19-06-2022· The critical speed of a rotating mill is the RPM at which a grinding medium will begin to "centrifuge", namely will start rotating with the mill and therefore cease to carry out useful work. Ball mills have been successfully run at speeds between 60 and 90 percent of critical speed, but most mills operate at speeds between 65 and 79 percent of critical speed.

It is a generator as long as the direction of rotation and torque are the same, and it is a motor if the directions are opposite. In this case, we are still talking about the wind imparting energy to the turbine but in the opposite direction (rotation) than usual. This could work except for one problem, which has to do with the 3-phase power.
