Increase in mill load as a result of overcharging grinding media has of late seen frequent trips as a result of over loads. Generally the motors driving the ball mills have a rated maximum capacity that they can power. Overcharging mills, especially running ball mills has been seen as a cause of these frequent over load trips.
