A clear definition of the required crushing capacities and the desired product quality can be precisely determined by using the Bond Index test methods. Using the Bond Index test procedures it is possible tocalculate crushing / abrasion behavior of mineral samples.This knowledge is essential to define the required ball mill layout and production capacity. In order to perform the Bond Index Test successfully …
The ability to simulate theBondworkindextest also allows examination of truncated ballmillfeed size distributions on the workindex. For grinding circuits where the feed to a ballmillis sent directly to the classifier and the cyclone underflow feeds the ballmill(see Figure 3.10), a question arises as to whether this practice will alter the ballmillworkindex(BW i) of the material ...
TheBond Ball Mill WorkIndex(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 100% passing size of <3.35 mm.
