A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage [1]) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

Crushed ore is reclaimed from the fine ore bin and is fed into the 10′6″ diameter x 13′0″ long single stage overflow ball mill. Leaching is designed to begin in the grinding circuit by the addition of recycled barren solution for repulping. The grinding circuit is a very efficient leaching unit with violent agitation and good aeration.

In the highenergy ball milling process, coarsegrained structures undergo disassociation as the result of severe cyclic deformation induced by milling with stiff balls in a highenergy shaker mill [ 8, 9 ]. This process has been successfully used to produce metals with minimum particle sizes from 4 to 26 nm.
