Aug 25, 2014· In our recent conversation, Prof. Alban Lynch was very sceptical about where semi-autogenous grinding (SAG) mills have gone, and thinks they have taken us along the wrong track. He feels that they may be attractive in terms of high productivity, but says that "their energy efficiency is poor, and I feel that these immense machines are going to turn into very large ball mills".

Another common name is “off-the-shelf” solutions, which is a misnomer since these systems require a considerable amount of setup and configuration. SAG mill control fundamentally means managing the load in the mill by adjusting the feed rate of ore to the mill and/or manipulating the rotational speed of the mill.
Fully autogenous and semi-autogenous mills as aggregates can be used to pregrind minerals and ores and to grind waste, e.g., bulky waste. AG and SAG mills can be designed for dry or wet grinding. The bearings are hydrostatic slide or slide shoe bearings. Usually, AG and SAG mills have a …
AG/SAG Mill The Autogenous/Semi-autogenous Grinding Mills are in most cases used as primary crushers. AG Crushers use the ore exclusively as their grinding media. In case the hardness and the abrasiveness of the Ore is not suitable enough to carry out the grinding process, steel balls are added in-order to assist the process; these are called ...
