rubber, composite plates
SAG mill liners are different from ball mill liners. the diameter and input size of SAG mill is larger than ball mill. And the grinding media are more less than ball mill. The mining materials need to be a part of grinding media. That means the SAG mill should be hard enough to resist the impact from the mining rocks and not be yield or bend.
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

Feb 21, 2018 The SAG mill at the site grinds the gold ore which is then sent to the autoclave for further processing. The impact of steel balls against ore particles is an efficient grinding method, but it can also wear the liner that protects the cylinder.
Liner For SAG Mill. CIC is a leading comprehensive mill liner supplier for over 60 years and has won high approval from the global customers. The mill liners are used to protect the shell in order to avoid the impact and abrasion from the materials and grinding medium. Different types of mill liners can be used to adjust the movement of materials.
SAG mill liner development draws primarily on practical experience from SAG milling operations supported by computer-based modeling of charge motion in SAG mills and on established good design practice. Liner design needs to respond to the process aspects of mill liner action that are critical to good SAG mill performance, i.e.,
Jun 06, 2016 End and shell liner design in these mills is much the same as for SAG mills. The effect of liner design on performance is equally as important. For instance, in an iron ore operation using 6.4 m (21 ft.) mills, mill throughput was increased by 15 percent and power consumption reduced by 13 percent by liner redesign alone.

stresses in large SAG mills helped to drive the development of greatly improved liner materials. However, this cost engineering approach ignored the mill performance and overlooked the other key function of mill liners. The second primary function of a liner is to transfer rotary motion of the mill to the grinding media and charge.
