Ball Size Calculator. Warning Theres currently no reliable or recommended source of information about these averages. A page for measuring the volume of balls I guess. This is not a very organized page, take every result with a grain of salt. All measurements should be of one single testicle, not both of them.
The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent. It is especially difficult to teach mill
