    "description": "Most of the costs in open pit quarry operations occur in crushing and grinding processes. Therefore, the management of crushing-grinding processes is very important. Many researchers investigated the effects of pile size distribution and specific charge values occurring as a result of blasting on crusher energy consumptions and provided some cost reductions in the crushers by using suitable explosive. However, these researchers did not sufficiently use discontinuity characteristics of the blasting surface and resistance values of the rock while making these studies. In this study, 15 blasting tests were also realized at two different limestone quarries. Correlations estimating the energy values consumed by primary and secondary crushers were developed by using discontinuity characteristics of blasting surfaces in blast tests, specific charge, and uniaxial compressive strength values of the rock, and compared with energy consumption values measured real timely in the crushers. Very limited error margins were observed in these comparisons. Material exit size at primary crusher must be 15 cm and material exit size at secondary crusher must be 7.5 cm. In addition, primary crusher was of jaw type and secondary crusher was of hammer type.",
