Modeling the Multiphase Flow in a Dense Medium Cyclone
Industrial & Engineering Chemistry Research, 2009A mathematical model is proposed to describe the multiphase flow in a dense-medium cyclone (DMC). In this model, the volume of fluid multiphase model is first used to determine the shape and position of the air core, and then the mixture multiphase model is employed to describe the flow of the dense medium (comprising finely ground magnetite in water ...

Development and Evaluation of the CAVEX Dense Medium Cyclone
International Journal of Coal Preparation and Utilization, 2010The CAVEX dense medium cyclone (DMC) was developed in the later part of the 1990s as a result of the expertise developed by Weir engineers in slurry pumping. The inlet area of the cyclone is designed to minimize turbulence and to reduce wear at the feed entry point, which provides more energy for particle separation at a given feed pressure.

Modelling of dense-medium cyclones treating coal
International Journal of Mineral Processing, 1986Abstract Experiments have been conducted on a 75-mm dense-medium cyclone treating coal in the size range −2.0 + 0.5 mm using magnetite as the medium under different design and operating conditions. The design variables studied were vortex finder diameter and spigot diameter and the operating variable was the specific gravity of the feed medium.

A study of coal washing dense medium cyclones
2023Dense medium cyclones are widely used separating devices for the washing of plus 0.5mm coal. As approximately fifty percent of Australian coal is washed in these devices, efficient cyclone operation is obviously important. Optimization of dense medium cyclone circuits requires an appreciation and understanding of both cyclone operation and common ...

Numerical studies of the effects of medium properties in dense medium cyclone operations
Minerals Engineering, 2009A mathematical approach is proposed to describe the multiphase flow in a 1000 mm industrial dense medium cyclone. A mixture multiphase model is employed to describe the flow of the dense medium (comprising finely ground magnetite contaminated with non-magnetic material in water) and the air core, where the turbulence is described by the well ...

OPTIMAL UTILIZATION OF DENSE MEDIUM CYCLONES
2016In the current world mining climate the focus is on reducing cost and increase productivity. In many instances this productivity is associated with increased tonnages, “sweating the assets”, which in many instances result in equipment being pushed to above their design limits. Simultaneously cost are being reduced, costs like spares holding, consumable

The monitoring of medium rheology in dense medium cyclone plants
1989Dense medium cyclone theory, supported by extensive experimental and plant-scale evidence, demonstrates that medium rheology (stability and viscosity) substantially affects cyclone performance in mineral applications.Two instruments have therefore been developed to allow medium stability and viscosity to be-monitored in the plant environment.
