Request PDF Efficiency of raking in gravity thickeners There is little published literature on the design and operation of rakes in gravity thickeners In practice, design principles and The Raking Efficiency (RF) is of order 1 (although it fluctuates over the tank radius) which we will see is consistent with the behaviour in fullscale thickeners The similarity in predicted efficiency measures between pilotscale and fullscale that will be seen in the following sections suggests that raking in the pilotscale unit is similar 101016/jminpro201003007 DeepDyveEfficiency of raking in gravity thickeners ScienceDirect Jul 01, ;32;Each efficiency measure is related to different aspects of rake design and operation: the underflow fraction indicates the likelihood of excessive draw down and rat holing or over delivery at the underflow; raking efficiency provides useful information on the detailed design of individual rake blades; raking efficiency of raking in gravity thickenersIn this paper we define and discuss a range of efficiency measures that allow different aspects of raking in gravity thickeners to be quantified to the use of raking efficiency measures is a Raking in gravity thickeners Request PDFRaking in gravity thickeners Int J at 8% solids increased flocculant to 22 ppm in Miner Process 2008; 30 8 Rudman M, Paterson DA, Simic K Efficiency of settling rate In all experiments, the transition raking in gravity thickeners(PDF) Increasing efficiency of thickener operation in
