QUICK METHOD FOR BOND WORK INDEXAPPROXIMATE VALUE
The aim of this study was to develop a new method for assessing the Bond work index in a ball mill (BBWI), which is based on a first order kinetics present in the Bond ball mill for grinding mineral raw materials (Austin et al, 1981; Ahmadi and Shahsavari, 2009).

The operating principle of the ball mill
Therefore, the work of the mill with partial load conditions is unprofitable Energy consumption for ball mills is a function of many factors: the physical properties of the ground material — its specific gravity and hardness; the degree of drum filling by grinding balls; the number of drum rotations, etc Ball mills have low efficiency — no more than 15%.

Ball Mill
DEFINITON: • A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering etc 6 PRINCIPLE: A ball mill works on the principle of impact and attrition size reduction is done by impact as the balls drop from near the top of the shell.

Bond Work Index
Ball mill design requires a Bond work index, BWi, for ball mills at the correct passing size; SAG mill design requires an appropriate SAG test, for example, SPI (Chapter 5) Flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral ( Chapter 12 ).
