Thickeners Thickeners — or Clarifiers, depending on the application — can be used to recover immediately reusable process water, as well as extract fines and other materials Thickeners can be used by mineral and aggregate producers, as well as by environmental contractors in industries such as wastewater management
Thickener consist of a tank for introducing the feed with minimum turbulence and a drive actuated rake mechanism for moving settled solids to discharge point for removing thickened solids, and removing clarified liqu Bridge supported centrally driven thickeners are common up to 15 m dia side given figure shows a typical unit
The thickener rake mechanism obviously would have to handle this By Allan Waters very viscous slurry, and extreme raking loads could be expected It was anti cipated that this load would exceed the High Dens' 'ty Red Mud capability of any centre drive machine, and a peripheral (traction) drive was Residue Thickeners selected
As the rakes are turned by the drive shaft they cause the concentrate that has settled onto the bottom of the thickener to be pulled into the discharge chamber at the centre of the thickener This is called the CONE It is from this cone that the thickener underflow is taken During normal operations of the circuit, the thickener may be pulled .
Thickener – TYPE SPT – A BRIDGE MOUNTED CENTRAL DRIVEN TYPE Bridge truss spans the full diameter of the tank Feed well, drive and rake mechanism are supported by the bridge truss Worm and worm wheel type drive head powers and vertical centre shaft carry the rake arms Feed enters through the central feed well
GNZ centre drive efficient thickener is a kind of new-style solid-liquid separation equipment, and is designed by our company with the introduction of foreign advanced technology The thickener has multiple national patents such as center drive, high-efficiency ,
The job of the EUROPELEC CENTRAL DRIVE THICKENER is to thicken sludge from municipal or industrial wastewater treatment plants It can be used in small or medium-sized installations Effluent is channelled to the centre of the tank in the influent well where it is spread evenly and without turbulence over the thickening zone The clean effluent .
