He notes that FL has supplied at least 20 projects globally with bolted thickener tanks, putting close to 40 of these units into the market in recent years. The largest unit was a 45 m diameter high-rate thickener, while the more specialised deep cone thickeners have also been built in this way up to a size of 35 m in diameter.
Supporting the additional load requires a much more robust tank design. Moving thickened mud of up to 10 times the yield stress requires a mechanical drive and rake structure capable of 10 times the torque. It is therefore not usual for a Paste Thickener to cost two to three times that of a High-Rate Thickener.
99.6%. Under our assumptions, a three-stage CCD circuit using paste thickeners outperforms a four-stage CCD with high-rate thickeners (97.6% vs 96.2%). The process choice is clear, unless high volumes of wash water are justifiable; which of course depends greatly on the values contained in the pregnant liquor.
EIMCO and Dorr-Oliver thickeners are available in both bridge-supported and column-supported designs. We offer beam- or truss-type bridges, depending on thickener diameter. In the bridge-supported design, suitable for thickeners up to 50 m in diameter, the drive is supported by the bridge, driving the rakes with a centre shaft.. Column …
The objective of a thickener is to separate low-density slurries into a relatively clear liquid and a high-density slurry, or sludge. All thickeners depend on gravity to allow for settling fine solids. A thickener consists of a circular tank with a gradually sloping cone-shaped bottom with a discharge in the center.
