### Centrifugal Separation - an overview ScienceDirect Topics

A vessel with a diameter of 25.4 cm spinning at 1700 rev/min gives an acceleration at the centrifuge wall of some 400 g. In terms of settling this means that centrifuging a crude oil for 30 s is at least equivalent to simple gravitational settling over a 24 h period.

### Centrifuge - an overview ScienceDirect Topics

Basket centrifuges are useful for separating mould mycelia or crystalline compounds. The centrifuge is most commonly used with a perforated bowl lined with a filter bag of nylon, cotton, etc. (Fig. 10.15). A continuous feed is used, and when the basket is filled with the filter cake, it is possible to wash the cake before removing it.

### CHAPTER 3 CENTRIFUGATION 3.1 INTRODUCTION

cake surface from the rotational axis of a centrifuge, respectively. From Equations [1] and [2], one can see that the rate of filtration should increase with ω and the thickness (rS-r0) of the water over a filter cake. According to the Equation [3], ∆P becomes zero when the water over the cake disappears, i.e., r0=rS.
