Get PriceCommentary on the apparatus of theBond rod mill WorkIndex by Alex Doll December, 2015 [email protected] TheBond“Third Theory” of comminution was originally divided into three size classes reflecting the varieties of comminution equipment common during the time period whenBond(and his collaborators) were gathering the information to calibrate comminution models. The middle …
Therod mill workindex laboratory test is conducted by grinding an ore sample prepared to 80% passing 12.7 mm (½ inch, the original test being developed in imperial units) to a product size of approximately 1 mm (in the original and still the standard, 14 mesh; see Chapter 4 for definition of mesh), thus determining therod mill workindex ...
