Centrifuges disk type

One variation of the disk-type bowl centrifuge is the nozzle centrifuge, so named because nozzles are arranged on the periphery or on the bottom of the bowl in a... 

Very fine dispersions can be separated effectively with disk-type centrifuges. Commercial units have capacities of 5-500 gpm and are capable of removing water from hydrocarbons down to the ppm range. A mild centrifugal action is achieved in hydrocyclones. They have been studied for liquid-liquid separation by Sheng, Welker, and Sliepcevich (1974), but their effectiveness was found only modest. The use of hydrocyclones primarily for the recovery of solid particles from liquids is described in the book of Bradley (1965). A symposium on coalescence has papers by Belk (1965), Jordan (1965), Landis (1965), and Waterman (1965). 

A separator centrifuge is a disk-type, continuous centrifuge. The starch is concentrated in the separator due to centrifugal force. Starch granules with the highest density... 

CPC = coil planet centrifuge ACPC = type-I L-angle rotor CPC DCCC = droplet CCC HCPC = horizontal flow-through CPC MLCPC = type-J multilayer CPC SDA = spiral disk assembly TCC = toroidal coil centrifuge ICPC = type-I CPC XCPC = cross-axis CPC. 

Centrifugal partition chromatography (CPC), a type of CCC that uses discrete partition cells inside a rotor, was used by Renault et al. (1997) to separate anthocyanins from black currant and grape skins. They used two instmments from Sanki Engineering Ltd (Kyoto, Japan) a laboratory model LLB-M and a pilot-scale model LLI-7, both fitted with a stacked disks type rotor. 

These concepts are used to analyze separations in the botde centrifuge, the imperforate bowl centrifuge, and the disk centrifuge. Separation by density difference in other types of centrifuges can be analyzed by analogy. 

ScroU centrifuges discharge soHds continuously and usuaUy drier than disk and imperforate batch types. GeneraUy disk centrifuges have the highest values of Z or for a given size and therefore the best abUity to coUect fine particles at a high rate. 

The first three types, including the manual-discharge disk, are batch-feed centrifuges, whereas the latter three, including the intermittent and nozzle-discharge disks, are continuous centrifuges.
