In the present study the particles size distribution of ground maize particles was measured with a vibratory sieve shaker with sieve dimension of 2.5, 1.25, 0.63 and 0.5 mm. The grinding process was conducted with a horizontal hammer mill and for it three different sieve sizes were used 4, 6 and 8 mm.
