The high-energy ball milling technique is simple and has high potential to scale up to produce tonnage quantities of materials . However, a serious problem of this technique is the contamination from milling media (balls and vial) and/or atmosphere.
The high energy ball mill can impose to the balls, velocities of the magnitude of meters per second. It has been stated that the impact of these balls at 3.6m/s could correspond to a kinetic energy of about 30mJ and a powder temperature increase of 250°C. 2.1. MECHANICAL DISPERSION
the other high energy . While a number of ball mills ingenious milling devices were developed early in the cen-tury, the one high energy ball mill that has been adopted by industry was invented by Szegvari in 1922, in order to quickly attain a fine sulphur dispersion for use in vulcaniza-tion of rubber.
High Energy Ball Milling. In discussions on high energy ball milling, the more 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.
High-energy ball milling is a simple, effective and productive way to produce various nano-crystal powders in high-energy planetary ball mills . High reactivity and small particle size can facilitate the production of high-
High-energy ball milling is a relatively new technique that has applications in processes for obtaining nanostructured materials, or it is used in solid reactions. In the milling process, several parameters as the milling time, rotation speed, temperature, diameter and number of balls, container
route is described as high energy ball milling (HEM). The definition of Reactive Milling (RM) is suitable if during milling a chemical reaction is wanted and observed. The advantage here can be an ultra-fine dispersion of particles in a matrix (e.g. Ag-SnO2 where the starting powder is AgO2 + Ag3Sn) .
