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.

what about material effect on crusher?

Moisture (w/w)- Normal 3.5 % w/w

Moisture (w/w)- Maximum 10 % w/w

does cone crusher have problem with this humidity? if yes what is best solution?

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.
