Calculating and Plotting Size Distributions

modulus is a measure of how broad the size distribution is. Size modulus for a size distribution can be determined from a graph by extrapolating the straight-line portion up to 100% passing and finding the corresponding size value. The distribution modulus can be calculated by choosing two points in the linear portion of the graph, calculating the logs of the sizes and % passing values, and calculating the slope.

What is Particle Size Distribution D50, D50 Particle

Particle Size Distribution D50 is also known as median diameter or medium value of particle size distribution, it is the value of the particle diameter at 50% in the cumulative distribution. Particle Size Distribution D50 is one of an important parameter characterizing particle size. For example, if D50=5.8 um, then 50% of the particles in the sample are larger than 5.8 um, and 50% smaller than 5.8 um. D50 is usually used to represent the particle size

Particle Size Distribution - an overview

08/08/2011  Particle size distribution and size averages are determined by particle counting in a Coulter counter (e.g., Multisizer 3). It provides number, volume, mass, and surface area size distributions in one measurement, with an overall sizing range of 0.4 μm to 1,200 μm. Its response is unaffected by particle color, shape, composition or refractive index. Samples of 20 mg of resin were

Sieve analysis - Wikipedia

After the shaking is complete the material on each sieve is weighed. The mass of the sample of each sieve is then divided by the total mass to give a percentage retained on each sieve. The size of the average particle on each sieve is then analysed to get a cut-off point or specific size range, which is then captured on a screen.
