    Mono Chamber Raw Mill Ball Charge Design. Hi experts I want to design a ball charge for a mono-chamber raw mill in a white cement plant and wanted to know your opinion about it. The raw material is pre-ground by to a hammer crusher and after separation by a third generation separator the course material is fed to the mono-chamber raw mill.

    1990-5-24 · Abstract In semi-autogenous grinding (SAG) the grinding mill inventory (i.e. volume of total charge volume of ball charge etc.) is important in determining the optimum operating condition for maximum production (tph) minimum specific energy (kwh/t) or lowest cost ( /t). A two-dimensional graphical method is presented for determining the actual ball charge within the total charge when
