The ball mill work index is con rmed at 16 kWht The operating work index though is in the range of 21 kWht to 25 kWht showing high inef ciency This raises the point that in some cases the Bond EF4 oversize factor calculation is not suf cient to compensate for the milling inef ciencies that arise
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 ball mill work index laboratory test is conducted by grinding an ore sample prepared to 100 passing 336 mm 6 mesh to product size in the range of 45150 m 325100 mesh thus determining the ball mill work index Wi B or BWi The work index calculations across a narrow size range are conducted using the appropriate laboratory work
