Classification & Separation. Hosokawa's classifiers are engineered to meet industry's increasing need for finer particles and more narrow particle size distribution. Our classifiers are designed to consistently produce particle size distributions that are: uniform and homogeneous; spherical and smooth and dry and easily dispersible.

Particle Size Classification The outcome of the particle detection we covered in part 2 of this series is a sheet with the results of each detected particle. The size (typically the maximum Feret diameter) of each particle is listed.
In summary, a particle size specification is required if the particle size of the drug substance is critical to drug product performance (i.e., dissolution, solubility, bioavailability, content uniformity, stability, or product appearance) or drug product manufacturability (i.e. processability).

Particle size as an index for the classification of milled wheat products The particle size index (PSI) is a widely used measure of wheat hardness (i.e., the physical resistance of wheat kernels to a crushing or shearing force as they are milled into smaller particles or ﬂour).
Explanation: Particle size classification used only as designation of particle sizes, and do not signify the naturally occurring types which are mixtures of particle of different sizes. Sanfoundry Global Education & Learning Series – Geotechnical Engineering.
Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be applied to other granular materials. This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain.
5.1 The gradation of the soil is used for classification in accordance with Practice D2487. 5.2 The gradation (particle-size distribution) curve is used to calculate the coefficient of uniformity and the coefficient of curvature. 5.3 Selection and acceptance of fill materials are often based on ...
Particle Size Classification Equipment In the past, mechanical classifiers were usually selected to operate in closed circuit with grinding mills. These devices require much floor space and have been essentially replaced in large plants, as well as small, by hydrocyclones.
