Jul 01, 2014· This paper describes the first pilot scale trial of the Reflux Classifier (RC) to separate iron oxide and silica particles less than 106 μm. The equipment used to perform the tests was the pilot scale unit RC300 (0.29 m × 0.29 m) from -Ludowici. The flowsheet used for the RC tests is presented in Fig. 2. As illustrated, a homogeneous pulp was prepared in the conditioner (3) and then
Jan 01 2002The Ludowici LMPE Reflux Classifier is a new device designed for classifying and separating particles on the basis of size or density This work presents a series of experimental results obtained from the first pilot scale study of the reflux classifier (RC) The main focus of the investigation was to assess the particle gravity separation and throughput performance of the device In this
Aug 01, 2015· A pilot scale Inverted Reflux Classifier was used to separate cenospheres from fly ash waste, following successful studies at a laboratory scale (Kiani et al., 2014, Kiani et al., 2015). The product grade and the cenosphere recovery responded to changes in the feed split ratio in accordance with the earlier study.
Correlating laboratory and pilot scale reflux classification of fine coal is my own unaided original work. It is herewith submitted in partial fulfilment of the requirements for the degree of Magister in Chemical Engineering to the North-West University of the Potchefstroom campus.
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 to the zone below, while slower settling particles pass on through.
REFLUX classifier incorporates the new ‘laminar high shear rate’ mechanism the latest in fine particle gravity based separation technology. This, along with advancements in channel spacing and width mean that REFLUX classifiers are more efficient and more compact than competing fine coal and mineral processing equipment. How it works A REFLUXclassifier separates small
Kevin P Galvin. The REFLUX™ Classifier (RC™) consists of a fluidized bed housing, with a system of parallel inclined channels above. This system performs a simultaneous gravity separation and
The Reflux Classifier provides a method of hydrosizing at solids throughputs of up to about 20 t/m2-h. We believe this throughput to be significantly higher than could be achieved if a teetered bed separator was to be used for hydrosizing. In general, a similar level of performance was observed at

Recent developments have shown that the reflux classifier can successfully be used on Australian coals, and based on that, a number of pilot plant investigations have been done in South Africa. While pilot scale units are usually used to test the applicability of a new technology on specific coals, a need exists to gather more fundamental data
Two pilot-scale Reflux Classifiers (600 mm × 600 mm cross-section) arranged in a cascading sequence were used to beneficiate fine -2 mm coal. The first Reflux Classifier performed a density separation that produced a coal product contaminated with fine high-ash slimes. This was then washed in the second Reflux Classifier to remove the fine
REFLUX classifier incorporates the new ‘laminar high shear rate’ mechanism the latest in fine particle gravity based separation technology. This, along with Pilot scale testing available • Pilot scale RC300 units available for rental • The RC300 is designed for in-plant test work in coal and mineral
The Ludowici LMPE Reflux Classifier is a new device designed for classifying and separating particles on the basis of size or density. This work presents a series of experimental results obtained from the first pilot scale study of the reflux classifier (RC).
Both laboratory and pilot-scale units displayed similar behaviour and the results were also consistent with existing correlations for negatively-buoyant particles in the standard Reflux Classifier.
