The effects on mill performance of a varying ratio of these two components in the mill feed are not well described by the current generation of AG/SAG models (Stange, 1996).
AG/SAG mills can accomplish the same size reduction work as two or stages of crushing and screening, a rod mill, and some or all of the work done by a ball mill. All because of the range of mill sizes available, AG/SAG milling extends itself to many applications.

Jul 22, 2014· SAG is an acronym for Semi-Autogenous Grinding, which means that it utilizes steel balls in addition to large rocks for grinding. It has a large diameter and short length.
A Sag mill is most often used in the mining fields, particularly in the mining of precious metals such as gold, copper, silver, and nickel. The sag mill serves in the line of industrial mining equipment designed to process, crush, separate, or locate precious metals from mined coal.
Today we will learn about difference between sag mill vs ball mill. A mill is a machine by which solid or hard materials are broken into smaller pieces by means of grinding, crushing or cutting. This commutation is an essential part of many processes.
AG and SAG grinding mills are considered a mature technology, "so," they ask "why are we seeing a number of recent projects not achieving nameplate capacity and is SAG technology losing market confidence, particularly in financial circles?"
Since the breakage of ore in AG/SAG mills is mostly due to impact on particles and media from a height, these mills generally have a large diameter-to-length (D/L) ratio. However, this ratio varies and mills with large length-to-diameter ratio are also in use, e.g., in South Africa.
Autogenous mills(AG Mill)/ semiautogenous mills(SAG Mill) The CITIC autogenous / semiautogenous mills are utilized to grind run-of-mine rock or primary crusher discharge. The feed size to this mill is limited to the maximum size that can be practically conveyed and introduced into the mill.

influence of feed size on ag/sag mill performance, recognized an opportunity in the relationship between feed size and mill performance and, with sag mills being increasingly less so as the ball charge is increased, balance between coarse and intermediate size rocks is different to that
After long term of R&D, design and test, Naipu has successfully applied rubber liners, composite liners and rubber trommel screens in ball mills, SAG mills and AG mills, and has achieved significant tech breakthrough and innovation.
With a higher density mill charge. SAG mills have a higher installed power density for a given plant footprint relative to AC mills. With the combination of finer grind and a lower installed power density (based on the lower density of the mill charge), a typical AG mill has a lower throughput, a lower power draw, and produces a finer grind.
