F. Delogu, G. Mulas, in High-Energy Ball Milling, 2010. 5.2 Fundamentals of mechanical alloying processes in ball mills. A ball mill is a relatively simple apparatus in which the motion of the reactor, or of a part of it, induces a series of collisions of balls with each other and with the reactor walls (Suryanarayana, 2001).

High energy ball milling process for nanomaterial synthesis
2021-3-8 For all nanocrystalline materials prepared by high-energy ball milling synthesis route, surface and interface contamination is a major concern. In particular, mechanical attributed contamination by the milling tools (Fe or WC) as well as ambient gas (trace impurities such as O 2, N 2 in rare gases) can be problems for high-energy ball milling ...
