The high energy ball milling technique permits production of composite powders suitable for application in thermal spray processes. Different milling systems are compared concerning their potential for production of composite powder feedstock for spraying processes. Hard phase materials like carbides or oxides are incorporated into various metallic.
High-energy ball-milling was used in several works to produce nano-LN. Spex Mixer Mill 8000 is one of the most commonly used ball mills for this purpose. In general, dry grinding with one ball with a diameter of around 1 cm was used in these processes with grinding times as long as 5–20 h [13,15,20–22].
The high-energy ball mill processing can be divided in three main groups according to the mechanisms involved and or the purpose envisaged Mechanophysical conditioning, Mechanochemical synthesis.
High-energy ball-milling of powder mixtures of zincite (ZnO) and iron (α-Fe) at different weight ratios was performed in air using a planetary ball mill with a stainless steel milling assembly. Structural and microstructural changes during the ball-milling (up to 30 h) were monitored using X-ray powder diffr.
In discussions on high energy ball milling, the generic term “ball mills” is often used in place of the terms “stirred ball mills” or “Attritors,” but the differences between the types of mills are quite distinct. And, depending on your application, you may find that one type of high energy ball milling is appropriate for.
This is a first systematic report on the synthesis of completely nanocrystalline metals by high-energy deformation processes. Pure metals with body-centered cubic (bcc) and hexagonal close-packed (hcp) structures are subjected to ball milling, resulting in a decrease of the average grain size to ≈9 nm for metals with bcc and to ≈13 nm for metals with hcp crystal structures.

STUDY ON THE EFFECT OF HIGH ENERGY BALL. 123 Mechanical Alloying or High Energy Milling Mechanical alloying was originally invented as a method to manufacture oxide dispersion strengthened nickel alloys It is a high energy ball milling process where alloying is the result of the repeated fracture and cold welding of the component particles.
The High Energy Ball Mill Emax combines high-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.
High-energy ball milling is a simple and cost effective method for the large-scale production of fine powders [10–12]. Planetary ball mill is a commonly used high-energy ball mill. Kim and Saito  found that MgAl2O4 spinel could be obtained from planetary ball .
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.

Milling was then performed in 80 ethanol for 30–120 minutes using a high-energy ball mill. The mechanical treatment resulted in a reduction of the fibre length and diameter, probably due to degradation of the cellulose amorphous regions. Fibrillation was helped by the wet environment, which facilitated the intra-fibre swelling.
