Since the reclaim tunnel conveyor is fed by six belt feeders and the conveyor is driven by two VFDs, the changes in flow rate and belt speed were simple. The feed rate from the six feeders was reduced while the power supply frequency to the two Motorized Pulleys was reduced from 60 Hz to Hz (reducing the reclaim tunnel belt speed from 384 fpm to 244 fpm.)
