The Quest for Nanotechnology and the Evolution of Wet

The Quest for Nanotechnology and the Evolution of Wet

Mar 30, 2017 Dry-milled materials have the tendency to agglomerate after processing, or when later added to liquid, will also tend to agglomerate. This can be avoided when initially mixed with the liquid carrier and processed in a wet media mill. Wet milling encapsulates the dry particle, surrounding it with liquid and preventing re-agglomeration.
