P Particle Size Distribution Mining

x of a size distribution p(x) is defined in accord with the statistical variance of a continuous mathematical distribution. ˙2 x = Z 1 0 p(x)(x x )2 dx (15) The variance measures the mean squared-deviation of the distribution from its mean value. The units of ˙2 x are [m 2]. Because ˙ x is a complicated function for standard aerosol and ...

    The particle size distribution can be described with the help of a power law or Pareto distribution. Comparing the measured particle size distribution with the Pareto distribution shows that particles with a diameter 7 microm are under-represented. As the particle size distribution is dependent on the flow velocity, so is the value of the ...

    Particle Size Distribution Functions

    Since it is often not possible to obtain particle size data from d p = 0 to d p = ∞ , it is desirable to use a function with a minimum number of free parameters to describe the particle size distribution. From such a function all moments can be calculated. If the function has 3 free parameters, for example, such as the mean, standard ...

    When reporting a particle size distribution the most common format used even for image analysis systems is equivalent spherical diameter on the x axis and percent on the y axis. It isonly for elongated or fibrous particlesthat the x axis is typically displayed as length rather than equivalent spherical diameter.
