| Popis: | This work presents the results of the Bond work index in a ball mill on samples of carbonate mineral raw material (limestone) of the site Spasina - Brdjani. Value of the Bond Work Index was carried out in a ball mill on six samples of limestone from exploration drill holes. The obtained results indicate that in 4 samples of limestone the value of the Bond Work Index is in the range of 5.9 to 6.4 kWh/t. Higher values of the Bond Work Index are achieved in 2 samples and the same amounts 7.059 and 9.526 kWh/1. The increased value of the Bond Work Index in these samples of limestone is explained by the presence of white-yellow limestone cores and increased magnesium content. |
