    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

    Mar 02, 2014 The residence time distribution (RTD) of mineral slurry and slurry holdup volume in an industrial ball mill has been successfully studies using tracer tests. Six different conditions of solids concentration and three levels of ball loading were assessed. The effects of the slurry solids concentration and the ball loading on the mean residence time of slurry were clearly depicted in the
