Understanding Cyclone Dust Collectors | Fluid Engineering Blog
Thus, to have any validity in predicting cyclone performance, the data must define the dust's aerodynamic properties. All information must be representative of the airborne particles entering the cyclone's inlet. Density and size distribution are best determined by measuring terminal or settling velocities in still air.

et al., 2014]. Size distribution not only defines the emission and deposition fields for dust particles but also their lifetime and interactions with radiation, clouds, and water. Huneeus et al. [2011] showed that, because of the differences in the representation of the particle size distribution, the dust mass extinction efficiency

The P80 separation is the particle size for which 80% of the cyclone overflow is finer than that size. For example, if a sample of cyclone overflow was passed through a bank of screens and 80% of the sample was found to pass through (finer than) the 75µm screen then the P80 point for the overflow is 75µm. Cyclone Operating Pressure
An Analysis of Mass Balance and Fractional Particle Size ...
In this study, a complete mass balance of magnetite and coal in the various parts of a densemedium cyclone (DMC) circuit was determined and fractional size distributions of magnetite and coal were analyzed for the circuit. The DMC overflow product contained % of the feed coal, whereas % of the feed magnetite reported to the DMC underflow.

Comparison of the Performance of MRdeDuster with Other ...
comparative study was done to investigate the performance of MRdeDuster with other conventional cyclones in terms of collection efficiency and pressure drop. The performance of MRdeDuster was measured by its collection efficiency based on the particle size distribution of activated carbon.
Troubleshooting Cyclone Dust Collectors

Efficiency. The separation yield of a cyclone is 99% at 50 µm. This is considerably higher than that of sedimentation chambers or impact separators. A guideline figure is: 90% yield for 10 µm particles. Cyclones are most efficient at high air speeds, small cyclone diameters and large cylinder lengths (pencil cyclones).

a twostage, threeproduct heavy–medium cyclone that consisted of a primary cylindrical cyclone and a secondary cylindrical/conical cyclone. Three products can be obtained in a single separation step. In the primary cylindrical cyclone, particles were mainly classified by size so that highash fine coal can be discharged through the overflow.

Introduction to Fluidization AIChE
Indeed, most particles used in fluidized beds are Group A powders, mainly because they can be easily made by spray drying. Group A particle sizes range from 30 μm to 125 μm, and particle densities are on the order of 1,500 kg/m3. Typically, Group A powders .
