Some manufactures or retailers like to offer their liners in terms of gauges because they sound thicker than a true mil. To be technical, a 30 mil liner is equivalent to 0.0300 inches. A 30 gauge liner is equivalent to 0.0260 inches (26 mil). Therefore, if you see a liner advertised at 35 gauge, it is truly a 30 mil liner.

Without the use of appropriate liner measurement tools to track and quantify wear, an intentional increase in throughput and decrease in power draw with loss of liner profile as the conclusively identified root cause is difficult to validate. ... LINER SHAPE TRACKING MillMapper® provides high resolution three-dimensional mill liner thickness ...
Ball mills and grinding tools Cement ball mills are typically two-chamber mills (Figure 2), where the first chamber has larger media with lifting liners installed, providing the coarse grinding stage, whereas, in the second chamber, medium and fine grinding is carried out with smaller media and classifying liners.
When it comes to choosing a liner, the 20 mil thickness is typically the least expensive and on average normally lasts about 10- 12 years. An upgrade to the standard 20 mil liner would be the 28/20 mil liner and the advantage of this style liner would be you have the extra thickness 28 mil on the wall and 20 mil on the floor.

We offer fit for purpose liners for all types of mills, including SAG mills, AG mills, ball mills, rod mills, and pebble mills. Our liners are designed to fit the specific requirements of each mill, taking into account factors such as mill size, speed, charge, expected service life, and ore properties.
Ball mill Most ball mills, even in primary applications, have a finer ore feed size; this requires some impact but not enough to increase the media consumption or even break the liners. Typically, a ball mill lining has a more rounded profile, often like a sine wave, and the size of the waves is selected based on the size of grinding media used.
In practical terms, one must assume some mill diameter, usually about 150 mm (6 inches) less than the mill inside shell or nominal diameter, that allows for the difference between the mill inside diameter and the location of the centre of gravity of the ball, as well as an assumed liner condition midway between new and fully-worn.
Trelleborg shell plate liners are designed to complement the lifter bar operation for ball mills, rod mills and drum scrubbers. The thickness of the shell plate may be varied and optimized to match the time between overhauls or to modify mill capacity.
