1970's and recent clean air legislation have contributed to an expanded drymill industry. Currently legislative issues are before Congress that could triple the demand for ethanol as an oxygenate component in gasoline. This increased ethanol demand will likely come from the drymilling of corn thereby offering an increased amount of coproducts.

November 1, 2023 | By Scott Jenkins Milling is a common technique for controlling particlesize distribution (PSD) in solid products through size reduction and surface modification. Broadly, mills can be categorized as wet or dry mills, and these two categories are each further subdivided by how comminution is achieved.
