The results indicated that grinding by means of a stirred mill was much more efficient than grinding with a ball mill in terms of size distribution of the products. The energy consumption of the product with d 80 = 78 μm was obtained as 10.53 kWh/t after 1 min of grinding time in the laboratory scale stirred mill.
