8%, and n is the slope of the line (Svarovsky, 1981). Lower values of n are associated with a more scattered distribution, while higher values of n will imply an increasingly uniform particle structure. 23) where Y is the cumulative weight fraction under size x, x0 the parameter related to the maximum particle size, m is called the Schuhmann slope, and r is the ratio of x0 to the size modulus. Materials with a normal distribution of particle size are relatively rare and are found chiefly among the particulate produced by chemical processes like condensation or precipitation.

Some of these mentioned functions will be reviewed below. 5. Size Distribution Functions There are many different types of size distribution functions, either in cumulative or relative percentage frequency form. , 1986; Peleg and Normand, 1986); and the Griffith and Johnson’s SB function (Yu and Standish, 1990). Some of these distributions, of common use in characterizing food powders, will be reviewed. 21) k where Y is the cumulative weight fraction under size x, k is the characteristic size of the distribution, and m is the measurement of the distribution spread, also called the Schuhmann slope.
