limestone : andesite = 75 : 25. The Bond work index determination according to the standard Bond's 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's standard ball mill is used to determine the work index value of differ ent samples. The Bond work index is defined as the kilowatt-hours per short ton required to break from infinite size to a product size of 80% passing 100 µm. If the breakage characteristics of a material remain constant over all size ranges, the calcul ated work
Limestone is a type of carbonate sedimentary rock.It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.In old USGS publications, dolomite was referred to as magnesian limestone, a term now reserved for magnesium ...

The Bond Work Index approach is the standard method of selecting ball mills to grind from about 3 mm to 25 µm provided that correction factors are used if necessary. The power prediction is fairly accurate for devices that produce a product with a size distribution parallel to that of the feed.
18-01-2021 The Bond work index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test. Its value constitutes ore characteristic and is used for industrial comminution plants designing. Determining the Bond work index value is quite complicated, timeconsuming and requires trained operating personnel and therefore is subjected to errors.

* Bond F. C., “Crushing Tests by Pressure and Impact”, Trans AIME, Vol 169, 1947, pp 58-66. Bond Rod Mill Grindability Test. The test determines the Bond Rod Mill Work Index which is used with Bond’s Third Theory of Comminution to calculate net power requirements when sizing ball mills*. Various correction factors may have to be applied.
