## Calculating Load On A Ball Mill

#### Ball Mills

The ball mill is a cylindrical drum (or cylindrical conical) turning around its horizontal axis. It is partially filled with grinding bodies: cast iron or steel balls, or even flint (silica) or porcelain bearings. Spaces between balls or bearings are occupied by the load to be milled. Following drum rotation, balls or bearings rise by rolling along the cylindrical wall and descending again in ...

01/11/2006 · Load behaviour as an additional mill control parameter is an important aspect because of the relation between the variation of mill power with operating parameters (Austin et al., 1984) and its impacts on mill control. This necessitates the need to study various parameters that affect the load behaviour due to the benefits that would come about not only for control purposes but also for ...

Get Price#### Mill Steel Charge Volume Calculation

19/06/2015 · 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 ...
