#متالورژی In this study, aluminum oxide nanoparticles produced by thermal plasma method have been investigated. To evaluate the grain size of these particles, X-ray diffraction patterns were used in three methods: Sherr, William Son-Hall and Warren-Auerbach. Particles are assumed to be spherical and the particle size distribution is logarithmically normal. The particle size distribution was calculated using the results of the X-ray diffraction scheme, which is consistent with the results of…
An artisan chocolate factory started in There is a tour on which you can taste cacao as it is being processed. They're so into the science behind it, their website has diagrams of "particle size distribution" of beans milled by different machines.
Aerosol partitioning theory governs condensation on and evaporation from an aerosol surface, respectively. Condensation of mass causes the mode of the particle-size distributions of the aerosol to increase; conversely, evaporation causes the mode to decrease.
NASA's Mars rover Curiosity cut a wheel scuff mark into a wind-formed ripple at the "Rocknest" site to give researchers a better opportunity to examine the particle-size distribution of the material forming the ripple.
Overview The LPG centrifugal spray dryer provided by Lemar is the most widely used equipment for liquid material drying. It can transform solution, emulsion, paste, suspended emulsion and other liquid materials to powdery or granulated solid materials. Hence, with this ideal drying machine, you can obtain final products with uniform particle size distribution, proper residual water content, bulk density, and perfect particle shape.
The Sun is partially hidden behind the cloud deck at lower center. Note that the colors here aren't circularly centered on the Sun. This is because the particle size distribution of the water droplets composing the clouds varies across the field of view and is different in different clouds; thus the complexity in the structure and coloration of the corona. The conspicuous dark band at right center are gaps between clouds likely generated by gravity waves.
Too many fines in a cement particle, the cement sets too hot and cracks. Too many coarse particles and the strength is adversely affected. Imagine if your #cementplant combined particle size distribution analysis with mineralogical and elemental analysis. How much more efficient would your plant production be?

Sieve Analysis: Test used to assess the particle size distribution of a granular material. A gradation test is performed on a sample of aggregate in a laboratory. A typical sieve analysis involves a nested column of sieves with wire mesh cloth (screen). See the separate Mesh (scale) page for details of sieve sizing. A representative weighed sample is poured into the top sieve which has the largest screen openings. Each lower sieve in the column has smaller openings than the one above. At…
