Advanced fine-particle gravity separation
The patented REFLUX® Classifier is one of our most advanced fine particle, gravity-based separators, offering significant advantages in capacity, adaptability and efficiency. Incorporating the new “laminar high-shear-rate” mechanism, along with other advancements, our REFLUX Classifiers are both efficient and compact.
Gravity-based separation with maximum efficiency
Developed with your entire minerals processing plant in mind, the REFLUX® Classifier (RC) separates fine particles based on a difference in density or particle size.
The 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.
At the bottom of the mixing chamber, as a higher-density bed of settling solids forms, jets of incoming fluidisation water keeps it in suspension. Two pressure probes in the mixing chamber’s lower/middle section are used to measure the material’s density. The underflow contains high-density particles, and is generally coarser than the feed.
