    2015-6-19 · 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 matching mill required to draw this power Analysis of ball mill grinding operation using mill ,2014-3-1 · Siddique has presented data on dry grinding of 10/14 mesh limestone in 25.4, 38.1 and 76.2 cm diameter ball mills. The mill speed, ball load and particle load values corresponded to: (N: 0.6; J: 0.5; U: 1.0). Balls of four different diameters, 12.7, 19.05, 25.4 and 38.1 mm, were used for preparing the ball charge. The proportion of balls by number was: 36%, 24%, 26% and 14%, respectively.

    2012-2-7 · For the most productive milling operation it is often best to operate close to the maximum mill power draw. The power-load relationship is highly non-linear and shifts around as the ore and steel load/liner changes. Traditional control and modeling techniques can therefore not be used. Mintek has developed a Power Optimiser that:TECHNICAL NOTES 8 GRINDING R. P. King Mineral Tech,2009-7-30 · mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill power.
