Particle size distribution of barley ground by hammermill.
ABSTRACT INVESTIGATIONS resulted in a better determination of particle size distribution in ground feed samples ob-tained from hammermill. In stabilized operation the average specific surface, as the best fineness parameter, also varies, but the relative standard error lies within ± 3 percent. Particle size distribution of ground barley follows renormalized log-normal distribution and can be il-lustrated as a straight line appropriately. The range of interpretation (0<x<amax) has an important role. Size distribution is to be well described as a straight line on RRB-chart, too. Relationship between standard deviation and average particle size of ground barley samples varies according to parabola curve.
