Sag Mill Reject Crusher

Posted in: , on 7. Aug. 2009 - 23:41

plant: copper production

Reject: means all non crushed scats rejected from Ball Mills and SAG mill with high

work index (minimum 18.3 kWh/t)

As a note the scats of the Ball mills pass the SAG-mill circuit.

existing system: rejects with size about 30 mm reintroduce to grinding circuit.

qustion:

what is the best solution to crush rejects to about size 10mm and re-introduce to grinding circuit?

what type of crusher you suggest?

does anyone have experience about the crushing reject of sag mill in copper plants?

thanks ■

Yes, all the world's cone crusher manufacturers would be more than pleased to show how their product does the best job at recycle (scat) crushing. ■

High Pressure Grinding Rolls would do a better job that cone crushers but from the commercial point of view cone would be the way to go.
