Properly designed cyclones can remove nearly every particle in the 20- to 30-µm range. Typical cyclone separators have efficiencies of 70–90%. Gas inlet velocities should be in the range of 100 to 150 ft/s, but may be limited by re-entrainment of dust particles or by unacceptable pressure drop. At the tapered end of the chamber, where …
separation processes. Cyclones can be divided based on their mode of operation into hydrocyclones, dense medium cyclones, and water-only cyclones (Fig. 1). These cyclones are usually fixed vertically such as hydrocyclones and water-only cyclones, or inclined with 10-15o from horizontal such as a dense-medium cyclone.
General Information. In general, cyclones use centrifugal force to separate particles in a gas or liquid stream. In hydrocyclones, the liquid is the fluid medium. There are two design classifications for cyclones. …

This chapter describes the principles behind these commonly used numerical modeling tools; Though these tools have been widely used in many mineral-processing areas, this chapter mainly gives an overview of their application in mixing, classification, grinding, and heavy media separation. 7.2. Discrete Element Modeling (DEM)
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 …
The hydrocyclone operation consist of having the ore slurry pumped into its feed inlet, the ore is then separated by size with the fine material coming out of what is referred to as the "OVERFLOW" via a Vortex Finder. The mineral that still requires grinding is named the "UNDERFLOW" via the Apex Finder. These two ….
As discussed in the introduction, such a heuristic has been tested widely in the mineral processing research, but except for the work of Mainza et al. (2004), the classification principle was not modified significantly. It was also found that replacing cyclones with screens reduced circulating loads, lead to increased throughput, and …
The Principle of Operation of Hydrocyclone is, in simple terms, the forces of gravity and centrifuge to separate large or heavy particles from smaller and lighter one. When sized correctly will "cut" like the 'real cyclone' below VS the imaginary 'ideal' one on the left. Hydrocyclones are preferred units for sizing or desliming large ...
Dense medium cyclone inlets can have two basic forms i.e. square and rectangular. In both cases, the area of the opening is the same and equivalent to a circle with a diameter of 20% of the cyclone diameter. The top size for a square opening will always be greater than that of a rectangular opening.

Classifying cyclones are the most commonly used technology for achieving particle size separations below 300 microns. Classifying cyclones are comprised of a cylindrical …
The use of the heavy media cyclone (HMC) Separation process for the treatment of ores in a particular size range is comparatively new to Australia. The paper describes briefly the principles of HMC operation. Reference is made to early development work, the pilot plant trials and the acceptance of the technique as a mineral dressing process. The Mitchell …

A hydrocyclone fulfills two important functions: separating fine from coarse particles and producing an underflow slurry of a consistency that induces efficient grinding in the mill to which the slurry is recycled. Generally, the …
A small diameter has, however, a low fluid capacity and in most cases such cyclones have to be manifolded and connected in parallel to be of industrial use. Applications of the hydrocyclone were originally in …
An axial inlet cyclone was developed and tested for wet size classification of particulate materials with the purpose of providing an alternative to the tangential inlet cyclone used traditionally in the mineral processing industry.
