Autogenous and SemiAutogenous Mills | FL

Rely on our proven track record of SAG and AG Mill superiority. Since the early 1980s, we have been designing and manufacturing SemiAutogenous (SAG) and Autogenous (AG) Grinding Mills under the FullerTraylor brand. Semiautogenous grinding uses a minimal ball charge in the range of 615% while autogenous grinding uses ore only.

Performance enhancement tools for grinding mills SAIMM

movement within SAG mills. The concepts for operating SAG mills have been inherited almost entirely from conventional ball mills. However, these mills operated under a constant ball load and at a fixed speed, the slurry load and properties being the main sources of concern. Under these relatively stable

Cortez Gold SAG Mill Optimization | KnowledgeScape

We have implemented SAG and ball mill expert control solutions and thickener control in the past at cortez. Below are the results from the SAG mill optimization. SAG mill throughput was increased by %. It is interesting to note that the expert control of the SAG mill alone yielded a 6% increase.

SAG Mill Testing Test Procedures to Characterize Ore ...

mill. As such, primary ball mills should be designed with the rod mill work index, and singlestage ball mills should be with both the rod mill and ball mill indices. This is because it is common to observe a difference (sometimes significant) between the rod mill and ball mill index values for a given ore type (McKen, Verret, Williams, 2006). On

MEI Blog: Where are SAG mills going? Barry A. Wills

Aug 25, 2014· In our recent conversation, Prof. Alban Lynch was very sceptical about where semiautogenous 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".

Grinding Mill an overview | ScienceDirect Topics

The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol ...
