Bond Work Index - an overview | ScienceDirect Topics
The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 3.10), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material ...
A procedure for rapid determination of the Bond work index ...
Starting from the first-order grinding kinetics defined by means of the Bond ball mill, this stone discusses a simplified procedure for a rapid determination of the work index by just two grinding tests. The applicability of the simplified procedure has been proved on …

THE BOND WORK INDEX OF LIMESTONE AND ANDESITE …
limestone : andesite = 75 : 25. The Bond work index determination according to the standard Bonds test is done on all these samples with compara-tive sieve size of 74, 105 and 150 microns. The Bond Work Index is calculated using the formula (Bond, 1961): (√ √) (1) where: W i – Bond work index (kWh/t); P c – test sieve mesh size (µm);

The Bond work index, Wi, is defined in a Bond ball mill on the samples of standard size − 3.327 + 0 mm.
QUICK METHOD FOR BOND WORK INDEXAPPROXIMATE …
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.
