Mines (WA) 36ft SAG mill the number of Outer Head Liners was reduced from 36 to 18 pieces and in doing so reduced the time to replace them by 9 hours at a cost downtime saving of about U$25,000 per hour. In this case the liners sections are 3.5 t each. For smaller mills the liners have to be handled and installed manually, so smaller blocks with


The SAG mill liners wear will increase by 15% due to the impact of medium such as steel ball during the SAG mill operation. Later, people were inspired by the semi-automatic grinding mill, adjusted the amount of medium in the semi-automatic mill, and evolved our …


SAG circuits may employ low to relatively high ball charges (ranging from 2% to 22%, expressed as volumetric mill filling) to augment autogenous media. Higher ball charges shift the breakage mode away from attrition and abrasion breakage toward impact breakage; as a result, AG milling produces a finer grind than SAG milling for a given ore and ...


Figure 1 shows a schematic cross section of the Chadormalu iron ore complex SAG mill which consist of two rows of liners; (1) feed-end shell liners and (2) discharge-end shell liners. The present case study has been conducted on these well-worn liners. The liners were replaced after comminution of 800 thousand tons of iron ore.

Based on experience, mill-liner designs have moved toward more open-shell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of 2.5:1 and 5.0:1.


Mill liners provide the replaceable wear-resistant surface within grinding mills; they also impart the grind-ing action to the mill charge, and at the discharge end, remove the ground contents of the mill. In recent years, as SAG mills have grown in size, the process aspects of liner design and their impact on mill performance have
