In the hydrometallurgical process, through the extraction of metal elements such as copper, uranium, nickel, cobalt, molybdenum, and rare earth, hydrometallurgical centrifugal extractors are used for non-equilibrium extraction. Through the short contact of the two phases in the centrifugal extractor, an element with a fast mass transfer speed is extracted, while an element with a slow mass transfer speed is basically not extracted, which makes the separation of the two elements very difficult when using a mixed clarification tank.

The CWL-M series centrifugal extractor is developed to solve the shortcomings of traditional centrifugal extractors. Under the same processing capacity, its power consumption is only 10%-30% of the annular gap type. At the same time, the centrifugal extractor developed has a short retention time, fast phase separation speed, and high extraction efficiency, saving investment costs and solvent recovery and regeneration costs.

Performance characteristics:

1. Simple structure and good stability-adopting an upper suspension single-point structure, there is no bottom bearing and mechanical seal in the processing area, and no leakage will occur, solving the problems of frequent failures and short service life of centrifugal extractors and reducing equipment maintenance costs.

2. Energy saving - larger processing capacity and more energy saving (under the same processing capacity, the power consumption is 1/10~1/3 of the traditional annular gap structure centrifugal extractor).

3. Corrosion resistance - the equipment can be made of perfluorinated polymer materials, which can effectively resist strong acid (hydrochloric acid, mixed acid, etc.) erosion.

4. Good mixing and separation effect - a variety of mixing structures can be selected, with good separation effect, suitable for easy emulsification system.

5. Convenient replacement of heavy phase weir plate - when the liquid system changes, the heavy phase weir plate can be quickly replaced, and the operation is simple.

6. Small liquid storage capacity of the equipment - the effective volume of the equipment is small.

7. High degree of automation - it can monitor the production process in real time online, and can be equipped with an online cleaning system according to GMP requirements, which is completely suitable for intermittent and continuous operation.

Compared with the traditional extractor, the CWL-M hydrometallurgical centrifugal extractor of the present invention has the advantages of small footprint and small equipment filling volume. Good airtightness and no odor.
