This chapter reports some fundamental thermodynamic and kinetic aspects of the high-energy ball milling (HEBM) technique. HEBM technology consists in exposing definite quantities of powders to the repeated action of hitting balls, opportunely launched by a BM device. The increased interest in HEBM as an ecofriendly alternative process able …

Horizontal high energy ball-mills are known from academic as well as industrial applications in mechanical alloying (MA) [1-4], high energy milling (HEM) [5] and reactive milling (RM) [6].
The principle of the High Energy Mill (Simoloyer) is based on a horizontally borne rotor which allows an energy transfer in a homogeneous and high efficient way from supplied power to kinetic energy of balls (grinding media). The milling balls are accelerated by the rotating rotor and collide with each other at a relative velocity up to 14 m/s.
