Abstract: Processes for grinding corn, ground corn products, and processes for making ethanol from the ground corn products. In some examples, a process for making ethanol can include introducing a plurality of corn pieces into a mill. The process can also include milling the corn pieces in the mill to produce a ground corn product. Greater than 25 wt % of the ground corn product can have a particle size of greater than 105 μm, as measured according to AOAC 965.22-1966. Greater than 80 wt % of the ground corn product can have a particle size of 425 μm or less, as measured according to AOAC 965.22-1966. The process can also include processing the ground corn product to produce a fermentation mash that can include ethanol and separating at least a portion of the ethanol from the fermentation mash to produce a stillage.
