Discrete approximation: particle size range is divided into discrete intervals (or size bins) and the number of particles is calculated in each size bin. Continuous approximation: particle size distribution is represented by analytical function vs. radius. Let's consider first discrete approximation of aerosol size distribution. Table 25.2.

The mean size of the material passing the 0.15mm screen can be estimated assuming the bottom size is 1 micron. Particle Sizes Distribution Models. There is a common need to determine the amount of material in the feed at a given particle size. The desired particle size may not have been included in the original particle size analysis.
Many of the particles encountered in mining are characterized by sieves (classifiers). Recent advances in computers, cameras, and software make image analysis practical for samples with sizes larger than several microns in diameter. As particle size decreases, sieving and/or dynamic image analysis becomes more arduous or impossible and laser diffraction becomes the technique of choice.
5 Basic principles of particle size analysis Figure 3 This also means that there cannot be anything like particle size standard for particles like grains of sand. Standards must be spherical for comparison between techniques. However we can have a particle size standard for a particular technique and this

26. Particle Size Distribution Technique Advantages 1) This technique is well-adapted for bulk materials. 2) It is required to produce a separated size fraction for further study. 3) The material flows easily as discrete particles. 4) The …
Study on the Particle Size Distribution (Nano-Particles) of Mining Minerals 241 2.2. Preparation of triaxial body and firing Triaxial bodies in the shape of Tile were prepared after obtaining micro fine crystalline powder of china clay, feldspar and quartz lumps, prepared four samples A1, A2, A3, and B in same ratio of combination mixture.
tangents on opposite sides of the particle profile. Again to insure statistical significance, all measurements are made in the same direction regardless of particle orientation. • Note: Both Martin's and Feret's diameters are generally used for particle size analysis by optical and electron microscopy.
