MEI's Barry Wills: The impact of milling costs on total mine operating
It has been shown, for example, 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, it was found that a grinding cost saving of 25–35% was potentially achievable with the use of HPGRs in such conventional circuits.

The mills deliberately crown their work rolls slightly larger in the center to allow for deflection and compression under load. The amount of roll crown that is added is a compromise, a best guess. In addition, mills can control the gap profile by bending these huge rolls or by expanding them with hydraulic pressure like a huge steel balloon.
