Making "digital twins" for rolling processes and mill equipment should begin with the development of mathematical models of the deformation zone. The deformation zone of two-high flat mill rolling have been studied in detail, relevant models are available in many academic papers. However, the same cannot be said about the most complex deformation zones in stands with multi-roll …

The motor power draw required to turn a mill from rest to the operating speed includes the energy required for the initial starting torque and mechanical arrangements to rotate the mill. It is generally accepted that practical mill power (PM ) is a function of mill capacity and diameter, i.e.,P M = Mill Constant * (Mill Diameter ) n

Cleary et al. (2003) then provided an innovative approach to investigating ball mills by evaluating the accuracy of the results obtained from 2D and 3D DEM simulations on the basis of a comparison of the simulation and experimental results; the researchers also quantitatively studied how particle shape affects the power draw of ball mills.

Motor torque, load torque and selection of motors 2/45 Performance In such motors the pull-out torque is normally less than the starting torque. This is because the pull-out torques by the two cages occur at different speeds. Such motors would possess a low power factor and efficiency compared to an ordinary squirrel cage motor, because of the high

3. High Power and Torque Possible: The spindle motor is mounted externally from the actual spindle shaft. Therefore, it is often possible to use a very large motor. A large motor, particularly one of large diameter, can provide very high torque and high power for spindle use. This is much more difficult in an integral motor-spindle design, as
