Shell liners installed with the wear sensor was fitted into the selected mill, and system operated for 109 days after which the remaining thickness of the sensor and liner were measured and compared. During the operation, the sensor reading was continuously collected and reported.
Peening liners. The steel used to make the liners produced a significant amount of peening. This made liner removal a time-consuming activity and more hazardous activity, as a heat lance is needed to remove peened liners. It also increases the risk of structurally damaging the mill's shell. Pegging of the grate plates.
SAG and Ball Mill Liner system serves two purposes: 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, the mill liner profile must be constructed from high wear resistant materials and incorporate correct …

Liners protect the mill shell from wear and transfer energy to the grinding charge, and a careful balance is required to optimise these conflicting requirements.
Symptoms of poor liner design, which means your mill liner may require re-evaluation, include a noisy mill and broken mill liners. A noisy mill produces a distinct impact rattling, which indicates that the grinding media is impacting directly on the liner instead of on the toe of the grinding charge.
