Toward sustainability by bridging the gap in comminution - from finely crushed ore to stirred media milling


Mining consumes approximately 7% of the world’s energy from which almost half goes for comminution. Since the crushers are more energy efficient than mills, it is logic to push down-sizing in crushing stage(s) as far as possible. That has been Sandvik’s strategy in supplying crushers, including Vibrocone™ by which an exceptionally fine crushed product can be obtained.

The implementation of stirred media milling to grind the finely crushed gold ore by the Vibrocone™ is presented and discussed herein. Experimental results showed there are potentials in saving energy and costs in comminution by bridging the gap between crushing and grinding in comminution practices.
