4 Conclusions
The studies of the influence of the size reduction
method on the physical properties of ground barley were
conducted using four particle size fractions in the range
100 < x < 315 µm. The elongation and the fractal
dimension were determined to characterise the particle
form. For the fraction 100 < x < 160 µm, the influence
of the small particle size prevails in the physical
properties examined. In this range it is to be assumed
that the ratio of adhesive forces to weight forces is higher
than in the case of the larger particle fractions.
