Pharmaceutical uses of Ball Mill. 1. The small and average capacity ball mills are used for the final grinding of drugs or for grinding suspensions. 2. The maximum capacity ball mills are used for milling ores prior to manufacture of pharmaceutical chemicals.
Example Ball Mill GrindingExpert Solution The throughput and efciency of a SAG mill depends on the volumetric load: An overloaded mill has reduced coarse ore breakage, as the cascading balls and rock cannot drop far enough, reducing kinetic energy for breakage. An underloaded mill will break coarse ore well, but at the expense of added
