Modern mills operate with load cells and mill optimizer39s which synchronize the mill weight, power draw, ore feed and weight with density control. Where optimizers are not used, the rule of thumb for a overflow ball mill is a ball load up to about 12 inches below the trunnion discharge this allows bed expansion by the slurry filling the voidsGet Price
A Total Apparent Volumetric Charge Filling including balls and excess slurry on top of the ball charge, plus the interstitial voids in between the balls expressed as a percentage of the net internal mill volume inside liners. B Overflow Discharge Mills operating at low ball fillings slurry may accumulate on top of the ball charge causing, the Total Charge Filling Level to be

AMIT 135 Lesson 7 Ball Mills Circuits Mining Mill. For overflow ball mills the charge should not exceed 45 of the mill volume For grate discharge mills the charge should occupy about 50 of the mill volume Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge He and the radius of the mill R ie
Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8hour shift, allowing to calculate corresponding to circulating load

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.
We can calculate the steel charge volume of a ball or rod mill and express it as the of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. The loading or change volume can then be read off the graph below or
