Sizing a Regrind Mill for Fine Grinding - Grinding & Classification .Apr 4, 2017 . Whether it is practical and/or worthwhile to run a Bond Ball Mill Work Index test at 500 mesh (25 micron)? Are there calculation alternatives? This would be for sizing of fine grinding or regrind mills.archives regrind ball mill sizing calculations,Can I use BWi Bond Work Index to Size a Regrind Mill: Fine .Feb 1, 2017 . Many power-based grinding models exist, and most operators are familiar with Fred Bond's “third theory”. Bond's model is most commonly used to describe primary and secondary grinding to product sizes above, for example, 100 µm. Operators sometimes use Bond's equation to describe grinding in.
