The Bond Work Index is material specific and is obtained from laboratory crushing tests on the feed material. Hard and brittle materials have a work index in the range 4 × 10 4 − 8 × 10 4 J/kg. Bond's law holds reasonably well for a variety of materials undergoing coarse, medium and fine size reduction. (Eq. ) can also be reduced to
A Bond Ball Mill Work Index test is a standard test for determining the ball mill work index of a sample of ore. It was developed by Fred Bond in 1952 and modified in 1961 JKMRC CO., 2006 . This index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating the energy required.

Commentary on the apparatus of the Bond rod mill Work Index by Alex Doll December, 2015 [email protected] The Bond "Third Theory" of comminution was originally divided into three size classes reflecting the varieties of comminution equipment common during the time period when Bond (and his collaborators) were gathering the .
rod mill work index has not been de ned as yet. The ball fi mill work index is con rmed at 16 kWh/t. The operating fi work index, though, is in the range of 21 kWh/t to 25 kWh/t showing high ineffi ciency. This raises the point that, in some cases, the Bond EF4 .
Bond work index value of these components mixtures is greater than the Bond work index of harder components, clinker. Oner (2000) have conducted a research of clinker and blast furnace slag mixture Bond Work Index in different mass proportions. He found out that these values are always lower than the Bond Index obtained
