THE BOND WORK INDEX OF LIMESTONE AND ANDESITE

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);
