Minerals | CerCo Corporation

Large-size media are required to fracture particularly hard particles in the mill charge; smaller media fill the voids and promote finer grinding. For continuous grind applications or batch mill, attending to media volume is advisable - maintaining a 40-45% media charge (of mill volume) and keeping throughput constant will provide best results.
