Functions of Centrifuge:

A device which is used to separate the various materials by the rotation at high-speeds around a central axis is called Centrifuges. The Centrifuge and the Functions of Centrifuge is very important matter to study for complete information about this device.
The materials which you want to be separated is held. It is designed to grip numerous flasks which are holding the materials you want to be separated.

A centrifuge is used to separate particles or macro-molecules:
  • Cells
  • Nucleic acids
  • Proteins
  • Sub-cellular components

Basis of separation:

  • Density
  • Shape
  • Size

Functions:

Commonly it is used to separate the different solids, or liquids held within the liquid. The main functions of Centrifuge are given below:

Separation (solid/liquid, solid/liquid/liquid and solid/solid/liquid separation):

As we know that the solids are heavier than the liquid so this process is used to separate the solid from the liquid. By this process we can separate two different kinds of Phases from each other, but in this case one of the phases should be lighter than the other one. In between the solid and the liquid separation can be done by initiation of the dispersed solid phase because as we know that at the most of the time solids can be lighter than liquid.

Clarification- minimal solids in liquid product:

A centrifuge is also used for the clarification, in this process the lighter liquid phase, which is separated is discharged by the machine. In the light continuous phase, they minimize the separate suspended objects.

Classification -sort by size and density:

We can classify the different size of solids through the process. We also can use it to classify the crystals of different size range. Sometimes in its result of the disconnected solids can be the product.

Degritting- remove oversized and foreign particles:

Classification and Degritting have the same meaning, so here in this process the particles which are not needed or larger in size can be rejected in the heavier phase, and valuable lighter solids are settled with the lighter liquid phase.

Thickening or concentration- remove liquid, concentrate solids:

By using sedimentation and compaction, we can remove the excess liquid phase in the overflow or contract to concentrate on the solid phase. In downstream processing the volume of the product can be reduced.

Separation and repulping - remove impurities by washing or diluting:

For removing the expended wash liquid with liquefied contaminants or fine suspended solids the suspension can be sanded out.
