If the maximum locked rotor time is in the order of 5 10 seconds, I would not even try to start the ball mill without the fluid coupling to absorb the slip losses. Next, determine the start current and start torque torque curves. If the curves are not available, just use the LRC and LRT to give an indication.

Starting torque is the minimum force required to initiate the rotation of a bearing from a standstill; running torque is what's needed to maintain rotation. These forces significantly affect the performance of highly sensitive precision components such as gyro gimbals, low power consumption motors, and precision positioning devices.
