    Residence time distributions (RTDs) were estimated by water tracing in a number of wet overflow ball mills (diameters 0.38 to 4.65 m) producing dense coal-water slurries. In open-circuit mills of 0.38 m diameter and various length-diameter (L/D) ratios the mean residence times of solid were also determined from measured mill holdups.
