The Bond work index (BWI), expressed in kilowatt hours by ton, characterizes the potential for a material to be reduced from a theoretically infinite size to a powder with 80% particle size less than 100 μm. The BWI value is 13 kWh/t and 14 kWh/t for dolostone and limestone, respectively (Lowrison 1974).

micrometers in size. According to the Bond standard procedure, the work index is determined by simulating a dry grinding in a closed circuit in the Bond ball mill to achieve 250% circulating load (Bond, 1949, 1952, 1961). The test is performed on a raw material approximately weighing 10 kg, which coarseness is 100% -3.327 mm.
