This series copy the technique of Alfa Laval NX 418 series, have the same structure, principle and application.
The machine could deal with the material which range of concentration is large, small size which widely distributing. Solid particles are less 0.5mm as rigid particles, and less than 10mm as non-rigid particles, the machine can be effectively treated.

Separtion Principle

Taking advantage of the principle that the light liquid, heavy liquid and solid phase, with different density and mutually insoluble in the mixed liquid, gain different sedimentation speed in the centrifugal force field or gravity force field, separating stratification or causing the solid particles in the liquid to deposit can be achieved.

In the gravity force field or centrifugal force field, the light liquid phase, the heavy liquid phase and the solid phase with different density and mutually insoluble in the mixed liquid, respectively gain different sedimentation speed, and thus separate and stratify. In the gravity force field it is called gravity separation, while in the centrifugal force field it is called centrifugal separation.

Gravity Separation

On account of difference in density, the mixed liquid in the container, after a period of time, is gradually divided into 2 layers. The heavy phase particle of the mixed liquid deposits to the bottom of the container, while the light phase one suspends to the upper surface. A rather distinctive dividing plane forms between the light and heavy phases. The separation speed is affected by the difference in density between the light and heavy phases that make up the mixed liquid. The larger the difference in density is, the faster the separation speed will be.

Applications

1. Liquid clarification: to remove the solid particles in suspension to get clarify liquid
2. Solid phase dehydration: dealing with the solid particles to reach dehydration material.
3. Particle size classification: to remove solid particle of large size in material.
