2020-10-9 · (SAG) mill and an autogenous mill are used in the grinding process. A SAG mill grinds through the impact of rock and grinding media, while an autogenous mill grinds only through the impact of rock. An autogenous mill is more suitable for smaller particle size requirements, while a SAG mill is more suitable for the roughing process and is a relatively mature process. A SAG mill has advantages,

SAG mill ball charge determination and its influence

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 parameters such as total volume, power draw and total mill
