for treatment . “ To become more productive and lower costs , this operation deploys highly sophisticated mill sensors and integrated control systems which defy conventional thinking in the comminution process . Acoustic sensors linked to infra-red imaging are used to control both the SAG and Ball Mill circuits .” reveals Dr Adair .
“ As a consequence , over the past five years the site has reduced absolute power consumption within their SAG ( Semi-Autogenous Grinding ) mill circuit by 26 %, while increasing throughput of material through the comminution circuit by over 35 %! In the process , they ’ ve also decreased consumables ( liners and grinding media consumption ) by 40 %. Best in class effective run time in mineral processing circuits globally is around 95 %. At MSC it is 97 %. In short , they have achieved substantial reductions in energy with increased metal production using conventional off the shelf technology . Why can this not be repeated elsewhere in the Industry ?” Furthermore , the site is located in an arid region of Bolivia , where access
