Choosing the right strategy: cryogrinding vs. ball milling ...

cryogrinding can be "wet" (milling materials mixed with cryo-genic liquid) or "dry" (milling chamber is cooled externally). The main advantage of cryogrinding over ball milling (BM) is the suppression of side processes at low temperature. A number of recent studies report that the processing of poly-

Ethanol Production - Dry versus Wet Grind Processing

Traditionally, ethanol from corn has primarily been produced through dry- and wet-milling processes. The majority of U.S. ethanol production is from dry-grind technology. The traditional dry-grind process grinds the whole corn kernel and mixes it with water and enzymes. The mash is then cooked to liquefy the starch further.

Relationship Between Wet Film Thickness and Dry Film Thickness

Dry film thickness is directly proportional to the volume solids of the coating. Therefore, if you apply a wet film of 2.0 mils and the coating has a volume solids of 50%, you can expect the dry film thickness to be 1.0 mils. The equation is given below: Dry Film Thickness (DFT) = Wet Film Thickness (mils) x %Volume Solids. .
