Wet Autogenous Grinding in Tumbling Mills

Jul 04, 2019  Autogenous Grinding Mechanisms Autogenous grinding is at present carried out in tumbling mills of the same types as used in ball mill grinding. The similarities in equipment and procedure have led to the commonly held assumption that the grinding mechanisms are the same in the two processes, with the coarse part of the ore charge taking over ...

Differential mechanisms of failure of autogenous and non ...

Thus, the mechanisms underlying the late failure of autogenous and non-autogenous grafts differ markedly; autogenous grafts most commonly fail as a result of the gradual development of lesions intrinsic to the graft, while non-autogenous grafts fail precipitously, presumably as a result of some non-anatomic mechanism.

Autogenous and Semi-Autogenous Mills FLSmidth

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.
