Within the scope, series of batch grinding tests were undertaken with laboratory scale vertically/horizontally orientable stirred mill and four different stirrer designs (3-pin, 5-pin, 3-disc, and 5-disc) having the same diameter. Experimental results were evaluated based on the stress energy analysis. It is shown that comminution behaviors of different stirrer designs and mill orientations can be explained by the stress energy model. Over energy input 750 kJ/kg d50 of the product is reduced by replacing stirrer designs. Copyright © IMCET 2019 International Mining Congress and Exhibition of Turkey.
