A Guide to Particle Size Distribution Weighting

Jun 11, 2019· The bell-shaped curves represent the differential distributions weighted by number, dN/dD, or by volume, dV/dD. The sigmoidal curves represent the cumulative distributions weighted by number, C N (D), or by volume, CV(D). It is likely that the initial measurement calculated dV/dD, from which, by integration, C V (D) was established.. Subsequently, to establish the un-normalized dN/dD,

[Whitepaper] Methods of Particle Size Distribution D

The most commonly used metrics when describing particle size distributions are D-Values (D10, D50 & D90) which are the intercepts for 10%, 50% and 90% of the cumulative mass. By calculating the relative mass for each particle and summing to get the total mass it is possible to obtain D-values when the particles are arranged in ascending order.

Particle Size Distribution Functions:

Moments of Particle Size Distributions: In order to use a particle size distribution it is often desired to obtain a weighted value from the distribution. Additionally, many analytic techniques yield different moments of the distribution so it is important to consider the relationships between different moments.

Calculating and Plotting Size Distributions

The size modulus is a measure of how coarse the size distribution is, and the distribution 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

Particle size distribution :: Anton Paar Wiki

When using laser diffraction, the two most common visual representations are the density or frequency distribution (q 3), see Figure 2, and the cumulative curve (Q 3), shown in Figure 3.The former displays the probability of finding a particle with diameter d in the population, while the latter shows the percentage of particles which are smaller (undersize) or bigger (oversize) than diameter d.
