The distribution of particle sizes

Journal of the Franklin Institute, 1950
Abstract In this paper the older literature on distribution of particle sizes is reviewed critically. The distribution law should be connected with the law of growth of crystals, for which is chosen the exponential law as Galton indicated long ago in an analogous case. The law which then follows is the so-called Logarithmico-Normal law.

Particle Size and Distribution

2018
Particle size distribution, the measure of subdivision of a solid, can be directly correlated with uniformity of quality and performance. Primary particle size is a physicochemical property that may impact temporal chemical and physical effects such as stability and aggregation.

Particle Size Distribution

2017
In this chapter, a state of the art of Particle Size Distribution (PSD) measurement of bio-based aggregates and characterization methods is presented. Shiv particles coming from the stem of plants cultivated either for their fibers (hemp, flax, etc.) or for their seeds (oleaginous flax, sunflower, etc.) are very different from the mineral aggregates ...

Estimating Functionals of Particle Size Distributions

Biometrika, 1971
SUMMARY Data consisting of the intersections of a planar or linear probe with a field of spheres, with a diameter distribution G(x), is often used to estimate linear functionals or their ratios. It is shown that distribution-free estimators may be poor and that their distribution, even in large samples, depends on knowledge of G for small x that may be

On Particle‐Size Distributions in Soils

Soil Science Society of America Journal, 1993
Abstract Measurements of soil particle‐size distributions have been performed down to 20‐nm radius using, beside classical methods such as sieving and sedimentation, mainly static and dynamic light scattering. The number of particles N per unit volume with a radius larger ...

A study of particle size distributions

Powder Technology, 1990
Abstract The properties of a size distribution of particulate materials are systematically discussed. In order to avoid possible conceptual problems and difficulty in dealing with a distribution, some boundary conditions are given, based on which the limitations of the distribution functions in the literature are discussed.

Particle size distribution by design

Chemical Engineering Science, 2001
Publisher Summary This chapter presents a strategy for designing solids processes to produce particles with a desired size distribution. Heuristics and generic flowsheet structures are used to guide decision making. Computer simulations based on discretized population equations along with suitable solids processing models are used to meet the ...

PARTICLE‐SIZE DISTRIBUTION OF GLAZES*

Journal of the American Ceramic Society, 1941
A bstract The particle‐size distributions of experimental and commercial stains and glazes and glaze materials were determined by using the Andreasen pipette method. The variation in particle size of two porcelain glazes, raw and fritted, was correlated with the glaze working

Distribution of Particle Size in Dust

Nature, 1964
DAVIES1 says that when the power law is used in the form: where N is the number of particles below diameter D, then K is not just an arbitrary concentration factor. He then states that the smallest particle size (Ds) is a function of K, a statement that appears to me to be just ...
