Cyclone Separator. The cyclone separator is an important piece of equipment in air pollution control systems. This is referred to as a centrifugal separator or an initial separator device. Cyclone separator is Patented in 1885 by an American John M. Finch. He made for his company a knickerbocker for dust collecting.

Cyclone separators work much like a centrifuge, but with a continuous feed of dirty air. In a cyclone separator, dirty flue gas is fed into a chamber. The inside of the chamber creates a spiral vortex, similar to a tornado. This spiral formation and the separation is shown in Figure 2.

Particle separation in cyclones can vary considerably depending on such factors as feed head, mud weight, percent solids, and properties of the liquid phase of the mud.Generally speaking, increasing any of these factors will shift the cut point curve to the right, increasing the size of solids actually separated by the cyclone..

Cut Size (d50) The cut size (or d50) is the particle size at which there is equal chance that the particle will report to the overflow or underflow. For example, if D50 = 74 μm, then 50% of the particles in the sample are larger than 74 μm, and 50% smaller than 74 μm. D50 is usually used to represent the particle size of group of particles.

In cyclone separator, the centrifugal force is used to separate solids from fluids. The separation depends not only on the particle size but also on density of particles. Hence depending on the fluid velocity, the cyclone separator can be used to separate all types of particles or to remove only coarse particles and allow fine particles to be ...

The separation (grade) efficiency of cyclones represents the variation of the separation efficiency with the particle size. The particle size recovered at an efficiency of 50% is called the cut-size or d 50. For estimating the cut-size, two different approaches are found in the literature . In the first approach, the cut size is reported in μm.
