Autogenous and Semi-Autogenous Mills FLSmidth

Since the early 1980s, we have been designing and manufacturing Semi-Autogenous (SAG) and Autogenous (AG) Grinding Mills under the Fuller-Traylor brand. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only. SAG

MEI's Barry Wills: The impact of milling costs on total

2014-1-6  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

Energy and Cost Comparisons of HPGR-based Circuits

2020-4-8  At a grind of 80% passing 160 μm, the HPGR-ball mill circuit shows significant cost advantage over the SABC circuit with a NPV of $33 million and an IRR of 22% (See Table 4). At a product size of 80% passing 75 μm, both options have costs advantages over the SABC option, although the HPGR-ball mill circuit had lower overall costs than the two-stage HPGR-stirred mill

Comminution circuits for gold ore processing

2005-1-1  Publisher Summary. For the vast majority of ounces of gold produced, comminution costs in the form of power, grinding media, and liners represent the single largest cost category of milling. Since, semi-autogenous grinding (SAG) ball-mill circuits represent the single largest type of gold milling comminution circuits, the chapter focuses on SAG.
