milling in exactly the same way as the Bond laboratory ball mill work index can be used to compare the relative grindability of different ores in ball milling (Bond, 1961 and Rowland and Kjos, 1980) To use the Bond ball mill work index to determine the ball mill specific energy required for a particular
laboratory tests, typically Bond ball mill Work Index and SMC test® / JKDWT A*b (Bond, 1961; Morrell, 2004). Due to budgetary constraints, this has curtailed the collection of sufﬁ cient number of BMWi or A*b measurements to allow the inherent variability to be adequately quantiﬁ ed for direct estimation into a block model for mine planning.
The Bond Ball Mill Work Index (BBWi) test is carried out in a standardised ball mill with a predefined media and ore charge. The Work Index calculated from the testing can be used in the design and analysis of ball mill circuits. The test requires a minimum of 10kg of sample that has been stagecrushed to 100% passing size of < mm.
correlation between the abrasion value(X2) and work index (Wi) is found to be Wi = Ln (X2) + with correlation coefficient of KEYWORDS: Bond work index ± Mechanical properties of rocks ± Grinding energy Crushing resistance 1 INTRODUCTION Comminution in a mineral processing plant, or mill, involves a sequence of crushi ng

The rod mill work index laboratory test is conducted by grinding an ore sample prepared to 80% passing 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 the rod mill work index (Wi R or RWi).

Wi = Work Index (kWh/t) P = 80% passing size for the product (P 80) F = 80% passing size for the feed (F 80) Bond's approach consists of determining the ore hardness characteristics, or Work Index (Wi) via standardized laboratory testwork. The full suite of Bond comminution tests provide the Ball Mill Work
· Sizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper. According to Bond's Third Theory of Comminution, the work/energy input is proportional to the new crack tip length created during particle breakage and equivalent to the work represented by the product – the feed.
Ball mill charge size distributions originally specified for Bond grindability tests to determine the Bond Work index (BWi) are not commercially available. Those proposed to date do not match all of Bond's (1961) original specifiions of total ball mass, number and surface area.
