Centrifuge Rotors. Rotors in centrifuges are the motor devices that house the tubes with the samples. Centrifuge rotors are designed to generate rotation speed that can bring about the separation of components in a sample. There are three main types of rotors used in a centrifuge, which are: 1. Fixed angle rotors. Figure: Fixed angle rotors.
1) Feeding: The slurry is introduced to the rotating solid bowl. Centrifugal force drives the solids to the bowl wall. 2) Spinning: The mother liquor is clarified and the solids are sedimented and compacted. 3) Liquid Discharge: The clarified mother liquor is discharged by either overflowing the bowl rim and / or with a tangential liquid skimmer. If there are …
