SAG is an acronym for Semi-Autogenous 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%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.
As the grinding mill vibrates, media particle migration is experienced in both axial and transverse directions. In fact, the media migrates through the VIBRA-DRUM® Grinding Mill in a path similar to that of a rotary grinding mill without lifters, but each media particle imparts positive impact energy at …

A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
A vertical mill is a similar, and in some ways more complex device than the horizontal mill, with a much different set of media concerns, owing to the fact that it works completely differently from a horizontal mill.
The volume of grinding media in a mill is directly related to grinding efficiency. The higher the volume of grinding media the more effective the grind. Balls must be added to maintain the media load and mill power draw. The power draw increases as balls are added and decreases as media …

cement industry the ball mill was really an epoch-making breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding. Over the last three decades the vertical roller mill has become the preferred mill for grinding of raw materials.
Scope : The Media Charge_Optimal Ball Size spreadsheet was designed to estimate the ideal make-up ball size to any given grinding application, on the basis of the empirical correlations independently proposed by Ettore Azzaroni and Allis Chalmers.
