In a cyclone, a higher feed density is analogous to a higher density (= more particles) in the glass of slurry. Particles will find it harder to sink so that only the large, heavy particles will make it to the wall. On the other hand, a lower feed density will allow the smaller, lighter particles to sink, reducing the cut point.
