Abstract. In this study, the relationship between acoustic emissions and hardness of different rock types (model quartz, model calcite, and real iron ore) coupled with binary mix ratios of model quartz and iron ore (1:3, 1:1 and 3:1) was investigated in a laboratory-based AG/SAG mill. The acoustic emission response and sensitivity of the millof the mill data base with only a limited number of variables considered. 3.2 Rod Mill Design A different approach is taken with the rod mill design where equations by Bond and Rowling are used to calculate the mill power draw. The Morgärdshammar equation and the IMM equations are shown for comparison. The method of use is similar Grinding Mill Computer Model AusIMM

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 The harsh and hostile internal environment of semi-autogenous (SAG) mills renders real-time monitoring of some critical variables practically unmeasured. Typically, feed size fractions are known to cause mill fluctuations and impede the consistent processing behaviour of ores. There is, therefore, the need for continuous monitoring of Powders Free Full-Text Acoustic Sensing and Supervised

The technical and financial comparison «BM vs. VM», based on grinding test results, is not a problem. The comparison «SAG vs. HPRG» is more complex and requires the good knowledge of the entire grinding circuit and its phases, including the material classification and its handling. Round media in the SAG mill in such cases Research has consistently shown that AG/SAG grinding mill consumes most energy (30–50%), thus one of the critical operations in a typical mineral processing plant (Asamoah et al., 2021, Asamoah et al., 2019c, Ballantyne and Powell, 2014, Ortiz et al., 2020, Wu et al., 2020 ).

As one of the machines widely used in mining, a semi-autogenous grinding (SAG) mill can significantly improve the roughing efficiency of rock. But the SAG mill still faces the obstacles of significant energy consumption and empirical operation parameters. In order to obtain the optimal operation parameters of a SAG mill, in this paper, the Semi-autogenous grinding mills play a critical role in the processing stage of many mining operations. They are also one of the most intensive energy consumers of the entire process. Current forecasting techniques of energy consumption base their inferences on feeding ore mineralogical features, SAG dimensions, and operational variables.
