In this context, a study was initiated to assess not only the performance of a Vertimill grinding circuit processing a copper concentrate to a particle size of 80 passing 17 m but also to provide Tasekos New Prosperity project specific design information for grinding to particle sizes below 80


grinding mills in the world. The contract comprises the design and manufacture of a 40x29 SAG mill. The mill will be driven by a Gearless Motor Drive GMD which, at 28.0MW, is equal to the largest grinding mill power ever used in the mining industry. The SAG mill design is based on Outotecs proprietary grinding

Studies on ScaleUp of Ball Mills SpringerLink

Data from ball mills with a wide range of diameters are analyzed using detailed mathematicalnumerical models. Analysis shows the relative power inefficiency of large ball mills is due to their inefficient breakage of coarse particles. The models developed can be used to scale-up mill behavior. The behavior of large mills at Bougainville and Pinto Valley is compared.
