Read MoreThis is the instantaneous residence volume for pulp. Next compute the volumetric flow of slurry into your mill, as m³/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.

Residence time is the time it takes a particle to complete the cycle. Space time is volume of the reactor over the velocity. If the volume does not change and the velocity remains constant then

Figure 8.15 Residence-time distribution function for solids in a continuously operating ball mill.into the mill and examining how the specific power input varies with mill size and with design and operating1.35 (8.114) To size a ball mill or rod mill that must process W tons/hr it is necessary to calculate.

This is due to the lower residence time per pass. In a properly designed circuit, each finely ground particle of the required product size has ample opportunity to exit the grinding circuit after each pass through the mill. As a result, few -10 micron fines are generated in the grinding circuit.
