Tube centrifuges are suitable for all kinds of suspensions that are difficult to separate. They are extremely suitable for solid-liquid separation with small concentration, high viscosity, fine solid particles small solid-liquid gravity. At present, tubular centrifuges are mainly used for the separation of non-homogeneous liquids in food, chemistry, microorganisms other industrial sectors. It is called a drum, which is basically driven by an electric motor. After the suspension ( emulsion) is added to the drum, it is rapidly driven to rotate at the same speed as the drum, the components are separated discharged respectively under the centrifugal force. Generally, the higher the rotating speed of the drum, the better the separation effect.
For particles less than a few microns, such as proteins, which are colloidal semi colloidal in solution, the sedimentation process cannot be observed by gravity alone. The smaller the particles are, the slower the sedimentation is, the more serious the diffusion phenomenon is. Therefore, it is necessary to make use of the strong centrifugal force generated by the tubular centrifuge, so that the centrifuge can force the particles to overcome the diffusion produce the sedimentation movement.
Tube centrifuge tube centrifuge has been used for a long time to separate the solid particles in the suspension the liquid; to separate the two kinds of liquid with different densities in the emulsion, which are insoluble in each other (like separating cream milk); it can also be used to remove the liquid in the wet solid.
