By adopting secondary crushing that will reduce the size further to about 40mm or 70mm Grinding on the other hand involves reducing the size such that 80 of the material will pass
Ball Mills For Crushing Gold Ore From a number of case studies it appears that at the fine end of crushing operations equivalent reduction can be achieved for roughly half the energy and costs required by grinding mills flavel ng mills for size reduction with either steel rods rod mills or balls ball mills or sized ore
Grinding takes place through the impact of the powder particles on the rotating and fixed grinding surfaces Typically used for softer materials of up to 3 Mohs hardness an impact mill provides an operationally costeffective solution when hardness and particle size parameters fall within its range
