With external circuit the air velocity can be greatly reduced from 45-65 m/s. to 30-45 m/s to allow material larger than 10 mm to fall through the ring and fed back to the mill at the top along with fresh feed. This reduces pressure drop to about 400 mmwc reducing fan power by a corresponding amount.
