The separation efficiency of reflux classifiers™ in comparison with DMC was analyzed by Galvin et al 2010(1) by comparing against a 1.0 m diameter dense media cyclone (DMC) (Weale and Swanson, 2002). The study reported that the Ep values of DMC was lower than the RC, when the particle size exceeds 2.0 m whereas the Ep value of …

The Reflux Classifier generated yield-ash curves have been shown to be in excellent agreement with conventional float-sink results for coal particles in the 0.038–0.250 mm size range. However, the dilute conditions involved in these semi-batch tests result in loss of the autogenous dense-medium effect and particle size has a larger influence.

We designed the REFLUX Classifier for safety, reliability and productivity. As a cost-effective solution in your entire process flow, the RC™ will help keep your operation …

The Reflux Classifier is a relatively new gravity separation unit that consists of a set of parallel inclined channels located above a conventional fluidized bed. In the early years, the effect of the inclined plates on particle size classification was studied using a semi-batch fluidization system [12]. A generalized empirical model involving ...

ABSTRACT A 2 m diameter REFLUX™ Classifier was tested on coal feeds up to 6 mm top size. Solids feed rate was varied from 50 to 160 t/h at suspension concentrations up to 37 wt.% solids. Performance was consistent, with product ashes below 10 wt.% for +1 mm particles and reject ashes usually exceeding 70 wt.%. The density …

The Reflux Classifier (RC), composed of a vertical fluidized section attached to a set of parallel inclined plates, is a new device for the concentration by density variation and was invented by Galvin et al.

The Reflux Classifier (RC) is an innovative device offering advantages both in separating particles according to size and density, and in solid–liquid separations.

The Reflux Classifier (RC) is a fluidized bed separator capable of operating at high hydraulic loadings due to the presence of parallel inclined plates within the system. When the fluidized suspension passes up through the inclined channels formed by the plates, faster settling particles segregate onto the inclined surfaces, and slide back down ...

The REFLUX™ Classifier is targeted at the treatment of -2.00 mm coal and is effective down to 0.125 mm. However, as noted by Galvin et al. (2010), the REFLUX™ Classifier, in common with other gravity separation devices, can show a shift in cut-point by size. This effect is pronounced with the

This work examined the potential for applying a vastly simpler approach, a single stage of gravity separation using the Reflux Classifier. Here the classified feed, 90 % finer than 0.150 mm, is sent directly to the Reflux Classifier, leading immediately to a high-grade concentrate at high solids concentration.
