SAG is an acronym for semiautogenous 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'' () in diameter, powered by a 28 MW (38,000 HP) motor.
Some dry autogenous mills operating in Canada are m in diameter and m in length. These are known as Aerofall mills. The Cadia Hill (Australia) wet SAG mill is m in diameter with a 20 MW motor and in 2004 was the largest diameter mill in operation in the world.

Filler is injected into the face alongside little blood vessels—and if injected poorly, it can lead to blindness, skin necrosis, and other serious adverse reactions. An experienced injector will know which type of filler to inject where and, hopefully, will have the vision to create a reasonable expectation and result," says Dr. Shah.
Our GMD eliminates all mechanical components of a conventional mill drive system, such as ringgear, pinion, gearbox, coupling, motor shaft and motor bearings: By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor.
MILL FILL LEVEL CONTROL. Use the Mill Feed Rate to control the Mill Fill Level (rather than bearing pressure). The Mill Fill Level setpoint can be pushed to a safe maximum to optimise the throughput. Stabilize all Fill Level Signals (input, output, shell) for effective ''what goes in goes out'' operation. SAFETY CONTROL

In the operation of a grinding circuit you are managing several pieces of equipment as a single unit. If you make a change in the ore in the fine ore bin, that change will be reflected through the entire grinding process and beyond into the rest of the concentration system. The first thing that an operator will have to learn is to be able to tell when the rod mill is, or isn''t, grinding fine ...
