Web25 Mar 2015 · In this contribution, the impact of specific features of the Bürger-Diehl model on settler underflow concentration predictions, plant sludge inventory and mixed liquor suspended solids based control actions are investigated by using the benchmark simulation model no. 1. The numerical results show that the Bürger-Diehl model allows for more ... Webwould be used on a similarly sized thickener producing a "normal" underflow concentration. In addition, the design criteria for the drive is significantly different from normal minerals duty. The torque will be consistently high, but will not be subject to as many peaks. Due to the high pulp depth, there is not much to

WebThis work describes the concentration of iron ore slimes on a pilot scale by using a 500-mm diameter flotation column and a novel collector, which renders the use of a depressant unnecessary. The pilot column was operated in series with the industrial plant Vargem Grande 2 (Iron Quadrangle, Brazil) receiving, as feed, part of the underflow from the … Web7 Nov 2024 · The underflow concentration is a function of the ore supply and the underflow rate. Liu ( 2007) proposed that the underflow concentration of the thickener is determined …
WebThe problem with using a conventional valve or orifice to control underflow concentration lies in the fact that these flow restrictors are typically insensitive to viscosity. The … Web4 Sep 2024 · 3. Abnormal underflow concentration and discharge. The operator should frequently observe the underflow discharge status of the cyclone, and regularly check the underflow concentration and fineness. Cause: The high underflow concentration may be caused by the large feed slurry concentration or the too small underflow orifice.
