Process engineering: Particle size reduction techniques

Feb 15, 2005Many particle-size distributions can be represented by the Gaudin-Schuhmann equation: y = 100 (x/x m ) where y is the cumulative percentage of material that is finer than size x, x m is the theoretical maximum size, and is the distribution modulus, which is related to hardness and has lower values for softer materials (0.9 for quartz

Understanding Interpreting Particle Size Distribution

D‾43 = the mean diameter over volume (also called the de Brouckere mean) The example results shown in ASTM E 799 are based on a distribution of liquid droplets (particles) ranging from 240 - 6532 m. For this distribution the following results were calculated: D (1,0) = 1460 m. D (3,2) = 2280 m. D50 = 2540 m.
