In hydrometallurgy industry production, adapted centrifugal extractor with non-equilibrium extraction to extract cooper, uranium, nickel, cobalt, molybdenum.
Working principle

In hydrometallurgy industry production, adapted centrifugal extractor with non-equilibrium extraction to extract cooper, uranium, nickel, cobalt, molybdenum, rare earth metal and other metal elements, using short contact time of the two phases in centrifugal extractor, element with high speed mass transfer was extracted, and the slower was not extracted basically, that realized two elements’ separation, it will be large harder if adapted mixed clarifying tank. Tianyi centrifugal extractor used for rare metal (such as cobalt, nickel, manganese, lithium) recovery from waste lithium battery, lithium extraction from brine and so many hydrometallurgy industry.
Aiming at the disadvantages of traditional centrifugal extractor, Zhengzhou Tianyi Extraction Technology Co.,Ltd. bring out CWL-M series centrifugal extractor, and own independent intellectual property rights , patent number :ZL2014205865573. Under the same handling capacity condition, this machine power consumption is only 10%~30% of traditional anular type, at the same time, short duration of this machine, split phase quickly, high extraction rate, save cost and solvent could be recycled and reused.
Hydrometallurgy extraction technology:
Product category:
multistage counter -current extraction device, multistage cross current extraction device, single stage centrifugal extractor.

Customization or not: Yes
If supply small test or pilot-plant test: Yes
Centrifugal Extractor Working Pinciple:
 1. Mixing and mass transfer process:
Light and heavy liquor enter in the annulus mixed zone proportionally and from two different feed pipe orifice respectively, which formed by bowl and shell, with the help of bowl’s rotation, the two phases through turbine disc and impeller mixing and dispersing quickly, after mass transfer completely, to finish mass transfer process.
2. Two phases separation process
With the eddy-current disc help, mixture enter in bowl, at the compartment formed by board, the mixture is quickly synchronized with the bowl, under the action of centrifugal force, the larger density liquor moving away from the bowl center to the wall gradually in the upward flow; and the small density liquor doing the opposite, after clarification, two liquids enter into collection chamber with their own weir plate respectively, and drawn out by tigella, to finish the separation process.  

Extractor advantages: :


   Separation effect is obvious and large handling capacity; 

●  Two phase materials contact with short time, and save extraction agent consumption and save cost; 

●  High mass transfer rate, high stage efficiency, convenient start and stop, it can not break balance when stopped.

●  Cover small area, the cost of comprehensive investment is low. 

●  Well-adapted, good flexibility, with intermittent operation, or single operation, or continuous counter current operation, and there is no need to add interstage pump.
