  (Power = Torque × Speed × 2 π), the power varies in the constant torque speed range and the torque varies in the speed range with constant power. The operator must keep the process demand for power and torque below these constraints (eg. by adjusting mill speed or charge level) while still operating in an efficient manner. The owner''s choice of the knee point (motor rated speed) coupled ...

  01/03/2020· Since the drill''s power output is constant and the rotational speed and torque of its motor are inversely proportional, the variable for torque can be ignored in Eq. . However, in a drill powered by an internal combustion engine (the standard in mines), feed force, rotational speed, and torque respond independently, and torque (τ) varies depending on the revolutions per minute (RPM) and ...
