A 22-liters laboratory grinding ball mill was used; its drum diameter (D) and length (L) were 300 and 300 mm, respectively. The mill operated at 75% of the critical rotational speed (N c = 42.3 / D), which corresponded to 75 rpm. A total of 40 kg stainless steel balls (20 kg of 15-mm diameter and 20 kg of 5-mm diameter) were employed.
