The CWL-M series centrifugal extractor manufactured by Zhengzhou Tiei Extraction has a good reputation in the industry. Their advantages are mainly reflected in the following aspects, which have led to their widespread application in chemical, pharmaceutical, environmental protection, and hydrometallurgy fields:

Core Technologies and Structural Advantages

1.Vertical Single-Stage and Multi-Stage Series Design:
Vertical structure: Small footprint, stable center of gravity, low vibration, and easy maintenance.
Countercurrent extraction: The two-phase liquids achieve efficient countercurrent contact in a high-speed centrifugal force field, resulting in much higher mass transfer efficiency than traditional equipment such as mixer settler. The stage efficiency is high, with single-stage extraction efficiency typically exceeding 90%.
Flexible multi-stage series connection: The number of stages can be flexibly connected in series according to process requirements, enabling high-difficulty, high-purity multi-stage countercurrent extraction with a compact process flow.

2.Efficient Mixing and Rapid Separation:
Through specially designed rotors and chambers, both vigorous mixing and rapid centrifugal separation processes are completed simultaneously within the centrifuge.
High separation factor: High-speed rotation generates powerful centrifugal force, enabling rapid separation of liquid-liquid systems with small density differences and those prone to emulsification, resulting in high processing capacity.
Strong demulsification capability: For material systems that easily form emulsions, the centrifugal force can effectively break down the emulsion layer, achieving clear phase separation.

3.Low Retention Volume and Fast Mass Transfer:
The equipment has a very small internal liquid volume, and the material's residence time inside the machine is extremely short.
Suitable for processing valuable, volatile, easily decomposable, or radioactive materials; minimizes material loss and ensures high safety; offers fast response time, facilitating process control and continuous production.

Operational and Economic Advantages

4.Low operating costs:
Low energy consumption: Compared to traditional extraction equipment with similar processing capacity (such as mixer-settlers), power consumption is significantly reduced.
Low reagent consumption: Due to high efficiency and minimal entrainment, the consumption of extractant and back-extraction agent is reduced.
High degree of automation: Enables fully automatic continuous operation, reducing manual operation and intervention.

Materials and Safety Advantages

5.Wide range of material options and strong corrosion resistance:
The core components (drum, contact parts) can be made from various materials depending on the corrosiveness of the materials being processed, such as stainless steel 304/316L, Hastelloy, titanium, polymer materials (such as PEEK), and engineering ceramics, offering a wide range of applications.

6.Good sealing performance, safe and environmentally friendly:
Fully enclosed operation effectively prevents the leakage of volatile, toxic, and harmful solvents, ensuring the health of operators and meeting environmental protection requirements.
Explosion-proof motors and electrical components can be used to meet the safety production requirements of flammable and explosive working conditions.

7.Convenient maintenance and long service life:
Modular design allows for easy replacement of key wear parts (such as mechanical seals).
Good dynamic balance performance ensures stable operation and long service life of bearings and other mechanical components.

Application Scenario Advantages

8.Strong processing capacity and wide range of applications:
Especially suitable for:
Systems with small density differences between the two phases.
Systems prone to emulsification.
Systems requiring short residence times.
High-value, small-batch fine chemicals and pharmaceutical products.
Large-scale industrial applications such as hydrometallurgy and wastewater treatment.

The core advantages of Zhengzhou Tiei Extraction's CWL-M centrifugal extractor can be summarized as: high efficiency, energy saving, compact design, safety, and flexibility. It utilizes a centrifugal force field to enhance mass transfer and separation, perfectly addressing the shortcomings of traditional extraction equipment such as low efficiency, large footprint, easy emulsification, high solvent loss, and significant environmental pressure. It is an ideal choice for modern continuous and refined liquid-liquid extraction processes.

When making a selection, it is recommended to conduct pilot-scale testing based on specific material characteristics (such as corrosiveness, density, viscosity, and ease of emulsification), processing volume, and separation requirements to ensure the optimal choice.
