We have studied the oxidation behavior of ballmilled precursors by thermogravimetry. Figure 1 shows the TG profile of the ballmilled precursors versus temperature. The initial Fig. 2 Xray diffraction patterns of samples S1, S2 and S3 weight loss observed in the 30170°C temperature range is related to the removal of absorbed water.

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.
