  • Pebble Crushing in SAG Mill Circuit 911 Metallurgist

    · The pebble crushing test circuit as originally designed extracted a minus 76 mm (3 in) product from the fully autogenous mill through 76 mm (3 in) squareThe SAG circuit was built without a pebble crusher and the mill was rejecting approximately 50T/hour of ungrindable pebbles Over 5 years, 650,000 tonnes of gold bearing pebbles had been milled, rejected and stockpiled The objective was to crush the existing 50t/hour pebble stream and to reprocess the 650kT pebble stockpilepebble crusher sag ProductsA pebble crusher is the way to go for a greenfields project SAG mill grates generally limit pebble extraction rates to around 25%, so you can't expect a throughput increase of more than 510% depending on the ore To pebble crush, you need to port the grateSAG Circuit Design Crushing, Screening & Conveying

  • SAG mill and Pebble mill Grinding & Classification

    SAG mills will contain some degree of steel media, generally 8 12% SAG Mills tend to have large diameters and short lengths Pebble Mills, also called Tube Mills, use pebbles to grind grit to powder, and are long Mills with a small diameters Pebble Mills contain no steel grinding media· b) Semi autogenous grinding in which the pebble fraction of mill discharge (+½ in) is taken out through pebble ports for separate crushing and ball milling The minus ½ in fraction of mill discharge is recycled to the SAG mill through a classifier The circuit is called SACB: Semi autogenous/ Crusher/Ball millCrushing SAG Mill Critical Size MaterialPebble crushers are commonly used in autogenous and semiautegous (AG/SAG) mills, as they area much more efficient user of power on this material thereby reducing theINVESTIGATION OF SORTING TECHNOLOGY TO REMOVE HARD
