  • Autogenous and Semi-Autogenous Mills FL

    Rely on our proven track record of SAG and AG Mill superiority. 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.
