How Mill Load/Charge is Estimated Grinding & Classification Circuits
Modern mills operate with load cells and mill optimizer's 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 voidsAMIT 135: Lesson 7 Ball Mills & Circuits Mining Mill Operator ,Ball Size as Initial Charge Commercial ball sizes 10 150 mm Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., d↓V = 0.40 K√F
MODELLING THE INFLUENCE ON POWER DRAW OF THE
The slurry level in AG/SAG and ball mills has an influence on their power draw, which in some instances can be profound. This is particularly the case with socalled slurry pooling in slurry. The density of the rock/ball charge (ρm) is estimated using the following equation : ρm = ((JtJb)*ρo + Jb*ρb)/ε (2) Where, Jt = total fractionalSimulation of overflow ball mill discharge and trommel flow using,91· Rob Morrison The University of Queensland Discharge of pebbles, finer rock, ball scats and slurry from mills and its flow through trommels, and into other processing operations has strong.

Effects of slurry pool volume on milling efficiency ScienceDirect
201441· A laboratory mill, filled with 20 mm balls, was used for the tests. Two levels of ball volumetric filling were considered: J = 20 and 30%. Slurry filling U was varied from 1.5 to 3.0 with reference to 20% ball filling. Equal masses of slurry were also used for a 30% ball filling which made slurry filling U change accordingly.Method to Determine the Ball Filling, in Miduk Copper ,At the time of this research, mill ball charged, feed rate, and average moisture were 7 tons (ball size was 100 mm) per week, 720 t/h and 5%, respectively. Then, ball abrasion rate was calculated by Equations 4, 5 and 6. Total mill feed per week = 720*24*7*0.95= 114912 tons Total ball charge per week = 7*106 g (4) (5)
