This is a typical pattern for a well set up closed milling circuit for an easy-to-grind material. Note the nice balance between the size reduction in the mill and the size reduction that is achieved by the circulating load. Note however the crossing of the feed size distributions at about 4mm which is a symptom of too small a ball.
