Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and ...

Mill capacity can be increased by increasing speed but there is very little increase in efficiency (i.e kWht-1) when the mill is operated above about 40-50% of the critical speed Please join and login to participate and leave a comment.
