Selection of AC induction motors for cement plant ...
Motor torque output varies as the square of the voltage change. Therefore, with an auto transformer starter with a 65% tap setting, the 65% voltage results in only 42,2% of the nameplate starting torques (assuming no line drop). The use of adjustable speed drives (ASDs) is becoming a more frequent.

Motors for Metal Rolling Mills | TMEIC
AC adjustable speed motor drive systems are the preferred technology for new rolling mill installations and modernization projects. TMEIC designs and manufactures two types of AC solutions for this purpose. Salient pole synchronous motors that meet the high power and torque demands of a hot strip mill, as well as roughing and finishing stands.

Cement mill Wikipedia
The smaller grades are occasionally cylindrical ("pebs") rather than spherical. There exists a speed of rotation (the "critical speed") at which the contents of the mill would simply ride over the roof of the mill due to centrifugal action. The critical speed (rpm) is given by: n C = / √ d, where d is the internal diameter in metres. Ball mills are normally operated at around 75% of critical speed, so a mill with .
