Large Capacity Decanter Centrifuges Horizontal Continuous Separation Centrifuge

Description

The continuous separation centrifuge 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.

Separation 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.

Centrifugal separation

When the container filled with mixed liquid rotates at high speed around its own axis, due to the difference in density between the two phases making up the mixed liquid, they bear different centrifugal force. Under the action of a larger centrifugal force, the heavy phase in the mixed liquid quickly subsides on the inner wall of the drum, while the light phase slowly adhere close to the surface of heavy phase. The faster the container rotates, the larger the difference in centrifugal force borne by the light and heavy phases that make up the mixed liquid, and the faster the separation speed. When the container is equipped with such parts as feeding mainly comprised of such parts as drum, helical propeller, planet gear differential mechanism, pedestal, hood and lubricating system.
