The results obtained with the semiindustrial ball mill (see Fig. 4, Fig. 5) were analysed regarding the number of stress events (calculated according to Eq. (6)). For an unchanged ball grading and the same true density of the feed material the number of stress events can be substituted by the average retention time of the feed inside the mill.

To calculate hydraulic retention time (HRT), use the formula: HRT = Volume / Q, where: HRT Hydraulic retention time [h]; Volume Volume of the tank or reactor [m³]; and. Q Influent volumetric flow rate [m³/h]. Let's say, for example, that you'd like to find the HRT of an aeration tank with a capacity of 3000 m3, and the plant's ...
The flowrate Q could be measured from the production P [tons/h] and the circulating load C and given by Q [tons/h] = C P [tons/h] . The circulating load could be obtained by measuring the particle size distribution of the feed, the product and the reject, and by then using the Koulen method. (see this post)
torque mill test is the mill energy input divided by the solids load. The energy specific cumulative grinding rate at each screen size is calculated from a torquemill test as in the example that follows. Torque mill solids load during test: kg ( lb) of ball mill feed sample from plant survey. Sample is reconstituted with water to be
You now have the unit capacity. Then take the volumetric feed rate of the new ore per time. Divide the unit capacity by the feed rate and you have the nominal retention time. Say your unit capacity is 1/2 cubic meter and you are feeding 6 cubic meters per hour, your retention time would be about 5 minutes.

If a ball mill contained only coarse particles, then 100% of the mill grinding volume and power draw would be applied to the grinding of coarse particles. In reality, the mill always contains fines: these fines are present in the ball mill feed and are produced as the particles pass through the mill.
