25.3 Crushing and milling | Mining of mineral resources ...

Inside a ball mill, the balls move round in a circle as the mill turns, crushing the ore into a powder. This process of reducing the size of the rocks requires a lot of energy. Just image how hard it is to break a rock. How much more energy do you think is needed to crush a rock until it is like sand? This is one of the steps in the mining process that is very expensive because

Crushing in Mineral Processing

26.12.2015 · After the mine has blasted the ore, the first reason why we crush rock is really to be able to transport it onto the next same. Conveyors and transfer chutes are limited in size and I say AMEN! to that as if you are left to the mining engineers, they’d blast and send 60″ rock to the SAG mill 😉 . Since each size reduction stages of crushing is limited to around 6-to-1 (average),
