To monitor and respond to critical impacts and changing conditions such as liner wear and ore variation, ECS/ ProcessExpert uses LoadIQ which is a self-powered smart sensor attached to the mill shell. Conditions inside your mill are automatically adjusted to minimise liner damage, stabilise and then optimise the operation of a SAG Mill.

Outotec has recently been awarded a contract to deliver one of the largest grinding mills in the world. The contract includes the design and manufacture of a Ø 40' x 29' SAG mill. The mill will be driven by a Gearless Motor Drive (GMD) which at 28.0 MW is equal to the largest grinding mill power ever used in the mining industry. The SAG ...

The two installed mills include a semi-autogenous (SAG) mill measuring 10.4 x 6.1 m with a drive output of 15 MW; and a ball mill rated at 18 MW. The SAG mill reduces ore fragments with a maximum size of 250 mm (P80 = 152 mm) down to 2 mm, and the ball mill reduces the SAG mill product to about 74 µm. Grinding is followed by flotation.

Some consultants have the view that the gear drive is limited in power. Mr Craig Denecki (Falk Milwaukee) in his paper, presented at the 1996 SAG mill conference, provided details of the then largest gear drive in operation on a SAG mill (34ft x 18ft) at Escondida 13.4MW, which began operation in 1995. The reason for not having larger gear drives

Typical gear driven mill and gearless mill with a ringmo-tor are shown in Figs. 1 and 2. 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 ...

FFE gives the mill details thus: 8.23 metres inside shell diameter; 12.19 metres effective grinding length; 12.8 metres between flanges; and dual 7,000 motors. That makes it the largest low-aspect, dual-pinion gear-driven mill ever to be designed and built. The new mill has an annual throughput of 4.2 million tons of ore.

Increasing the size of the mills, however, meant that Cadia would need to use mills of unproven design {40 ft x 20 ft (12.2 m x 6.1 m) SAG mill and 22 ft x 33.5 ft (6.7 m x 10.2 m) ball mills}. There was considerable concern about taking this step, as many saw this as a risky option in the Cadia Feasibility Study performed by Fluor Daniel-Davy.
