Modified Dry Grind Ethanol Process
Corn processing for ethanol production has been accomplished both by wet milling and dry grinding. The dry grind process has a lower capital investment but suffers from low coproduct value. In the dry grind process, corn is not separated into individual fractions; whole corn is processed for ethanol production. As a result, nonfermentables,

Chapter 18. Feed Milling Processes
Impact grinding is most efficient with dry, low-fat ingredients, although many other materials may be reduced in size by proper screen selection and regulated intake. Most hammermills have a horizontal drive shaft which suspends vertical hammers but for some ingredients, such as dried animal byproducts, a "vertical" hammermill is more efficient.
