SAG mill fractional total filling (Jt) and ball filling (Jb) are determined by solving the powerdraw or mill weight equations given mill power draw or weight process measurements as inputs. 4.
Get Quote2009-10-1 · SAG mill fractional total filling (J t) and ball filling (J b) are determined by solving the powerdraw or mill weight residuals given mill power draw or weight process measurements as inputs. SAG mill fractional rock charge filling (J r) is calculated by difference of the total and ball charge fractions, see Eq. . (11) J r = J t-J b
Get QuoteSemi-autogenous (SAG) mill total load and ball load have a marked influence on mill performance. Direct measurement of these inventories is difficult, hence inferential measurement is an attractive option to open the way to their control.
Get Quote2020-10-9 · (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,
