SAG and AG Mill – Amstar Corporation
Since the early 1990s, we have been designing and manufacturing Semi Autogenous (SAG) and Autogenous (AG) Grinding Mills. 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 ...

Mill (grinding) - Wikipedia
SAG mill. SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.
Autogenous and Semi-Autogenous Mills - ScienceDirect
Mills that grind hard ores with fracture characteristics that do not lend themselves to fully autogenous milling are charged with a small amount of steel balls to assist in the size reduction. These are known as semi-autogenous grinding (SAG) mills. In the mining industry all of these types of mills are in use.
AN OVERVIEW OF SINGLE STAGE AUTOGENOUS AND …
Over the years the design and operation of single stage autogenous and semi autogenous grinding mills has been a rather hit and miss affair, with some great successes and some dismal failures, with the majority of installation somewhere between. Yet the simplicity, low capital and seemingly simple operation make this a circuit of choice for many.
Autogenous Grinding & Semi Autogenous Grinding Circuits
Autogenous grinding is favored when the ore is quite competent and a fine grind is required. Semi-autogenous grinding is applied when fine crushing could cause severe problems or when ore is variable in hardness or competency. Figure 2 shows a typical conventional crushing-grinding circuit with three stages of crushing followed by ball mills or ...
