mill. However, it is less used than a hammer mill in a dry mill industry. There are some reasons. First, the maintenance of the appropriate roller gaps is very costly. Also, a roller mill has a difficulty to grind a small and grain with hard shell such as corn. Thus sometimes, it is not appropriate to grind corn.

Corn ethanol - Wikipedia

Corn ethanol is ethanol produced from corn biomass and is the main source of ethanol fuel in the United States.Corn ethanol is produced by ethanol fermentation and distillation.It is debatable whether the production and use of corn ethanol results in lower greenhouse gas emissions than gasoline. Approximately 40.5% of the U.S. corn croplands are used for ethanol production.


corn ethanol. In addition to reducing the energy and environmental footprint these technologies greatly expand the diversity of products from a corn ethanol plant. The traditional dry mill process produces ethanol and a co-product called distillers grain with solubles, which is sold either wet (as WDGS) or dried (as DDGS) to the feed market.
