In contrast, if the higherenergy millingwas applied in the form of ahighBP ratio (Yuan et al., 2009), ormillingwas performed in a magnetoball mill(Uni-Ball-Mill5) with the possibility of controlling thetypeof acting forces (Lohse et al., 2005), or othertypesofmillwere used (a GN-2ball mill) (Xinkun et al., 2001) or ahigh-energy...Email:[email protected]
Lee et al studied the Phase evolution of Fe 2 O 3 nanoparticle duringhigh energy ball milling.High-energy ball millingof α-Fe 2 O 3 powder was performed in a stainless steel attritor at a speed of 300 rpm for 10–100 h. The powder-to-ballmass ratio was 1:50 with a powder mass of 100 g.

High Energy Ball Milling. In discussions onhigh energy ball milling, the more generic term "ballmills" is often used in place of the terms "stirredballmills" or "Attritors," but the differences between thetypesof mills are quite distinct.
Different types of high-energy ball mills have been developed, including theSpex vibrating mill,planetary ball mill,high-energy rotating mill, andattritors. In the nanotube synthesis, two types of HEBM mills have been used: a vibrating ball mill and a rotating ball mill.
Compressibility of a nanostructured Al–5AlN composite powder synthesised viahigh energy ball millingfor various times was studied by means of a modified Heckel equation. Since workhardening and morphological changes take place bymillingevolution, the compressibility was consequently affected.

The novel size reduction mechanism of theE maxunites the advantages of different mill types:high-frequency impact(mixer mill),intensive friction(vibratory disc mill) andcontrolled circular jar movements(planetary ball mill) allow for unrivaled grinding performance. This unique combination is generated by the oval shape and the movement of the grinding jars.
During the high-energy ball milling process, thepowder particlesare subjected to high energetic impact.Microstructurally, themechanical alloying processcan be divided into four stages: (a)initial stage, (b)intermediate stage, (c)final stage, and (d) completion stage.
TheHigh Energy Ball MillEmax combineshigh-frequency impact, intensive friction, and controlled circular jar movements to a unique and highly effective size reduction mechanism. The grinding jars have an oval shape and are mounted on two discs respectively which move the jars on a circular course without changing their orientation.
