Commentary on the apparatus of theBond rod mill Work Indexby 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…
The Bond rod mill work indexis not as common as the Bond ball mill work index,and there are two different variations on the mill apparatus.The SAGMILLING.COM models expect a mill with a "wave liner", and is not compatible with mills using "smooth liners". Most laboratories outside of Australia use the wave liner style of machine – these results can safely be used in the models.
The Bond Index conforming rod charge consists of:6 rods of 1.25“ diameter and 21“ length; 2 rods of 1.75“ diameter and 21“ length;The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a wave-shaped design. At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill.
Jan 01, 2013· The Bond rod-mill work index is used inconjunction with Bond’s third theory of comminution to merely calculate net energy requirements for sizing rod-mills.This test was originally developed in the mid 1930s by F.C. Bond. Though, it was altered in succeeding years, it has essentially remained unchanged since 1961.
