During the high-energy ball milling process, the powder particles are subjected to high energetic impact. Microstructurally, the mechanical alloying process can be divided into four stages: (a) initial stage, (b) intermediate stage, (c) final stage, and (d) completion stage.
This mechanical process provides a way of mixing and combining solids from the scale of a powder particle down to the nano scale. The objectives of milling include particle size reduction (comminution or grinding)." of materials has been a major component of the ceramic processing and powder metallurgy industries for many years.

This process for producing reduced iron comprises: a kneading step of adding water having a temperature of 60-90C inclusive to a mixture comprising a powdery iron oxide raw material and a powdery reducing material and kneading the resulting mixture; a granulation step of granulating the mixture obtained in the kneading step to produce a granulated material; and a reduction step of
The modification effect of iron oxide improved with the grinding time extended from 1 h to 5 h and with the grinding rotation speed increased from 300 r/min to 516 r/min.
These castings are rolled to the required dimensions by the rolling mill to produce steel products. The smelting and refining process for iron and steel in the BF-BOF process involves the carbon reduction of iron ore (Fe 2 O 3) in the BF to make molten iron, and decarburization of molten iron in the BOF to make molten steel. Steel Rolling

The process of froth flotation involves crushing and grinding the ore to a fine size This separates the individual mineral particles from the waste rock and other mineral particles. The grinding is normally done in water with the resultant slurry called the pulp.
An industrial eccentric vibratory mill, type ESM-656 0.5 ks (Siebtechnik GmbH, Germany), equipped with a satellite milling container was used for the milling. The kinematic analysis as well as the mechanical model of the eccentric vibratory mill can be found in numerous publications -.
A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.Working·
Planetary mill: High energy mill widely used for producing metal, alloy, and composite powders. Fluid energy grinding or Jet milling: The basic principle of fluid energy mill is to induce particles to collide against each other at high velocity, causing them to fracture into fine particles.
Mechanical milling is a very convenient and promising way to produce nanoparticles powder (Wang and Jiang, 2007). Grinding mills typically used in the process include the attrition jet, planetary, oscillating and vibration mills, all of which are classified as high-energy mills.
