29/10/2007 RESIDENCE TIME DISTRIBUTIONS IN BALL MILLS. A review is made of the methods and theory of measurements of residence time distributions (RTD's) in mills. Literature data on RTD's is assembled. The mean residence times indicate that some industrial mills are operated in the over–filled condition, leading to poor breakage conditions.

residence time distributions in ball mills

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. Holdup increased with increased mill feed rate, but the

Residence time distributions in mills Semantic Scholar

Analysis of experimental residence time distributions from two large mills, (one with a circulation ratio of 9.4 the other with a circulation ratio of 1.5) indicates that the results agree with the one dimensional diffusion/mixing model, with a controlling parameter D/uL equal to about 0.07. In the first case the velocity of flow was about 6.5 ft/min and D was 16 ft/min; in the second, 5.7 ft
