This paper focuses on the particle size distribution (PSD) changes during nixtamalized corn kernels (NCK) as a function of the steeping time (ST). The process to obtain powder or corn flour from NCK was as follows: (i) the NCK with different STs were wet-milled in a stone mill, (ii) dehydrated by a Flash type dryer, and (iii) pulverized with a hammer mill and sieved with a 20 mesh. The powder

Particle size distribution of corn stover grind from different hammer mill screens depicted positive skewness in distribution (Mani et al., 2004b). In actual practice, measured geometric mean diameter of biomass particles using sieve analysis is less than the actual size of the particles (Womac et al., 2007)

Overall accuracy of power measurement was calculated to be 0.003 kW. Particle sizes were examined for hammer mill operating factors using ISO sieve sizes from 4.75 to 0.02 mm in conjunction with Ro-tap sieve analyzer. A total specific energy (kWh/Mg) was defined as size reduction energy expended for a particular mill design
