The Bond Ball Mill Work Index (BBWi) test is carried out in a standardised ball mill with a pre-defined media and ore charge. The Work Index calculated from the testing can be used in the design and analysis of ball mill circuits. The test requires a minimum of 10kg of sample that has been stage-crushed to passing size of <3.35 mm.

size reduction circuits (Charles, 1957). However Bond's Third Law can be reasonably applied to the range in which ball/rod mills operate in. In spite of the empirical basis of Bond's theory, it is the most widely used method for the sizing of ball/rod mills and has become more likely a standard. The general form of Bond's equation is as ...


Bond crushing law. A. Calls for relatively less energy for the smaller product particles, than does the Rittinger law B. Is less realistic in estimating the power requirements of commercial crushers.
