SAG mill is an investment that can produce handsome returns if extra production is needed or simply to give the mine the option to mill the hardest ores at design throughput rates. Typical tests required to define a hardness variability function, are given below in Figure 1.

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.

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. SAG circuits are common in the industry based on: High single-line capacities (leading to capital efficiency) The ability to mill a broad range of ore types in various circuit configurations, with reduced numbers of unit operations (and a ...

The smaller SAG mill media size was recommended due to the wide range of conditions the mill was experiencing: periods of coarse, competent feed followed by high tonnage campaigns of soft, oxide feed with little or no rock load in the mill.

An additional increase of throughput was achieved with these changes. another option was added to the circuit so part of the fresh ore feed to the mill could pass to "Option 5" to work in parallel with the SAG in the cases of having intrusive material and low tonnages.
