MacPherson correlated Autogenous Work Index (AWi). A particle size analysis of the mill ore charge at the end of the tests provides insight into the build up of critical sized material within the mill. The AWiis used in conjunction with other Bond Work Indices (CWi, RWi, BWi) to determine power requirements using Bond's Third Law of Comminution.
In view of this, the present work accesses these factors individually and discusses what may lead a particular circuit configuration to be more or less efficient in terms of energy and costs.

Wood's scope of work includes engineering, procurement and construction management for the addition of a new downstream processing plant fed by milled product from the semiautogenous grinding mill installed during the initial expansion.
SAG mills use larger pieces of ore to break up the smaller pieces (autogenous — does it by itself). The larger pieces break down as well. The larger pieces break down as well. To help the process along, eightinchdiameter steel balls are added to the rocks as they tumble inside the rotating mill (semiautogenous — gets some help from the steel balls).

May 10, 2017· Principle of SAG Mill operation SAG is an acronym for SemiAutogenous Grinding SAG mills are autogenous mills but use grinding balls like a ball mill A SAG mill is usually a primary or first stage grinder SAG mills use a ball charge of 8 to 21% operating principles milling sand washing machine.
Rod mills normally carry 35 to 65% rod charge by volume. The limits on charge level are (1) keeping the feed end trunnion open so that feed will get into the mill, and (2) keeping the rod charge low so rods will not work their way into discharge openings where they can cause rod tangling.
