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
[email protected]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

Ball Mill Loading dry milling When charging a ball mill ceramic lined mill pebble mill jar mill or laboratory jar use on a jar rolling mill it is important to have the correct amount of media and correct amount of product Charging a Dry Mill – The general operation of a grinding mill is to have the product impacted between the balls as
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
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
