A total of 15 surveys were performed around the Waterval UG2 Concentrator secondary ball mill at three different ball filling degrees and four in-mill density levels as part of optimisation studies. The filling degree and pulp level were measured using an on-line sensor called Sensomag developed by Magotteaux
