What is Cryogenic Milling? Cryogenic milling, or cryomilling, is the process of using liquid nitrogen to lower the temperate of the material and/or the milling process. AVEKA‘s cryogenic hammer mills can typically reduce the particle size from small pellets down to the 100s of microns. Cryomilling …
The choice between wet and dry milling is, in general, unimportant in smallscale milling but is a major technical problem when largescale milling in the metallurgical industries is involved. On purely mechanical grounds it is difficult to see any great difference in fundamental principles between wet and dry milling, since dry milling may be regarded as wet milling with a fluid …

The ballmilling method was a very effective approach to make the starches more active, especially for positions C 1, C 4, and C 6, and especially for C 6. Using the traditional dry process approach, the DS only reached in the current system, which meant that the traditional dry process was not valid for all systems, especially for this one.
Unlike dry milling, wet milling is more straight forward and more forgiving in terms of charging the product. As with dry milling there should be at least 25% liquid to fill the void space plus a bit more to insure the balls are striking product and not each other.
