Solids and liquids working principle -2

2 Centrifuge Separation

The indissoluble liquids and solids with different densities will be separated while they are rotated at a high speed in the bowl, where the particles with heavier density move to the inside wall of bowl body, the lighter liquid toward the center of the bowl. Because the centrifugal force generated in the centrifuge fields in much larger than the gravity force, it takes only very short time for the centrifuge separation to achieve the same separation efficiency in the gravity fields. Especially when the gravity separation can not be available, the best method is used with centrifuge separation.

 

3 Separation space

There is a stack of discs installed in the bowl, which divide the bowl space into many conical cavities. That can shorten the sedimentation distance and improve the separation efficiency.

The moving trace of the limit particle “A” occurs between the discs (conical cavity).

Liquids and solids working princle -1

The liquids and solids, which are interactive indissoluble and with different densities, will be separated and sediment in the centrifuge and gravity force fields.

The separations that occur in the gravity field are called gravity separation and sedimentation; in the centrifuge field called centrifugal separation and sedimentation.

 

  1. 1.      Gravity separation   

The indissoluble liquids and solids with different densities will be separated and sediment slowly by the gravity in the gravitational fields. The solid particles freely settle down to the bottom because of heavier gravity and the lighter liquid float up, so the separation and sedimentation take place. This gravity separation and sedimentation need a very long time and cover a large area.
