indication of higher underflow density or deeper mud bed, although it can also be caused by a higher fraction of coarse material as well as a number of other phenomon, such as islands. Rake torque measurement is usually provided by the thickener manufacturer. Typical methods
Integrated tailings solution offering transport from plant tailings outlet to a remote Tailing Storage Facility, with an integrated thickener and a ® or ® underflow pipeline pumping system. Low maintenance and rugged mechanisms (drive, rakes) Optimised feedwell for best settling rate; Engineer to order system with following options
Corrections. In Table I of the July article, "improve Clarifier and Thickener Design and Operation," by Joel Christian (pp. 50-56), the titles Vi and TSS are reversed. The first TSS is 3.1 and the first Vi is 6.045. In the overloaded case on p. 55, the underflow c oncentration should be 240 kg/m 3, not 140.
The dense Thickener solids are raked to the thickener's underflow cone and are removed via a slurry pump through the underflow pipe. Underflow slurry densities can vary based on the type of material being processed, size distribution of solids being settled, or other process factors but as a general rule, range from 35-50% solids by weight.
Tailings Paste Thickening. The advantages of paste thickeners in tailings circuits have been well-established for most minerals. The type of paste thickener underflow generally used for surface stacking of tailings is called "thickened tailings.". Thickened tailings are a suspension of solids which are relatively non-settling and non ...
The underflow density is important in maintaining stable operation and avoiding tailings block in the thickener discharge outlet. Underflow rate: A volumetric in-line flow meter can interact with a density meter and the flow meter presents a dry solids mass flow …
The blades also assist the compaction of the settled particles and produce a thicker underflow than can be achieved by simple settling. The solids in the thickener move continuously downwards, and then inwards towards the thickened underflow outlet, while the liquid moves upwards and radially outwards.
for sludge treatment for wastewater treatment plants. drum thickener. ThickTech™. The ThickTech™ Rotary Drum Thickener (RDT) is the industry leading sludge thickener. Its performance is unmatched, with sludge volume reduction of 90% and a 98% capture rate.
thickener tank EIMCO KCP Thickener tanks are constructed either from bolted / steel welded or concrete. Most of the chemical process industries prefer the steel tanks construction since they may be elevated above ground level, allow inspection of the tank's floor for leakages and bring the underflow slurry pumps nearer to the outlet of the ...
Description. Conventional Thickeners are generally incorporated in heavy duty applications when the underflow density is high and substantial torques are required to convey the settled solids from the periphery to the central outlet for pumping away.
the thickener operation there are three important process control variables for effective performance and are responsible for measuring the flow rate in three thickener applications: the feed, the underflow discharge, and in the clear water outlet in the overflow.
Thickener tanks are circular in design with a conically shaped-centre. The tanks vary considerably in size. Fluid enters the thickener tank via an overhead pipe and down into the centre of the tank. At the bottom of the tank rotating rakes help the solids settle and draw the silt towards the centre of the tank.
The diaphragm Thickener Underflow Pump is essentially one for low lifts and is particularly adapted to handle metallurgical pulps economically and with minimum attention. The Dorrco diaphragm pump was developed primarily as a means of controlling the density of the underflow from the Dorr thickener in the first continuous treatment of cyanide pulps. It has been proved the most …
Pumping Thickener Underflow Slurries. Concentrate Slurry containing a abrasive materials from three areas including very abrasive high grade nickel concentrate, mixture of copper and nickel and copper slurry with low nickel, flows up to 359 l/min (95 US GPM), up to 72% solids density of 4.29 - 4.97. 3 x VF80 pumps were initially purchased to ...
Behaviour when Model is OFF. If the user disables the unit, by un-ticking the On tick box, then the following actions occur: . The field MassFracToUF becomes visible and the user may set the fraction of the feed stream that reports to the 'Underflow' outlet. The default is . All streams connected to the unit will flow out of the 'Underflow' outlet, unless the user has changed the above ...
