More## The energy efficiency of ball milling in comminution ...

01/11/2002 Schellinger's calculated ball mill efficiency, in dry or wet ball mill grinding, ranges between 10% and 19%, with the higher figure occurring at the optimal mill loading. In terms of the Brace and Walsh surface free energy of quartz, his results give a ball mill efficiency that is less than 0.5%.

More## The energy efficiency of ball milling in comminution ...

If the energy to produce new surface by single-particle breakage is used as the basis for evaluating efficiency, then the efficiency of ball milling has a more realistic value of about 15% for the comminution of quartz and soda-lime Limestone.

More## Mill Steel Charge Volume Calculation

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. The % loading or change volume can then be read off the graph below or ...
