2014-6-14The mill was running at a speed of 75 of critical 58.8 rpm with a ball load of 20 of mill volume. The load toe position corresponds to the point where the signal begins to drop continuously to the lowest level as the sensor goes underneath the load while the shoulder position is estimated as the point where the signal begins to rise steadily as the sensor emerges out of the load
