What’s the difference of Ball mill, SAG mill, AG mill?

2018-1-11  Attrition mill is a type of grinding mill by kinds of media to crush lump to powder-like substances. The impact can be rock on rock such as in an Autogenous Grinding (AG) mill, rock and a small ball charge (~10%), used in Semi Autogenous Grinding (SAG) mills, balls of various sizes in Ball Mills and less commonly these days, steel rods in Rod Mills.

SAG Mill Autogenous and Semi-Autogenous Mills

SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in the mill. Via the use of sophisticated instruments and software, we closely monitor the mill

Autogenous and Semi-Autogenous Mills ScienceDirect

2016-1-1  The AG/SAG mills generally receive ore directly from the crushing plants with alternative arrangements made to receive ore from a stockpile. In rare cases, the feed is directly from the mine. Schematic diagrams of a typical semi-autogenous mill with large D/L ratio and a square mill are illustrated in Figure 9.1, Figure 9.2.

What's the Difference Between SAG Mill and Ball Mill

2019-11-26  SAG mill grind ores through impact, attrition, abrasion forces. In practice, for a given ore and equal processing conditions, the AG milling has a finer grind than SAG mills. How does a sag mill work? The working principle of the self-grinding machine is basically the same as the ball mill, the biggest difference is that the sag grinding

Dynamic Modeling and Simulation of SAG Mill Circuits

AG/SAG mill is inefficient in grinding particles of a certain size, typically in the range of 25-55 mm, i.e., pebbles. Therefore, cone crushers are often used as pebble crushers and integrated into AG/SAG mill circuits to break the critical size particles that accumulate in the mill and to increase the performance of the primary grinding circuits.
