A mill power equation for SAG mills | SpringerLink · A mill power equation for SAG mills. L. G. Austin 1 Mining, Metallurgy Exploration volume 7, pages 57–63 (1990)Cite this article. 10 Accesses. 3 Citations. Metrics details. Abstract. Development of an equation for tumbling charge and balls plus comparison to plant data suggests that the net mill power for cylindrical semiautogenous mills can be calculated from {m_p} = .
A General Model for Semiautogenous and Autogenous Millingfor SAG and FAG mills, and gives the results of recent investigations of the physical processes occurring in autogenous grinding. The breakage process is treated as the sum of three regions of breakage actions: normal breakage caused by nipping of particles between media (steel balls or pebbles); abnormal breakage caused by media when the particle or lump is too big in relation to the media to ...

SAG Mill Optimization using Model Predictive ControlControl 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,, van der Westhuizen,, Mainza, 2009).
ONLINE SAG MILL PULSE MEASUREMENT AND OPTIMIZATION ... · Depending on the mill size the SAG mills draws between 2 MW and 17 MW. The product from the SAG mill is further reduced in size using pebble crushers and ball mills. Hence, typical gold or copper ore requires between and kWh per ton of energy to reduce the particle size. Considering a typical mining operation processes 10,000 to 100,000 tons per day the energy expenditure in grinding ...
A General Model for Semiautogenous and Autogenous Millingan 8 m diameter SAG mill with LID = grinding a copper ore, and predicted maximum capacity and minimum kWh/ton at about 6070 ball load at 25070 total filling. Two FAG mills of LID = 2 were necessary to give the same capacity, and the simulations indied a lower kWh/ton for these mills. For this ore, both systems were technically feasible.

Modelling SAG milling power and specific energy ... · This distribution affects the SAG mill load and the load affects directly the mill power and the efficiency of the mill operation (Van Nierop and Moys, 2001). If a SAG mill has been designed with a conventional power or specific energy model which do not consider the projected feed size distribution it is likely that this mill will reach the expected power consumption but will not satisfy the ...

(PDF) SINGLE STAGE SAG/AG MILLING DESIGN SINGLE STAGE SAG .The SAG mill was installed with a low ball charge, no variable speed and a fine grind was targeted (P80 106 µm). High circulating loads and difficulty achieving the target grind size were experienced. This type of ore should have been treated in a high ball charge SAG mill with variable speed capability.
SAG Mill Control Instability: Causes and SolutionsSAG Mill Control Instability: Causes and Solutions. Oscillatory unstable behaviour in a SAG mill is characterised by the mill constantly cycling between an overload condition and recovery from that condition by a substantial reduction in feed rate tonnes. Such behaviour is commonplace with SAG mills and gives rise to a significant overall ...
