    stage of the reflu classifier coal. The REFLUX Classifier requires only minimal operator input, with just one operational control required. Capacities up to 200 tph in coal and up to 250 tph in iron ore Nominal capacities range from 20 tonnes per hour (tph) to 200 tph in coal, and from 25 tph to 250 tph in iron ore (dependant on PSD).

  • Beneficiation of coal fines using the Reflux™ Classifier

    01/06/2019· Reflux™ Classifier (RC), one of the advance gravity separator in coal and mineral processing industries, is a combination of liquid fluidized bed, autogenous dense medium and lamella settler. In the previously published literature, the feasibility of the RC for beneficiating low ash Australian coals was analyzed. However, the sensitivity analysis of RC for various operating conditions was not critically assessed for the high ash coking coal

  • The Lamella High Shear Rate REFLUX™ Classifier

    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 finer sizes.

    The REFLUX Classifier requires only minimal operator input, with just one operational control required. Capacities up to 430 tph in coal and up to 500 tph in iron ore Nominal capacities range from 20 tonnes per hour (tph) to 430 tph in coal (-2.00 mm +0.250 mm), and from 25 tph to 500 tph in iron ore (-0.300 mm +0.075 mm).

  • Popularity of FLSmidth’s reflux classifier technology

    16/03/2017· The Reflux Classifier incorporates a “laminar high shear rate” mechanism, which represents the latest in fine particle gravity based separation technology. The lamella section enhances the efficiency/capacity of the Reflux Classifier, producing a more compact, higher efficient separation unit when compared to competing fine coal and mineral processing equipment such as spirals, up-current classifiers

  • Maceral separation from coal by the Reflux Classifier

    01/03/2016· The parent coals (the Reflux Classifier feed materials) wet-sieved to the size of − 210 + 100 μm were immersed in water at least 24 h with regular stirring prior to separation to ensure that water penetrated into the internal pores of coal particles so that there would be no occluded air that could have impact on the separation process (i.e. altering the particles apparent density).

  • Beneficiation of coal fines using the Reflux™ Classifier

    01/06/2019· Reflux™ Classifier is a combination of lamella settler, autogenous dense medium separator and fluidized bed separator (Galvin et al., 2002). The fluidized bed separator acts as the primary density based separator whereas the Lamella section acts the secondary separation zone in the Reflux™ Classifier. In the fluidization section, rising fluidization water keeps incoming coal particles in the

    around the reflux classifier (RC) and the capabilities of this equipment in coal processing. Until now, no full scale plant testwork results have been published in the Australian coal industry, and many of the claims have been uncorroborated. This paper seeks to address the gap in public domain knowledge about the reflux classifier. The application of the reflux classifier to achieve high

  • Investigation of the Reflux Classifier for Density and

    The Reflux Classifier is a new device for separating particles on the basis of either density or size. Water flows up through a distributor plate at the base, suspending particles within the vessel. A set of parallel inclined plates amplifies the segregation rates of the particles, permitting slower settling particles to pass through the zone of inclined plates while causing the faster settling particles to return to the zone

  • Pilot plant trial of the reflux classifier ScienceDirect

    01/01/2002· The Reflux Classifier produced an excellent gravity separation of −2 mm coal at a high feed throughput of 75 m 3 / m 2 h of slurry, and solids loading as high as 47 t / m 2 h. This throughput is significantly higher than achieved in a TBS. The RC features sets of parallel inclined plates that permit very much higher volumetric loadings, and therefore higher throughputs.
