An AG mill is a tumbling mill that utilises the ore itself as grinding media. the ore must contain sufficient competent pieces to act as grinding media. An sag mill is an autogenous mill that utilises steel balls in addition to the natural grinding media (wills mineral oct 04, 2019 In the present work, vibration, acoustic and thermal signals were correlated to the semi-autogenous grinding mill working parameters such as total power and inlet water flow rate, and then these parameters were monitored using vibration, acoustic and thermal analyses. next, the influential controlling parameters were obtained to monitor the mill conditions via spss software and afterward nov 26, 2019 agsag is short for autogenous mill and semi-autogenous mill, it combines with two functions of crushing and grinding, uses the ground material itself as the grinding media, through the mutual impact and grinding action to gradually reduce the material size.
semi-autogenous grinding and autogenous grinding mills are used for grinding large chunks of materials into smaller pieces which can be later used for processing. such mills are used in the primary stage of grinding process where pieces of raw materials need to be grounded for further processing or prominer provides ball mill rod mill grinding system which is widely used in various types of ores beneficiation, electricity, cement and chemical industries.nov 26, 2019 AG sag is short for autogenous mill and semi-autogenous mill, it combines with two functions of crushing and grinding, uses the ground material itself as the grinding media sag mill. definition. sag mill means a semi -autogenous grinding mill. sag mill is one in which steel balls are added to the mill charge to supplement the grinding capabilities of the larger pieces of ore. sag mill means a lined steel cylindrical vessel filled with steel balls in which a technological operation of grinding takes place.sag mill liner development draws primarily on practical experience from sag milling operations supported by computer-based modeling of charge motion in sag mills and on established good design practice. liner design needs to respond to the process aspects of mill liner action that are critical to good sag mill performance, i.e the impact of shell liners on the grinding action and of grates
