(pdf) modeling the rtd of an industrial overflow ball mill

The RTD in the AG mill was described by the N reactors in series model. Makokha et al. (2011) used NaCl for RTD measurements in a ball mill of 7.3 m × 9.6 m that was operated in open circuit. The

Mar 31, 2018 · Residence time distribution studies on tubling ball mills give RTD’s which can be approximated as if they came from a series of fully-mixed reactors in sequence. A particularly convenient form is the one large/two-small reactor model, which has been used in the analysis of operating mills by back calculation of breakage parameters, for

Weigh the fraction of sample retained on each screen. 5. Take the material retained on BSS 12 screen (pore size 1.4 mm) and feed to the ball mill. 6. Run the ball mill for 15 minutes using the specified number of balls (15-25 balls). 7. Sieve (for about 20 minutes) the product using the screens BSS 100, 150, 200 and pan in the sieve shaker
