Experimental study of residence time distributions of ball

Experimental Study Of Residence Time Distributions Of Ball

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 LD ratios, the mean residence times of solid were also determined from measured mill holdups. Holdup increased with increased mill feed rate, but the ...
