Mar 2, 2017 · Successful control of Semi-Autogenous Grinding (SAG) mill circuits has been the subject of many researches and main concern of plant operators for years. Distributed Control Systems (DCS) have had some degree of success in the mineral processing circuits, but maintaining operation of a SAG mill on the “edge” of its full capacity is not ...

Mar 15, 2024 · that a slightly more expensive 42 ft SAG mill with equivalent power to the 40 ft SAG mill enhanced the project economics. After assessing the potential reliability difference between the 40 ft SAG mill and the equivalently powered 42 ft SAG mill, Newmont made the decision in 2010 to purchase a 42 ft SAG mill from Metso and a 28 …
This paper reflects on how measurements from inside an operating SAG mill might be used to better understand charge motion and energy dissipation within the mill. The paper discusses how the measurements might influence and enhance approaches to energy efficient mill operation when compared with current day modelling techniques. Insights …

Jan 13, 2022 · However, the objective of how many mass that the mill can process is limited. Some conditions, such as excessive ore volume, composition, particle size distribution, hardness, underestimated spin speed, incorrect percent solids, among others, can lead to overload. Exists three types of overloads can occur in a SAG mill (Fig. 1). …

Control of -SemiAutogenous Grinding(SAG) mill weight is an example of an important process that exhibits many of these aspects. Maintaining the SAG mill weight at the optimum value is critical for achieving maximum grind rate efficiency and mill production (Powell, M.S., van der Westhuizen, A.P., & Mainza, A.N. 2009).
