In this study, the use of olive pomace oil as a grinding aid was investigated in the grinding of calcite to dry micronized sizes in a laboratory scale stirred ball mill. For this purpose, in the first stage, different stress intensities were created and optimum grinding conditions were determined. In the second stage, the usability of olive pomace oil was investigated and compared with triethanolamine, a pure grinding aid. The experimental results were evaluated considering the amount of grinding aid, energy consumption, and particle size. According to the results obtained, the optimum stress intensity range was determined as approximately 1-2*10-3 Nm at 500 kJ/kg and 1000 kJ/kg energy levels. With the use of grinding aid (TEA and olive pomace oil), products with a particle size of 4 μm and finer sizes were produced at 2000 kJ/kg energy level. At advanced energy consumptions (1000 kJ/kg and 2000 kJ/kg), it was obtained similar particle sizes by the use of olive pomace oil compared to the TEA. |
