The grinding curve is the product size as a function of feedrate, for a fixed feed size. It is proposed that for each new milling condition, in this case a change in the percentage of ball scats in a mill, the peak in the grinding curve must be sought, and that must be used as the comparative test condition.

2011-9-23 Like the AG Power Model the charge volume estimator is based upon the Morrell C Model. The model is used to determine the power curve for a particular set of conditions. The curve is then interpreted to give the charge volume in terms of a mill fractional filling. The model also outputs the charge toe and shoulder angles.

2015-4-16 Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between

2009-8-26 The absorbed power is calculated by multiplying the torque on the driving shaft with the shaft speed (rad/sec) and hence excludes any losses associated with the gearbox and motor. The pulp weight in the mill is obtained by subtracting the mill weight during the test from the empty mill weight, including the ball charge, at the start of the test ...
