Separation Principle

1. 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 suspends to the upper surface. A rather distinctive dividing plane forms between the light phase and heavy phase. The separation speed is affected by the difference of density between the light phase and heavy phase that make up the mixed liquid. The larger the difference in density is, the faster the separation speed will be.

2. 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.
