Liner wear model tracks liner and lifter state in the SAG or ball mill by modelling decrease in lifter height and angle across different liner sections in real time. The model uses historical information about liner wear to relate the wear rate with mill throughput and operating regimes.
It can predict the remaining life of the liner and aid timely replacement. Its outputs such as instantaneous liner mass and internal mill volume provide valuable information about current mill condition and efficiency and can be further used to model a typical ball trajectory or to correctly estimate mill charge in real time.
Below is one of the image form one of the dashboard with the model outputs :
