modeling high-energy ball milling in the alumina-yttria system,experimental results from high-energy ball milling of alumina-yttria powder mixtures have been analyzed with models collected from the literature. depending on the milling conditions, either there is formation of an intermediate phase in the alumina-yttria system (yttrium aluminum perovskite, yap), or the sample becomes mostly amorphous. variations due to milling tool material can be accounted.balls for continuous ball milling,balls for continuous ball milling. alumina ball is a grinding media used in ball mill, pot mill, vibrating mill and other fine grinding plants.it has advantages of high hardness, high bulk density and anticorrosion. with the smashing efficiency and scuff-resistance much better than that of common ball-stone or natural cobblestone,it is widely.
