The ordinates on the left and right sides of the curve are the distribution rate of each grain size of raw materials in spillover (ε spillover) and grit (ε grit), respectively. Through the grain size distribution curve (Fig. 1), the value of particle separation can be checked, and the classification efficiency can also be evaluated.

For example, size distribution data obtained form a laser diffraction measurement are plotted as a cumulative size distribution shown in Figure 2. It shows that D50 is 200 μm, which represents 50% of particles are below 200 μm (i.e., the median diameter). Similarly D10 and D90 are 74 μm and 411 μm, indicating that 10% of particles are below ...

The grain size distribution clearly develops from a bimodal distribution to a monomodal (unimodal) one; the modal value of r equ = 3.8 px remains constant, while the mean value decreases from 11.1 to 5.3 px. This development seems to be due to a decrease of the larger grain size fraction while the small grain size fraction (at 12.5 px ...

To an outsider to the pharmaceutical industry, the notion of D-values (e.g. D10, D50, D90) being a measure of particle size and distribution is a difficult concept to accept. Basic statistics and a common understanding of distributions might dictate that, provided one is allowed to assume that the particles are relatively spherical, the most ...

Whereas particle size distribution refers to the measurements of particle size for a given sample. Particle size distribution can be used to determine whether or not the particles are homogenous (size, shape, and distribution are equal). Particle size can also be used to determine if there is an excess of one particle type over another.

where F is the amount of −37μm fraction and d80 is the 80% passing size. If the slope of the curve between two points is increased then the size distribution will become narrower. It is clear that when both d80 and F of the process are decreased the slope of the distribution curve increases and a narrower size distribution is obtained.
