Aug 01, 2008  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 ...

Jan 01, 2019  1. Introduction. The material content of a ball mill can be defined either as powder filling or as material hold-up. Powder filling is the fraction of the total volume of interstices between balls at rest inside a mill filled with powder (Austin et al., 1984).Material hold-up, on the other hand, is the mass content of powder or slurry inside a mill depending on whether milling is done dry or wet.
