  2. Particle-size distribution - Wikipedia

    en.wikipedia.org/wiki/Particle-size_distribution

    The Weibull distribution or Rosin–Rammler distribution is a useful distribution for representing particle size distributions generated by grinding, milling and crushing operations. The log-hyperbolic distribution was proposed by Bagnold and Barndorff-Nielsen [9] to model the particle-size distribution of naturally occurring sediments. This ...

  3. Particle size analysis - Wikipedia

    en.wikipedia.org/wiki/Particle_size_analysis

    Particle-size analysis also helps the effectiveness of SAG Mills when crushing material. In the building industry, the particle size can directly affect the strength of the final material, as it observed for cement. [18] Two of the most used techniques used for the particle size characterization of minerals are sieving and laser diffraction.

  4. Particle size - Wikipedia

    en.wikipedia.org/wiki/Particle_size

    Particle size is a notion introduced for comparing dimensions of solid particles (), liquid particles (), or gaseous particles ().The notion of particle size applies to particles in colloids, in ecology, in granular material (whether airborne or not), and to particles that form a granular material (see also grain size).

  5. Particle technology - Wikipedia

    en.wikipedia.org/wiki/Particle_technology

    Particle velocity can be calculated using the Doppler frequency from any signal, while the phase difference between two detectors determines particle size. [ 3 ] Fraunhofer diffraction : When a particle is at least 10 times larger than the laser wavelength and the scattering angle is 30° or smaller, the light intensity distribution pattern can ...

  6. Micronization - Wikipedia

    en.wikipedia.org/wiki/Micronization

    The term micronization usually refers to the reduction of average particle diameters to the micrometer range, but can also describe further reduction to the nanometer scale. Common applications include the production of active chemical ingredients, foodstuff ingredients, and pharmaceuticals. These chemicals need to be micronized to increase ...

  7. Micromeritics - Wikipedia

    en.wikipedia.org/wiki/Micromeritics

    Clinically, the particle size of a drug can affect its release from dosage forms that are administered orally, parenterally, rectally and topically. The successful formulation of suspensions, emulsions and tablets; both physical stability and pharmacological response also depends on the particle size achieved in the product. [2] [3] [4] [5]

  8. Malvern Panalytical - Wikipedia

    en.wikipedia.org/wiki/Malvern_Panalytical

    Malvern Panalytical is a Spectris plc company. [6] The company is a manufacturer and supplier of laboratory analytical instruments. [7] [8] It has been influential in the development of the Malvern Correlator, [9] and it remains notable for its work in the advancement of particle sizing technology. [10]

  9. Mesh (scale) - Wikipedia

    en.wikipedia.org/wiki/Mesh_(scale)

    Mesh is a measurement of particle size often used in determining the particle-size distribution of a granular material. For example, a sample from a truckload of peanuts may be placed atop a mesh with 5 mm openings. When the mesh is shaken, small broken pieces and dust pass through the mesh while whole peanuts are retained on the mesh.
