How To Calculate Ball Mill Residence Time

Jan 01, 2011 Residence time distributions normalized by mean residence time as a function of feed rate for centrifugal mill operated at GD 0.4, 60 ball filling, and mill revolution speed of 240 rpm. However, it was found that the shape of the RTD was changed somewhat with an increase in the mill revolution speed, as shown in Fig. 7 .
