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 discharge cone.
Thickener Manufacturer, Mumbai, India. ... Connected with the rake arms for the outer annular area are cone scraper blades which keep the underflow solids in the centre of the tank in motion for ease of withdrawal. Read More . How a Thickener Works Mineral Processing Metallurgy.
A Deep cone thickener of 20 m is used to thicken the pulp to above 63 % solids in weight before feeding the reactor tank where it is dissolved by sulfuric acid. Use of Deep Cone Thickener has allowed an optimization of Sulfuric acid consumption during the leaching process and allows a better attack reaction by using a pulp more thickened than ...

The stirring device is installed in the center of tiled plate thickener; the vibrator is installed on the outer wall of cone to accelerate the thickening and avoid ...
The underflow cone is slightly bent, but this is rather easy to repair. Deflector cone scraper has been cut off, possibly because it was difficult to unbolt. New scraper is required. The rakearms are in good condition. They were piled on one of the access stair structures.
In this case the pattern would be a deep cone thickener equal to the existing paste thickeners, having dimensions of 10 meters in diameter and 14 meters high in the shell side, which had a scraper mechanism, and which was obtaining a solids content of 30 to 21 underflow in wt% compared to 15-17% obtained in conventional thickeners.
Deep cone thickener (DCT) is key equipment in cemented paste backfill (CPB) technology. However, rake blockage occurs frequently in DCT during the dewatering process of the unclassified tailings being thickened from dilute slurry to thickened tailings or paste. Rake blockage has disastrous effects on the CPB operation. In order to investigate the influencing factors of rake …
The underflow gangue (waste) from the rougher and scavenger cells flows to a tailings thickener to recover water for the process. Filters dewater these tails further, or a tailings pond stores them. Bulk (Copper-Moly) Thickener. A high-rate thickener dewaters the bulk of copper-moly concentrate before more separation. Moly Flotation

Maximizing thickener underflow density has advantages in many of the traditional thickener applications. There is a long history of innovations in thickener design to enable the production of higher densities. Large High Density thickeners were pioneered in the late 1980's. The roots of the FL Deep Cone thickeners go back to the 1960's.

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.
Recent improvements, however, in the design of solid bowl conveyor units and disc units may alter this situation. 4.2 The Gravity Thickejner A conventional gravity thickener is shown in Figure 4-4. The thickener normally consists of two truss-type steel scraper arms mounted on a hollow pipe shaft keyed to a motorized hoist mechanism.
The rake arm rotates slowly with the scraper blades on the bottom to push the solids in the thickener to the deflector cone. The deflector cone is the cone shaped discharged located in the center of the thickener. Once the solids enter the deflector cone, they are removed by pumps, pumping the concentrated solid underflow to a conditioning tank.
