The Bond ball mill work index is the most commonly used comminution testwork procedure in the Millpower 2000 database, with more than double the number of results of the second most common (the combined drop-weight test methods). The ball mill work index is defined as "the kW-hr per ton to break from infinite size to 100 µm" (Bond, 1952).Design & Resource CenterGold Bond® Products Detailed Gold Bond product information.

Figure 4 SAG mill shellDETERMINATION OF THE BOND'S WORK INDEX OF BABAN .Bond devised several methods for predicting ball-mill and rod-mill energy requirements and provided an accurate measure of ore grindability (Gupta and Yan, 2006). The standard Bond test requires constant screening out of undersized material in a closed circuit operation. The
GeometallurgyThe Bond ball mill work index test is thought to be additive because of its units of energy; nevertheless, experimental blending results show a non-additive behavior.  The SPI(R) value is known not to be an additive parameter, however errors introduced by block kriging are not thought to be significant .Grinding of ceramic raw materials by a standard Bond millJul 18, 2013· The mill used was a size of 30·5 cm diameter, 30·5 cm length, providing a total mill volume of 22 272 cm 3 with a total mass of 22 648 g steel ball mixtures of 38·10, 31·75, 25·40, 19·05 and 12·70 mm diameters, occupying 22% of mill volume and with a speed of rotation of 70 rpm.ComminutionBond Ball Work Index (BBWi) The sample is staged crushed to 100% passing 3.35 mm.

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.LMBRM Ball and Rod MillThe LMBRM ball mill is suitable for normal and Bond grinding, depending on the (size) drum.
