Effects of Grinding Corn with Different Moisture Content on Subsequent Particle Size and Flowability

The objective of this study was to determine the effects whole-corn moisture and hammermill screen size on subsequent ground corn moisture, particle flowability. Treatments were arranged as a 2 × factorial design with two concentrations (14.5 16.7%), each using sizes (3 mm 6 mm). Corn lab-scale 1.5 HP Bliss Hammermill at three separate timepoints create replications per treatment. Ground flowability calculated angle repose (AOR), percent compressibility, critical orifice diameter (COD) measurements composite flow index (CFI). There no evidence for interaction content (MC), size, standard deviation, or metrics. Grinding 3 resulted in decreased (p < 0.041) compared screen. decrease 0.031) from mm, but difference observed deviation. 0.030) compressibility increased mm.
