Corn Milling: Wet vs. Dry Milling - AMG Engineering

The corn dry milling process is a less versatile, less capital intensive process that focuses primarily on the production of grain ethanol. In this process the corn kernels are hammer milled into a medium-to-fine grind meal for introduction to the ethanol production process. The products of a traditional dry grind ethanol facility are fuel ...
