While themillis stopped, thecharge volumecan be gotten by measuring the diameter inside the liners and the distance from the top of thechargeto the top of themill. The % loading or change volume can then be read off the graph below or approximated from the equation andcalculation: %Steel Charge LoadinginMill= 113 – 126 H/ D
[email protected]For overflowball mills, thechargeshould not exceed 45 of themill volume.Forgrate discharge mills, thechargeshould occupy about 50 of themill volume.Bond developed a relationship that can be used to determine the percentchargeby volume as a function of the vertical height above thecharge, he, and the radius of themill, r, i.E.,.

Effect of Friction of the Wall on theChargeProfile. A smoothly linedmillconsisting of 24 elements (walls) with 45%ballfilling was simulated. The behavior of thechargewas studied by changing the coefficient of friction at the wall. Three different disc sizes of equal proportion were used. Themillwas rotated at 63% of the critical speed.
