What's the Difference Between SAG Mill and Ball Mill

The working principle of the self-grinding machine is basically the same as the ball mill, the biggest difference is that the sag grinding 


Describe in detail SAG mill circuits of large-scale plants and the benefits of each. - Detail the issues occurred during SAG mill operation: blockage of grates, cracking of bolts, liners and grates, flowback, carry over; blockage and breakage of meshes from trommel and screen, among other relevant issues.

SAG Mill Grinding Circuit Design - Mineral Processing & Metallurgy

SAG mill operation is more dynamic, and typically requires a higher degree of process control sophistication. Though more complex in AG/ SAG circuits relative to the crushing plants they have largely replaced, these issues are well understood in contemporary applications.

Operation Of Sag Mill

operation of SAG mills. SAG mills are currently the technology of choice in hard rock milling operations for reducing primary-crushed ore to ball mill feed. In recent years, the trend has been towards larger-sized SAG mills with diameters of 10.4 m 34 ft and above, with the largest being 12.2 m 40 ft in

SAG Mill Process Control - Grinding & Classification Circuits

The purpose of a grinding mill is to convert electrical energy into rock breakage. The best use of that asset is to try to maximize the power draw. Try to hold the mill speed high and vary the feed rate to hold the weight (or bearing pressure), but watch out for "cycling" or "surging" that indicates instability in the charge.
