Rycote Stereo Cyclone
The Cyclone sets a new benchmark — I am genuinely very impressed indeed. Prices range from $699 to $749, according to the chosen configuration. Rycote's innovative Cyclone wind shielding device has been joined by a range of Stereo Cyclones. We test the MS4 kit with a Mid‑Sides stereo array of Sennheiser MKH30/40 microphones.

Dense Media Separation (DMS) Plants
Dense Media Separation. A heavy medium is a heavy-fluid or heavy suspension fluid with a density greater than that of water (1g/cm3). The process of separating ore particles in heavy media is called Dense Media Separation / Heavy Media Separation (DMS / HMS). The heavy medium separation method is an advanced gravity beneficiation method.

DMS cyclone product purity relative to particle size The Ecart Probable (Ep) is a standard measure of the quality of DMS separations. The Ep represents half the difference in densities where there are 25% and 75% probabilities of particles those densities reporting to a low or high-density product fraction.

Cyclone geometry and materials of construction
The DMS cyclone is a device that is separating ore particles on both a size/shape and density basis and at the same time separating the particles that make up the medium. There are numerous interactions that take place, and these are influenced by the cyclone geometry. Figure 1. The complex inter-relationship between the variables
Cyclone Yasi, QLD 2011 | Australian Disasters
Cyclone Yasi developed as a tropical low north-west of Fiji on 29 January 2011. On 30 January, it was named Yasi by the Fiji Meteorological Service. On 2 February, it was upgraded to a Category 5 system and made landfall near Mission Beach (138 kilometres south of Cairns) between midnight and 1:00am (AEST) early on Thursday 3 February. It …
DMS cyclone modelling at De Beers
DMS cyclone modelling at De Beers. it appears that the model is behaving correctly. The next step for this work is to turn the model into a two-dimensional representation. The work of Lyman et al. (2002) shows that the increased density at the air core is localised lower in the cone around the spigot.

DMS Conical Cyclones VS Cylindrical Dense Media Separator
The motion approaches that of a forced vortex (w= k r) on the medium inlet side for a large part of the cylindrical cyclone. Although the occurrence of Rankine's vortex has been known for a long time for the conical cyclone, the flow patterns shown in Figure 4 were only partially described in early studies for the cylindrical vessels.
