Gearless AG/SAG Mills - Metso Automation - PDF Catalogs,

Grinding systems are a symbol of the application of brute force to extract mineral wealth from nature and are a major and critical part of any mineral processing facility. Autogenous (AG) grinding is the size reduction of material in a tumbling mill utilizing the feed material itself as grinding media.What's the Difference Between SAG Mill and Ball Mill,,Feed. Both the autogenous grinding mill and the ball mill feed parts are welded with groove and embedded inner wear-resistant lining plate. As the sag mill does not contain grinding medium, the abrasion and impact on the equipment are relatively small. The feed of the ball millPlant-site evaluations of the OPSA system for on-line,,Aug 01, 2000· The shutter speed of the video camera was set at 1/500 second for the measurement of SAG mill feed streams. Particle images from the SAG feed conveyor, line number 9, were collected and processed.
