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. In fact grinding is the most consume energy section for the whole processing plant, up to ...
