SAG mills generate higher levels of impact reduction and ball mills higher levels of abrading action. A mill lining system serves two purposes: to protect the mill shell from wear caused by the impact and abrasion of the mill charge, and to elevate and tumble the mill contents in the necessary manner to create a grinding action. To achieve this ...
Dramatic shortcomings of mill liner designs, especially of large SAG mills, such as rapid failure and even mill shell damage arising from impacting of the charge directly on the liner, and unsuitable spacing of lifter bars yielding unfavourable compromises between lifter bar height and liner life have highlighted the significance of correct mill liner selection.
Alloys used for SAG mill liners should have impact and abrasion resistance [5,11,17]. Highcarbon Cr-Mo and low-carbon Cr-Mo steels are common alloys to produce SAG mill shell liners [17][18] [19]. ...
Rubber wedges in between and rubber lagging on the shell behind the liners provide protection to the mill shell. In our mills we specify steel liners with geometry to prevent slurry racing circumferentially, and minimise longitudinal gaps to prevent wedging by scats and slurry. In my experience, consistent gaps of between 10 and 12mm are the norm.

needs to respond to the process aspects of mill liner action that are critical to good SAG mill performance, i.e., the impact of shell liners on the grinding action and of grates and pulp lifters on pulp discharge. In recent years, the trend in large SAG mills has been to use wide-spaced shell lifters with large lifter face angles, primarily to

crushed ore. By the mid 1990s SAG mill ball loads had increased to 20 per cent and SAG mill diameters were increasing to 40 ft (Freeport, Cadia). A consequence of this was that the theory proposed by liner and mill suppliers that the number of lifters should be equal to (2 × mill diameter – 2) and that 12 degree

SAG mill A SAG mill is almost always a high-impact application. Hence, it is wise to use tough, impact-resistant materials that are somewhat softer but less brittle to avoid cracking, chipping, or breaking. Rubber/steel composite liners are often a good choice as is the range of more impact-resistant cast alloys. Rod mill As there should be very
Shell liner life is a crucial component in a mine's up-time, efficiency and output, and this this mine owner knows that not all mill liners are created equal. The solution In March 2018, FLS installed their Composite Shell Mill Liners in the mine's 24' x 14.5' SAG mill. The installation comprised
