Highenergy ball milling, also called mechanical attrition, can be used to reduce the grain size of materials from many micrometers to 2–20nm (see Mechanical Alloying ) This is a result of the coldworking process creating largeangle grain boundariesFor large scale production of commercial alloys, attrition mills have been largely replaced by the large tumbler ball mills Another type of mill that has been used for pilotsize production is the vibratory tube Mechanical Milling: a Top Down Approach for the Synthesis of
This process can be used for most types of silver powders with techniques such as ball milling, vibratory milling, or attrition milling A feature of these processes is that they The attritor mill is a wet grinding attrition mill It differs from conventional ball mills as it uses much smaller media with diameter less than 5mm, leading to greater media Milling and Mixing Materials Research Institute
