    The average residence time of the ore in the mill is 30–60 seconds. There is negligible shortcircuiting of the grinding zone by the feed, as a result of having multiple grinding chambers in series. The ground product is separated from the grinding medium at the discharge end of the mill.

    A combination of more sharply angled upper cones, followed by longer, angled lower cones maximises tangential velocity in the upper part of the cyclone while it provides a long residence time in the lower section. The result is a substantially finer separation, with fewer fines in the underflow and less coarse material bypass to overflow.
