ABSTRACT
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, in...
