How we measure efficiency in crushing and grinding in a mine

This isn& 39;t particularly useful as there are 4 laws Kick, Rittinger, Bond, Hukki of comminution all of which can be shown to be theoretically correct. Closed circuit unit operations are invariably used as they are 20 - 30% typical

The determination of the efficiency of the milling process - SAIMM

There are indi ions that slow crushing under stiff conditions is the most efficient method of breakage that can be devised. The com- parison with ball milling results thus yields a value for the efficiency of ball milling of approximate
