Crushing and Grinding Wet & Sticky Ore
The fines from the grizzly and the crusher discharge pass by gravity and/or conveyor to a Combination Scrubber and Trommel. Here, further scrubbing and washing takes place to separate the ore into two fractions, usually plus and minus ½ inch. The coarse washed fraction is further reduced in a Secondary Cone Crusher without difficulty.

Both drums and discs ball the ore to about 9-16mm size. Drums typically have very high recycle rates so have a screening circuit to screen out undersize and oversize pieces to be put back through the drum. Discs usually do not have a separate screening circuit at the disc. Green pellets are then transported to the induration process.
