Determination of bond work index of lucky cement.Determination of bond work index of lucky cement,in this regard calculation of work index of limestone made by standard bond grindability test ball mill was employed to conduct the grinding test of seven different samples among all seven samples collected from the different faces of quarry bond work index of limestone face4a results less.
Test data from the bond ball mill work index test is used to calculate the fine grinding index m ib.The m ia and m ib indices are used to calculate specific energy for the coarse w a and fine w b components of the total grinding specific energy at the pinion w t according to equation 7.
The bond ball mill grindability test is a locked-cycle laboratory grinding test.It provides the bond ball mill work index which expresses the resistance of a material to ball milling.This index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating the energy required for grinding, and for ball mill scale-up.
In 1991 the canadians developed the sagpower index spi, test using 2 kg of material in a 300 mm diameter mill.This test has been further developed by starkey, hindstrom and orser 2006.This test now includes a bond ball mill work index test.The macpherson test is still being offered by some testing facilities.
