  • Crushing Vs Grinding - Minerallurgy
    Crushing Vs Grinding - Minerallurgy

    Both crushing and grinding require energy to reduce the ore size. However, in grinding operations we consume much more eneregy than crushing, up to 100 times ( thousands of kw compared to tens in crushing). Because as far as we go to finer size we need more force and collosions for further size reduction
