The Bond ball mill work index is one of the most commonly used grindability tests in mining, and is often referred to as the Bond work index.. The test is a 'lockedcycle' test where ground product is removed from test cycles and replaced by fresh feed.
Size analysis of the ball mill for the same duration feed and discharged for the two minerals were carried out. The work index was found to be approximately KWh/ton. Ajayi (1998) determined the work index of Julius Berger Granite in Kogi State of Nigeria using the modified Bond's method.
The Bond work index, W i, is defined in a Bond ball mill on the samples of standard size −.+ practice, it is possible to find materials of nonstandard size that are finer In this work, a procedure for the calculation of the Bond work index is suggested for cases when the Bond grindability test is conducted on samples of non ...
In this thesis the common Bond ball mill grindability test is conducted on three different sample materials. The samples show good variability in terms of mineralogy and grindability. Along with the Bond test, the Mergan ball mill grindability test is also conducted on the same sample materials. The Mergan test is faster than the Bond test,
#; The Bond Ball Mill Work Index is a measure of the resistance of the material to grinding in a ball mill. It can be used to determine the grinding power required for a given throughput of material under ball mill grinding conditions.
Bond Rod Mill Grindability Test. The test determines the Bond Rod Mill Work Index which is used with Bond's Third Theory of Comminution to calculate net power requirements when sizing ball mills*. Various correction factors may have to be applied. The test is a closedcircuit dry grindability test performed in a standard rod mill.
