A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.
Autogenous and Semi-Autogenous Mills The optimum solution for wet grinding. 2 AG/AG Mills AG/AG Mills 3 's AG/SAG mills accomplish the same size reduction work as 2 or 3 stages of crushing and screening The feed size for these mills is limited to the maximum size that can be practically conveyed and introduced into the large mill feed chutes. And the product of the large AG/SAG …
SAG AG Mills Since the early 1980s FL has been designing and manufacturing both semi-autogenous (SAG) and autogenous (AG) grinding mills under the Fuller-Traylor brand. Fuller-Traylor SAG/AG mills range in size from 18' through 40' in diameter with powers as high as 30,000 hp.
SAG Mill Reline times are a function of the number of pieces to be changed and the time required per piece. Advances in casting and development of progressively larger lining machines have allowed larger and larger individual liner pieces.
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.

5 The SAG mill model in the JKSimMet software has not been shown to accurately reproduce the performance of a single stage mill for greenfield design.
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).
SAG Mill Grinding Circuit Design. AG and SAG mills are now the primary unit operation for the majority of large grinding circuits, and form the basis for a variety of circuit configurations.
grinding mills. Grinding mills supplied by FL have their origins dating back to the Fuller Company, based in Bethlehem, Pennsylvania, USA. Fuller has been a leading supplier of grinding mills under the Traylor brand name since 1902 and many of the largest plants operating today have these world renowned SAG and Ball Mills operating in some of the most extreme environments.

There are several SAG mill specific design tests available to determine the amenability of an ore to SAG milling and the resultant SAG mill specific energy. Recent projects that have failed to achieve design throughput have typically failed to take sufficient heed of the indications of ore competency in the test work data or analysis of the data.
