300ml PTFE Mixer Settler

Description Of  PTFE Mixer Settler 

The 300ml PTFE mixer settler  is a high-performance device designed specifically for small-scale extraction experiments in the laboratory. With high-quality PTFE, it is high corrosion resistance, high-temperature resistance, and chemical stability, effectively resisting the erosion of various strong acids, strong alkalis, and organic solvents, ensuring the safety and purity of the experimental process.

Mixer settler is widely used in the separation and purification of metals in hydrometallurgical solvent extraction processes. It consists of a mixing chamber that continuously feeds and stirs, and a clarification chamber that relies on gravity to separate liquid phases.
In practice, multi-stage series connection is often used to achieve deep separation of targets. Under certain process conditions, the mass transfer efficiency of the mixing chamber is related to the mixing intensity of the stirring paddle and the contact time of the two phases, while the clarification effect is related to the viscosity, density, surface tension, droplet diameter, clarification area, etc. of the two-phase liquid. Clarification about time.


Work Process Of PTFE Mixer Settler 

Mixed mass transfer process

The extraction agent and material liquid enter the submersible chamber or manifold from the bottom of the extraction tank in a certain proportion, and are sucked into the mixing chamber by the wheeled stirring paddle and sheared, mixed and dispersed. At this time, the two-phase liquid is fully mixed, so that the solute is transferred from one phase to the other. The liquid is transferred to another phase of liquid, thereby completing the mixed mass transfer process.

Two-phase Separation process

The mixed liquid overflows from the mixing chamber to the clarification chamber. Due to the different densities of the two phases, the separation of the two phases is completed under the action of gravity. The separated two-phase liquid flows out through the light and heavy phase weirs respectively or enters the next stage.  
Features Of PTFE Mixer Settler 
 

• Simple structure: The mixer settler generally consists of a cell body, an interface adjustment tube, a motor reducer, a stirring shaft, a stirring paddle, a speed regulator, a movable platform, etc. The structure is relatively simple;
• Stable operation and strong adaptability: Because the mixer settler has a large volume and a large amount of liquid, it can adapt to a certain range of material and liquid fluctuations. After adjusting the balance, the operation is relatively stable and the adaptability is strong;
• Reliable scale-up: Single-stage extraction rate and other design parameters are still relatively reliable after scale up.

FAQS

1.What is a mixer settler?

A mixer settler is a liquid-liquid extraction device used for mixing two immiscible liquids and separating them into different phases. It is widely used in solvent extraction, hydrometallurgy, rare earth separation, and chemical processing industries.

2. What materials are available for mixer settlers?

Common materials include:

• PP (Polypropylene)
• PVC
• PTFE
• Stainless Steel 304/316L
• Glass

Material selection depends on chemical corrosion resistance and process requirements.

3.What is the difference between a mixer settler and a centrifugal extractor?

Mixer settlers use gravity for phase separation, while centrifugal extractors use centrifugal force for rapid separation. Centrifugal extractors are faster and more compact, while mixer settlers are simpler and suitable for laboratory and pilot-scale testing.

4. Can the mixer settler be customized?

Yes. The mixer settler can be customized according to:

• Stage number
• cell volume
• Material
• Flow capacity
• Agitator type
• volume of mixer and settler 
• removable frame

5.What is counter-current extraction?

Counter-current extraction means the aqueous phase and organic phase flow in opposite directions through multiple stages, improving extraction efficiency and solvent utilization.
