In comminution circuits, the Rosin-Rammler (RR) distribution is an industry-standard model for describing milled particle size. This two-parameter model, using characteristic size D' and uniformity index n, enables plant engineers to detect ultrafines excursions early. This diagnostic is crucial for supervisory control loops in various milling operations to prevent downstream bottlenecks.
