For example grinding a pyrite concentrate so that 80 of the particles are less than 12 181m 0012 mm consumes over 120 kilowatthours per tonne kWht of ore in a ball mill using 9 mm balls but only 40 kWht in an IsaMill using a 2 mm grinding medium.
One of the interesting features of HPGR is its capability to produce a particle size distribution with a greater than typical amount of fines thus reducing the power requirement for the downstream ball mill This makes the use of standard ball mill analyses based on the K80 inadequate unless appropriate corrections are made This problem is.
