Mill Use And Process Ore Crushed

ASARCO » Milling

SAG mills use larger pieces of ore to break up the smaller pieces (autogenous — does it by itself). The larger pieces break down as well. The larger pieces break down as well. To help the process along, eight-inch-diameter steel balls are added to the rocks as they tumble inside the rotating mill (semi-autogenous — gets some help from the ...

Crushing and milling Mining of mineral resources Siyavula

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?
