Ball Mills - an overview ScienceDirect Topics

In general, ball mills can be operated either wet or dry and are capable of producing products in the order of 100 μm. This represents reduction ratios of as great as 100. Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity.

Ball Mills - Mine Engineer.Com

The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed. Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being ...

Do I Need Bigger and Larger SAG Mill Balls

06.09.2013  Ball load is also a factor, as you can operate with a higher ball load of smaller media without risking high ball wear and/or liner damage. So going to a larger 5” ball is a good idea for primary crushed feed with a relatively large grate opening if there’s evidence the 4” ball is not enough to break the coarse particles. Another option is a blend of 4” and 5” media — if this is possible.
