Particle Size Analysis
1.1 INTRODUCTION
In many powder handling and processing operations particle size and size
distribution play a key role in determining the bulk properties of the powder.
Describing the size distribution of the particles making up a powder is therefore
central in characterizing the powder. In many industrial applications a single
number will be required to characterize the particle size of the powder. This can
only be done accurately and easily with a mono-sized distribution of spheres or
cubes. Real particles with shapes that require more than one dimension to fully
describe them and real powders with particles in a range of sizes, mean that in
practice the identification of single number to adequately describe the size of the
particles is far from straightforward. This chapter deals with how this is done.
1.2 DESCRIBING THE SIZE OF A SINGLE PARTICLE
Regular-shaped particles can be accurately described by giving the shape and a
number of dimensions. Examples are given in Table 1.1.
The description of the shapes of irregular-shaped partic ... read full excerpt from Introduction to Particle Technology ebook
