of start-ups was 129 and thus 6% of the start-ups could have caused locked charge damage. The SAG mill tumbling angles were mostly between 30 and 40 degrees, yet it is interesting to note that some start-ups also had high tumbling angles. As expected, high tumbling angles are reached more often in the ball mill, as the particle size is smaller.
