REFLUX Classifier RC combines a conventional fluidised bed separator with a set of parallel inclined plates that form lamella channels. The feed slurry enters the RC below the lamella plates via internal feed chambers located in the lamella chamber. As the fluidised bed builds up in the mixing chamber below the feed chambers, material with a higher density than the bed will sink, whereas a material with a lower density than the bed will float

• low-density and fine particles tend to overflow from the RC lamellas in their first pass, along with the majority of the process water and any slimes
