Autogenous and Semi-Autogenous Mills FL

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

An EKF observer to estimate semi-autogenous grinding mill

A non-linear observer model of a semi-autogenous grinding mill is developed. The observer model distinguishes between the volumetric hold-up of water solids and the grinding media in the mill. Solids refer to all ore small enough to discharge through the end-discharge grate and grinding media refers to the rocks and steel balls.
