Firstly, standard bond work index tests were carried out for limestone and clinker samples and, the bond work index values for both the samples are found to be 13.52 kwh/t and 13.69 kwh/t respectively. the standard set of grinding conditions used is shown in table 2. eight mono-size fractions (-1.7+1.18, -1.18+0.850, -0.850+0.600,.
For ore a a bond ball mill work index value of 17 kwh/t was reported. for ore b a bond ball mill work index value of 15 kwh/t was used. further comminution tests will be required in the future to confirm this is representative of the ores to be processed. the bond index values generally indicate that grinding is moderate power.
