2016-11-18 Some experimentation is inevitable in determining the exact amounts of material charge to use. While the media charge should always be 50%, material charge will vary from 25% to 40% or more in some cases such as when grinding 100% homemade airfloat charcoal. The best way to tell if your mill is properly charge is to listen to it after
