Contact us if you are planning to use a SAG Mill for your grinding circuit.

Plan right now and be certain your grinding circuit will be ready to achieve production targets. Starkey & Associates’ SAGDesign test ensures your mine will be well positioned to achieve scheduled production by offering uncompromising precision while meeting any company’s testing budget.

Inherently accurate, SAGDesign testing is based on ore from your mine, unlike other proprietary methods that use overcomplicated modeling based upon samples and results from somebody else’s mine. SAGDesign differs from these black box methods by being an open technology encouraging better dialogue and understanding between our clients and us – a level of transparency not seen since Autogeneous grinding was introduced in the 1950’s.

SAGDesign testing can be used at any phase of the design or optimization process, whether it is specifying the dimensions and power requirements for a new mill order, benchmarking, or predicting throughput in existing circuits. Founded upon John Starkey’s practical engineering experience, Dawson Metallurgical Laboratory’s expertise and Outotec’s backing, a straightforward first principles approach to mill design was created. SAGDesign testing is complimented by full service capabilities including onsite sampling supervision and an international network of equipment-ready and certified laboratories. It is also the only testing program in the world reliable enough to be used as the basis for Outotec’s throughput and grind guarantee for Outotec mills.

The SAGDesign test program can be scaled to your project budget. In most cases, analysis can be developed from existing drill core samples and requires only 10 tests to get a correct design, which is not only attractive from a total cost perspective, but dramatically reduces the turnaround time – no more waiting to get your order in the mill procurement and assembly queue sacrificing months of productivity.
