What is Centrifugal?

10/31/2013 4:09:44 PM | by Anonymous


The first continuous centrifugal separator in making its commercial application feasible is the English military engineer Benjamin Robins whom invented a whirling arm apparatus to determine drag. A drag is in fluid dynamics that refers to forces which act on a solid object in the direction of the relative fluid flow velocity. In 1864, the first dairy centrifugal is invented by Antonin Prandtl and it is to separate the cream from the milk. This is to separate the particle and liquid during the filtration process.


A centrifugal is a machine that is used for particle or fluid separation. Centrifugal is a piece of equipment that is generally driven by an electric motor or some older models were spun by hand that puts an object in rotation around a fixed axis by applying a force of perpendicular to the axis.


A centrifugal is also used to separate the components of blood in the blood banks. This usually works by using the sedimentation principle where the centripetal acceleration causes denser substances to separate out along the radial direction from the bottom of the tube and this will tend to move to the top of the tube in the rotating picture to move it to the centre.


The filtering centrifuges use the centrifugal force to pass liquid through a filtration media such as a cloth or screen while solids are captured by the filtering media. Sedimentation centrifuges use the force to separate solids from liquids as well as use the two liquids from different specific properties.


Some sedimentation types include disk-track, decanter, solid bowl basket and tubular bowl centrifuges. These machines rely on the use of centrifugal force by generating several hundreds or thousands of times earth’s gravity. They are used for separating solids from liquids, liquid-solid and liquid-liquid separation.


However, centrifuges do not mass produced like motors, pumps, cars or refrigerators therefore the cost associated with this purchase of centrifuges for sale are normally higher when compared to other types of process equipment. It is estimated that there are close to two hundred specific applications industrial centrifuges that are for used. They are not a “one size fits all” type of machines and all these industrial centrifugal are manufactured for a specific application to be used in.


The process of the centrifugal is one of the most important and wide applied research techniques in the cellular, bio chemistry and molecular biology as well as in machine. The current research and clinical applications rely on isolation of cells, macromolecules and sub-cellular organelles that are often in high yields.


These machines use g-force to isolate suspended particles from their surrounding medium on either a batch or a continuous flow basis. There are many applications and some may include sedimentation of viruses and cells therefore a separation of sub-cellular organelles and isolation of macromolecules such as proteins, DNA or RNA is needed.


If there is a special purpose of the centrifugal, the centrifuges can be designed as per the customer’s unique industrial applications. These industrial centrifuges are widely used in all type of industries to separate solid from liquid. The benefit of using these centrifuges is that they make it possible yet easily with the help of the centrifugal force.
