    Mechanism of Achieving Nanocrystalline AIRu By Ball Milling

    1. Introduction. High-energy ball milling is a complicated process employed in solid reactions for obtaining nanostructured materials, in powder form, with an average particle size of less than 100 nm. The planetary mill is one of high-energy ball mills, which is used for efficient and precision milling.Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and ...
