AG Autogenous Grinding

06/08/2015· With proper rate ratio and size ratio of media to feed, the intermediate rock mill was as efficient as the rod mill—ball mill circuit. Liner wear in the test mill was higher than in the rod mill—ball mill circuit but total steel consumed was considerably less. Estimated saving for inter-mediate autogenous grinding is 65 to 70% of the cost

Mill (grinding) Wikipedia

Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency. Autogenous mill. Autogenous or autogenic mills

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 mill. Via the use of sophisticated instruments
