Available in PDF, EPUB and Kindle. Book excerpt: Abstract In this study a complete solution methodology is developed for the simulation of hydrocyclones. A commercial software package, Ansys 12 Fluid Dynamics (Fluent), is used to solve the governing conservation equations. Turbulence is modelled using the large eddy simulation, and the discrete particle model is used to predict the particle separation. Two hydrocyclones of different geometries were studied, and the simulation results are compared with the experimental values. There are two key factors for obtaining a reliable result. The first is the domain discretization, and the second is the generation of a consistent initial value, including the establishment of a stable air core. Using the methodology developed, superior agreement is obtained between the predicted and experimental values of pressure, velocity distribution, air core profile and separation efficiency. The developed and validated model is used to investigate the hydrocyclone performance for separation of light and heavy particles in slurry. The effect of overflow pressure, feed flow rate, particle size, vortex finder length, particle concentration and vortex finder diameter were investigated. The prediction of air core profiles demonstrated the accuracy of the simulation. In terms of design variables increasing the vortex finder length is shown to result in an increase in the recovery of light particles in the overflow. In the case of operating variables, the recovery of light particles in the overflow improved by increasing the size of light particles, feed flow rate and decreasing feed solid concentration. The ratio of the vortex finder diameter to the apex diameter was found to be the most important design factor on the hydrocyclone performance.

Available in PDF, EPUB and Kindle. Book excerpt: It is with great pleasure and satisfaction that we introduce this volume which comprises the papers accepted for the 4th International Conference on Hydrocyclones held in Southampton from 23rd to 25th September 1992. As the name implies, this is the fourth Conference in the series, with the previous ones held in Cambridge in 1980, Bath in 1984 and Oxford in 1987. The papers cover a wide span of activities, from fundamental research to advances in industrial practice and, as in the earlier volumes, make a significant contribution of lasting value to the technical literature on hydrocyclones. Hydrocyclones continue to widen their appeal to engineers; besides their traditional role in mineral processing they now attract a lot of attention in chemical engineering, the oil and gas industry, power generation, the food industry, textiles, metal working, waste water treatment, pharmaceuticals, biotechnology and other industries. The reason for this continuously increasing attention is, as David Parkinson (General Manager of Conoco (UK)) said recently, that" ... a hydrocyclone is an engineering dream, a machine with no moving parts." Yet as this Volume clearly shows, the hydrocyclone can do so many things and do them well, whether the application is in solid-liquid, liquid-liquid or liquid-gas separation.

Categories of cyclone; commercially available cyclone equipment; and the specific industrial applications of the hydrocyclone are also surveyed. The text will be of practical use to industrial engineers, mechanical engineers, plant operators, miners, and researchers.
Book Synopsis Gas Cyclones and Swirl Tubes by : Alex C. Hoffmann
Download or read book Gas Cyclones and Swirl Tubes written by Alex C. Hoffmann and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has been conceived to provide guidance on the theory and design of cyclone systems. Forthose new to the topic, a cyclone is, in its most basic form, a stationary mechanical device that utilizes centrifugal force to separate solid or liquid particles from a carrier gas. Gas enters near the top via a tangential or vaned inlet, which gives rise to an axially descending spiral of gas and a centrifugal force field that causes the incoming particles to concentrate along, and spiral down, the inner walls of the separator. The thus-segregated particulate phase is allowed to exit out an underflow pipe while the gas phase constricts, and - in most separators - reverses its axial direction of flow and exits out a separate overflow pipe. Cyclones are applied in both heavy and light industrial applications and may be designed as either classifiers or separators. Their applications are as plentiful as they are varied. Examples include their use in the separation or classification of powder coatings, plastic fines, sawdust, wood chips, sand, sintered/powdered meta!, plastic and meta! pellets, rock and mineral cmshings, carbon fines, grain products, pulverized coal, chalk, coal and coal ash, catalyst and petroleum coke fines, mist entrained off of various processing units and liquid components from scmbbing and drilling operations. They have even been applied to separate foam into its component gas and liquid phases in recent years.

Book Synopsis Physical Separation and Enrichment by : Saeed Farrokhpay
Download or read book Physical Separation and Enrichment written by Saeed Farrokhpay and published by MDPI. This book was released on 2020-04-01 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book includes 12 papers from around the world on topics related to physical separation and enrichment in mineral processing. Physical separation is commonly used in the mineral industry to separate valuable minerals from gangues using differences in their physical properties. Physical separation methods have several advantages over other mineral processing techniques due to their high efficiency, low capital and operating costs, no additional chemicals required, and consequently, lower environmental hazard. They can be applied to the ores from mines or tailinsg, or in the recycling stage for scavenging the desired elements.
