This paper presents a case study, benchmarking actual plant data against ausgrind model predictions and validating the calculation improvements. Using austin's equation, the effect of relative percentage changes in mill rotation speed from 40 to 100% on consumed power and mill efficiency were calculated using equations 48 55, which are presented in table 18 and the graph in figure 10.

Power Consumption During Comminution On Five Disc Mill A Rice B This paper presents a case study, benchmarking actual plant data against ausgrind model predictions and validating the calculation improvements. Using austin's equation, the effect of relative percentage changes in mill rotation speed from 40 to 100% on consumed power and mill efficiency were calculated using equations 48 55, which are presented in table 18 and the graph in figure 10. The power based model, ausgrind, developed by ausenco (lane et al, 2013; chandramohan et al, 2018) was employed to predict the potential benefit associated with an improvement in cyclone performance to reduce the ball mill slurry superficial velocity and fully utilizing the ball milling power. Operating data from the single stage sag mill at anglo american’s el soldado mine in chile was evaluated and compared to four published power based comminution models. 2. metallurgical power requirements these are the equations based on the work by bond and rowland with autogenous power requirement based on the work by barratt. the equations work out the power required for the duty and are of an adequate form to provide to a mill supplier for final mill design. As part of this article, there are two ball mill calculations comparing conventional ball mill power consumption (hogg & fuerstenau model) before tramp steel removal (figure 14) and after tramp steel removal (figure 15).
