Ball Mill Liners Material Selection And Application

Material selection conditions Most of the ball mills used for cement production are tube mills with length diameter ratio L / d > 2.5. The mill has a coarse grinding bin and a fine grinding bin (some of which are three bins). The coarse grinding bin is mainly used for crushing and the fine grinding bin is mainly for grinding.

Looking for best material for a cryogenic ball mill cup and balls

I recommend alumina balls (not steel alloys though). I used ball mills in 5 ton capacity and pot mill in lab (250 grams) using alumina balls. I think alumina balls are inert (already oxidized) so that even though they may introduce some impurity, I don't believe this will affect your alloy chemically like Fe and Cr will.
