Mill drive selection for semiautogenous grinding mills
Early SAG mill designs using gear drives were limited in the amount of power that could be applied to the pin-ions, 3.7 MPa (5000 hp). The exception to this design was the Hibbing taconite operation. It used two4.47 MPa (6000 hp) motors to drive a 1I-m-diam x 4.5-m long (36-ft-diam x 15 ft) autogenous mill. However, recent SAG mill designs now ...

A Look Inside the 3rd PTFI SAG Mill That Adds More Power …
Adding another SAG mill to the two existing ones at the mill. A SAG or semi-autogenous mill uses steel ball and the ore itself to break up the rock into fine particles in order to separate the copper and gold from all the non-valuable constituents of the ore, or gangue. Before 2019, the mill could operate at 250 ktpd.
Understanding the SAG Mill in Copper Ore Mining Process
A SAG mill, or semi-autogenous grinding mill, is a type of machine used in mining and mineral processing operations. It uses the crushing and grinding action of rocks to reduce materials such as copper ore into smaller pieces for further processing. Unlike traditional …

Choosing a SAG Mill to Achieve Design Performance
performing SAG mill. It is possible in some cases to modify a SAG circuit to force it to perform better, but this often takes time, much effort and costly modifications. In most cases the capital spent on a properly sized SAG mill may prevent production losses that would be many times greater over the extended start up period.
