Dynamic modeling and simulation of a SAG mill-pebble

Oct 01, 2018The first graph shows that the throughput of the SAG mills is affected by the pebble crusher settings. A cone crusher with settings like CSS = 28 [mm] and speed = 280 [rpm] gives coarser product than a cone crusher with smaller CSS and higher eccentric speed. The crusher’s capacity with a larger CSS and lower speed is higher than with a small

Pebble Crushing in SAG Mill Circuit

Full Scale Test Circuit Based upon the results of the pilot plant test work, a decision was made to conduct a full scale test in 1990 utilizing one of the ten (10) primary mill lines at the National Steel Pellet Plant. Primary Mill Line No. 10 would be converted to a fully autogenous grinding mill with pebble extraction and crushing. Engineering and installation of the test circuit was
