Home / Matchingmatching Mill Drum Size To Charge Volume
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
charge value to the initial size, by adding new grinding media), produces the increasing of the throughput of mill with 15 or even 30 % [1]. Taking in consideration the specified facts, it appears as necessary the control and adjustment of the specific charge of the drum with grinding media. For the mills with a
Rod mills normally carry 35 to 65% rod charge by volume. The limits on charge level are (1) keeping the feed end trunnion open so that feed will get into the mill, and (2) keeping the rod charge low so rods will not work their way into discharge openings where they can cause rod tangling.
This is a 2nd Method for estimation or measuring the steel charge volume inside a mill. If dealing with a full SAG/AG mill, this will give you the rock load%. If you can count liners, you’ll have your answer.

SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.
2015-06-19· The tendency of the charge to slip back along the rising side of the shell is reduced as charge level increases, until reaching between 30 to 40 percent of mill volume (in one particular test mill

The High Intensity Grinding (HIG) mill has been designed specifically to manage these type of complex, fine grained ore-bodies that are
The Outotec HIGmill comes in various drum diameters. The mill heights can be varied to optimize the media load and power input for specific applications. Chamber volumes range from 5 to 30,000 liters with corresponding drives from 5 to 5000 kW. The HIGmill is the only ultrafine grinding technology in commercial use that can use small-size high

measurement or the percentage by volume of balls in the mill. This is usually performed soon after a crash stop. The basic principle is to measure the height ‘H’ from the charge to the shell and the internal mill diameter ‘Di’. By calculating the ratio ‘H/Di’ and using the graph below (Figure 1), the charge filling degree in volume
How to Handle the Charge Volume of a Ball Mill or Rod Mill. Ball mill charge becomes measurably swollen only when there is a buildup of large unground material in the ball mill or when the density of the pulp in a wet mill is extremely high. Although these conditions are seldom encountered, it is recommended that ball mills be ground out prior
