Controlling characteristics of hydrocyclone via additional water injection

Abstract

The results of measuring the parameters of the classification of suspended solid particles by their sizes in a hydrocyclone equipped with a system for additional water injection are considered. The additional injection of water considerably changes the characteristics of the hydrocyclone. A mathematical model that predicts the trend in the change of hydrocyclone characteristics upon the injection of water is described. The mechanisms of the action of radial and tangential injection on classification have been explained. An efficient regime of injection is recommended to attain the required classification characteristics.

Fish hook effect in centrifugal classifiers – a further analysis

“…Both the models of Laser equipment use Mie theory for interpretation of the size analysis Similarly, it is equally logical to conjecture that the all the investigators who use Fraunhofer approximation to interpret the size analyses, are likely to observe/detect fish hook in the efficiency curves. Detection of fish hook Bhaskar et al (2007b), Ray et al (2000), Dueck et al (2012a), Kraipech et al (2002), Schmidt and Werther (2006), Margraf and Werther (2009), Schubert (2004 is in conformity with such an expectation.…”

“…• Dueck et al (2007• Dueck et al ( , 2012a too report that with increased solids concentration, fish hook depth decreases.…”

“…Split Rasio (S) : rasio aliran volume overflow ke aliran volume inlet c. Total efisiensi (E) : Rasio massa partikel dalam underflow ke inlet Hydrocyclone dengan menggunakan injektor di laboratorium, di tunjukan pada Gambar 3. Dengan penambahan injektor ini, disuntikan air untuk memberikan kecepatan radial tambahan dari dinding ke porosnya, dan produk berada dalam pipa bawah air [16].…”
