This is the instantaneous residence volume for pulp. Next compute the volumetric flow of slurry into your mill, as m /h or L/s (match whatever volume units you used in the first step). Now divide the instantaneous volume by the vol flow (cancelling the vol units) and you are left with time units; this is your residence time

ball diameters [4]. The residence time was material dependent and thus depended on the grindability or hardness of the sample ore. The products from the four milling processes were screened using a range of different aperture screens to determine the extent of size reduction (comminution ratio) as well as the size distribution of the

Mar 15, 2015 The effect of ball size on optimum residence time on the extent of mill speed is summarised in Fig. 12. This shows that the residence time is largely dependent on ball diameter, and that the residence time can be optimised by the correct adjustment of ball size.
