Mill Charge an overview ScienceDirect Topics

8.3.1 Rod Mill Charge. Rod mill charges usually occupy about 45% of the internal volume of the mill. A closely packed charge of single sized rods will have a porosity of 9.3%. With a mixed charge of small and large diameter rods, the porosity of a static load could be reduced even further.

CHARGING GRINDING MEDIA Grinding &

2021-7-7  During mill shutdowns, the mills should be periodically surveyed and the actual charge level observed. There is guidance in Moly Cop tools for doing this (spreadsheet: Media Charge level), where three methods are supported: Free height; Chord length; Number of exposed lifters; Charge monitoring. A control chart of mill power draw should be maintained.

Raw Material Drying-Grinding Cement Plant

Grinding media contain balls of different sizes in designed proportions with large sizes in feed end and small sizes in discharge end. About 27 to 35 % volume of mill is filled with grinding media. Equilibrium charge is that charge where compensation for wear can be done by balls of one size only usually the largest size in the compartment.

Variables in Ball Mill Operation Paul O. Abbe®

Considering a typical mill with a 50% media charge there will be 13% free space as a percentage of the total mill volume. About 10% more solids is added to assure that there is solids between the pieces of media available to be impacted as the media cascades. Generally a 50% media charge will require about a 25% solids charge.
