How do centrifuges work? - Explain that Stuff

Sep 17, 2017 . A centrifuge is simply a machine that spins around to make a large and useful force. Small centrifuges are used in scientific laboratories (for example, to separate blood products). You can find much bigger ones in aerospace-labs, where they're used for testing astronauts, pilots, and their equipment to.

Gravity Separation

An example of a centrifugal jig is the Kelsey jig, manufactured by Mineral Technologies. This incorporates the pulsing action, water injection and the use of a ragging medium and internal screen of a conventional jig, but in addition centrifugal spinning motion to enhance the gravity separation. This enables sand sized.
