Modelling S milling power and specific energy The ball charge is a function of the bulk fraction of the S mill volume (Jb) occupied by balls; the ore retained in the mill is the result of the volumetric filling which depends on the ore size distribution (specially the % +6″ and the % −6″ +1″), on the rotational speed (N/Nc) and on the solid concentration by weight fraction inside the

in empty ball mill power consumption is more or filled why. The maximum power draw in ball mill is when ball bed is 3540 by volume in whole empty mill volume Considering that ball bed has a porosity of 40 the actual ball volume is considered to be 2124 of the empty mill get an efficient milling action 80110 of the pores in the ball .

Jun 19, 2015 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 is calculated from known tables ‘the old fashion way’

United States power consumption is related to comminution (Comminution and Energy Consumption, 1981). With this in I mind it is understandable that one would want to control a grinding circuit so that the energy required to process a given ton of ore is optimal. .Furthermore, overgrinding an ore and the subsequent production of fines can reduce the

We have ore filling to power consumption in ball mills ,Mathematical models are presented which describe the power consumption in agitated ball mills in absence of grinding beads. In addition, tests with grinding beads filling were also performed, leading to scale‐up guidelines with respect to power consumption. Finally, the influence of size and material of grinding beads was investigated
