DESIGN OF THE KUBAKA GRINDNG CIRCUIT USING SPI AND …
benchmarking SAG and AG mills in a large number of plants. One outstanding achievement of this program (commercial development), was the discovery that in the range of ~0.4 to ~3mm T80, the energy consumed in either a SAG mill or a ball mill to make a size reduction in this range would be equal and could be estimated using Bond equations.
Mine operating costs and the potential impacts of energy ...
Daniel et al. (2010), for example, showed that the replacement of a SAG mill with a HPGR in a conventional SAG-Ball circuit may reduce grinding energy consumption by 15–20%. Taking into account additional savings, such as media and liner wear, the authors found that a grinding cost saving of 25–35% was potentially achievable with the use of ...
