Some problems of hydrocyclone

open access: yesFLOTATION, 1968
Considering the outstanding merits of the hydrocyclone, it seems natural that it should likely replace the mechanical classifier in a closed grinding circuit.In this paper discussions were made about several problems in applying the hydrocyclone into practice.

hydrocyclone Performance Comparison between Recycled Single Stage and Double Stage Hydrocyclones

open access: yesIraqi Journal of Chemical and Petroleum Engineering, 2020
This research presents a comparison of performance between recycled single stage and double stage hydrocyclones in separating water from water/kerosene emulsion. The comparison included several factors such as: inlet flow rate (3,5,7,9, and 11 L/min), water feed concentration (5% and 15% by volume), and split ratio (0.1 and 0.9).

Study on gas–liquid two-phase flow and flow restriction and closure characteristics of hydrocyclone valve

open access: yesAIP Advances
Taking the hydrocyclone valve as the research object, the optimal physical model of the hydrocyclone valve is determined from the “S-type” flow restriction and closure.

Study of a static screen, jig, spiral, and a compound water cyclone in a placer gold recovery plant [PDF]

open access: yes, 1987
During the 1986 mining season both laboratory and field test work were conducted to study the performance efficiencies of a wedge-wire static screen, a Pan-American jig, a Reichert Mark VII spiral, and a 12" compound water cyclone.

Mathematical simulation of hydrocyclones

open access: yesApplied Mathematical Modelling, 1987
Abstract Cyclones are used widely in industry as classifying devices. Due to the complexity of the multiphase flow field in such a device, prediction methods are at best semiempirical and geared towards predicting overall performance parameters. This article presents a real alternative, using state-of-the-art numerical techniques to address the ...

Study on Flow Field Distribution and Separation Efficiency of Guide-vane Hydrocyclone

open access: yesShiyou jixie, 2018
To study the phenomena of oil droplets agglomeration and breakage in the flow field, CFD technology was used to numerically simulate the guide-vane type liquid-liquid hydrocyclone applied in the oilfield.

Liquid-liquid extraction intensification by micro-droplet rotation in a hydrocyclone

open access: yesScientific Reports, 2017
The previous literature reports that using a hydrocyclone as an extractor intensifies the mass transfer and largely reduces the consumption of extractant from 1800–2000 kg h−1 to 30–90 kg h−1.
