Dear Specialists,
I'm designing a ball mill circuit to grind the crushed gold ore from F80 9.5mm to P80 130 microns, simulation showed if we use one ball mill it would be 3m x 4.3m with 800hp motor, and if I use 2 ball mills with same power then each would be 2.5m x 3.9m and 420hp, to split the power equally between 2 ball mills (first mill open circuit and second closed circuit with cyclone), the F80 and P80 of ball mills would be 9.5mm - 450 microns - 130 microns. the plant will be built under ground, therefore, it is preferred to use low profile, compact equipment and less quantities with larger size. please let me know from operation wise which circuit is more practical and has more advantages.
Thanks in advance for your time and attention.
