Calculating Power Draw when sizing Ball Mills Grinding I believe that as circulating load in a ball mill increases beyond a critical point the mill power draw begins to fall so there is an adverse effect on grinding efficiency (apart from the obvious physical problems it

To that end, it is usually necessary to enter the confined space of a grinding mill, a task that involves a degree of safety risk and a potentially lengthy plant stoppage. This paper discusses a range of available methods for measuring and calculating mill filling and introduces a new technique for accurately measuring filling that eliminates the need to enter the mill in most cases.

· Mill filling has a dominant effect on grinding mill performance (Apelt, Asprey and Thornhill, 2001), and therefore, its accurate measurement is vital for modelling grinding mill performance. Measuring filling is also necessary to estimate the composition of the load for mill modelling: rock and slurry for AG mills; rock, balls and slurry for SAG mills; or balls and slurry for ball mills.
