What Are Industrial Centrifuges
To fully understand an industrial centrifuge, what it is and its uses, let’s start by remembering some physics. A centrifuge uses centrifugal force to separate various components in a liquid depending on their densities. Did you know one of the first functioning centrifuges separated the cream from milk?
The process includes spinning the fluid at high speeds in a machine. The speed creates a centripetal force inwards and the relative centrifugal force outwards—where it applies a pressure many times the force of gravity.
The two forces involved in a centrifuge, the centripetal force and the relative centrifugal force, are described by research physicist Andrew Ganse as, “The centripetal force and centrifugal force are really the exact same force, just in opposite directions because they’re experienced from different frames of reference.”
Following the principles of sedimentation, Stokes law, the less dense components in the fluid being processed ‘float’ away to the centre due to the pressure. At the same time, denser elements sink to the bottom.
What Industry are Industrial CentrifugesUsed In?
There are many industries that these huge machines can be found in. We have listed the industries below.
An Industrial Centrifuge In Action
The creation of products is central to the companies listed above. In creating essential products for human consumption, there is a demand for purity in the components used. A purity, only achieved by breaking a substance down to its basic constituents—precisely what an industrial centrifuge does.
Depending on the industry, the centrifuges are much larger than you will find in a science lab. The industrial centrifuges rotate at a high RPM—revolutions per minute—producing the inward centripetal force and the centrifugal force outwards, which produces the separation of the components within minutes.
There are several uses for an industrial centrifuge, and these are the separation of,
- Solids from liquids
- Liquid-liquid separation
- Liquid-liquid-solid separation
Sedimentation & Filter Industrial Centrifuges
Used predominantly in the pharmaceutical industry, this type of centrifuges help produce and analyse drugs. In this process, the higher density particles are forced to the outer edge of the container, creating a dense pellet. Different types of sedimentation centrifuges can be employed when you want the separation of two liquids with different specific gravities and solids from liquids.
Types of Sedimentation Centrifuges
- Tubular bowl
These industrial centrifuges have filters placed to catch particles as they are pushed outward by centrifugal force. Several filters are used in the different filter centrifuges, depending on the job.
Types of Filter Centrifuges & Their Filters
- Peeler centrifuge uses a filter cloth
- The inverting centrifuge uses a filter cloth
- The pendulum centrifuge uses a filter cloth
- Worm screen centrifuge uses a wire mesh
- The pusher centrifuge uses a slot screen
