  • Semi Autogenous Grinding Mill an overview

    Autogenous and Semi-Autogenous Mills. A. Gupta, D.S. Yan, in Mineral Processing Design and Operation, 2006. 9.1. In a SAG mill the dimensions of the mill were 9.75 m × 3.5 m and the specific gravities of the mineral and that of the balls charged were 4.1 and 7.9 respectively. The mill was rotated at 75% of its critical speed when 8 % of the mill volume was charged with grinding balls

  • Autogenous and Semi-Autogenous Mills ScienceDirect

    01.01.2016· These are known as semi-autogenous grinding (SAG) mills. In the mining industry all of these types of mills are in use. In the mining industry all of these types of mills are in use. The disintegration and size reduction of ores in AG/SAG mills is brought about by a combination of impact, attrition and abrasion forces during mill rotation.

  • Autogenous and Semi-Autogenous Mills FLSmidth

    Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in the
