Mill Speed as a Manipulated Variable for Ball Mill ...

1983-1-1  Sydvaranger processes iron ore through a 21 by 33-foot variable speed ball mill. The speed range of this mill is from 62 to 82 percent of critical, with normal operating speed at 78 percent. The manufacturer of this mill, Siemens AG, suggests that the optimization of grinding using variable mill speed could result in a 10 to 15 percent savings in energy (Meintrup, Kleiner, 1982).
