high density mineral separate grinding ball mill

IsaMill

IsaMill Operating Principles. For example, grinding a pyrite concentrate so that 80% of the particles are less than 12 m (0.012 mm) consumes over 120 kilowatt hours per tonne (kWh/t) of ore in a ball mill using 9 mm balls, but only 40 kWh/t in an IsaMill using a 2 mm grinding medium.
