For ball mills, which are usually used at particle sizes intermediate of those found in fine grinding processes and crushing processes, Bond's Law is usually used [63]: (9) E = 10 W i 1 x p − 1 x f where W i is the Bond Work Index. The particle sizes in Bond's Law are almost always defined as 80% passing F 80 (feed) and P 80 (product) …
