Simplifying wet grinding with AG/SAG mills AG/SAG mills are often the optimum solution for wet grinding (achieved in a slurry 50 to 80 percent solids). AG/SAG mills can accomplish the same size reduction work as two or stages of crushing and screening, a rod mill, and some or all of the work done by a ball mill.
To a more significant degree than in other comminution devices, SAG Mill Liner Design and Configuration can have a substantial effect mill performance. In general terms, lifter spacing and angle, grate open area and aperture size, and pulp lifter design and capacity must be considered.

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.
mills. The torque is transmitted to the mill directly through the magnetic field in the air gap of the motor, eliminating the gear reducer, the ringgear and the mechanical related issues faced by maintenance with ringgeared mills. In fact the rotor of the ring motor is the mill itself and the stator is built around the mill .

Optimization of mill performance by using online ball and pulp measurements Soon after a stop, a mill is a dangerous place to enter for the personnel tasked with taking measurements or samples. Crash stops are difficult to handle. The mill and all feed streams should be stopped simultaneously but, often, they are stopped around about the same time.
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.
