"Effect of Milling Environment on the Breakage Rates in ...

+

In ball milling the rates of breakage vary primarily with the size distribution of powder in the mill. Using an approximate solution to the batchgrinding equation, the acceleration and deceleration of breakage rates of all individual size classes are determined when the grinding environment is varied. Experimental results with limestone and copper ore show timedependent breakage rates under ...
