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

Apr 08, 2018 In general, therefore, the required mill power is calculated using the following equation. where n is the number of efficiency factors, EFi, used and fo is the feed rate of new ore to the mill. The power calculated from equation 2 can be looked up in published tables (Rowland and Kjos, 1978) and the correct mill

1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of ...

Calculation of Circulating Load in a Classifier. A mechanical classifier often receives its feed from a ball mill and produces (1) finished material which overflows to the next operation and (2) sand which returns to the mill for further size-reduction.

Apr 08, 2021 In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

Ball mill = coarse particles (in the plant ball mill) grinding efficiency Ore grindability (in the lab ball mill) The units of "ball mill grinding efficiency" will be covered in detail in the first part of the module. Alternatively, we can say that: Specific grinding rate = Ball mill x Ore grindability
