Optimization of operating conditions on ultra-fine coal

网页2022年5月1日  Introduction Grinding circuits have always been a crucial part of mineral processing operations. Although it is possible to achieve a good liberation with conventional grinding approaches, ultra-fine grinding has become increasingly more critical over the years with increased fine-grained ores and the depletion of high-grade deposits [68].
