Drum-type separator is of shallow-groove type and the suspension liquid is shallow. The agitation by the drum will keep the suspension liquid density stable. The discharge chute is wide enough to discharge coarse ore. However, the strong agitation will affect settling of fine particles, so this separator is not suitable for fine particle ore.

The larger ore that is on the bottom will not be flowing as fast as the light ore on top. To separate the two, the rakes and the spiral will pull the all of the slurry back up the incline, then, let it go to flow back down towards the underflow or in this case the fine ore discharge point. The smaller, faster ore will be able to travel a longer ...
