## Calculation Of The Power Draw Of Dry

of the Bond ball mill grindability test. For all model based methods a reliable method to calculate mill power draw for a given mill is required for the calculation of power draw. Morrell 1996 proposed a mathematical model for autogenous semi-autogenous and ball mills which is based on the motion of grinding charge inside the mill.

## Ball Mill Designpower Calculation

Apr 08 2018 Example Calculation. A motor with around 1400 Horse Power is calculated needed for the designed task. Now we much select a Ball Mill that will draw this power.. The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. The following shows how the size or select the .

and ball mills have almost become obsolete in the move to higher milling rates required to process lower metal grades. Grinding circuits with fully autogenous AG or semi-autogenous SAG mills often combined with ball mills are now the standard to meet the high capacity requirement for processing ores with lower metal grades.
