For example, oxidedispersionstrengthened alloys are synthesized using a powerful highenergy ball mill (attritor) because conventional ball mills could not provide sufficient grinding energy [38] Intensive research in the synthesis of new metastable materials by HEBM was stimulated by the pioneering work in the amorphization of the NiNb alloys conducted by Kock et al in 1983 [ 39 ]

fabrication of the ball mill, grinding test was conducted with the mill, using limestone as the feed material This was followed by the particle size analysis of the ground product from the mill in order to determine the performance of the mill The design results show that the minimum shaft power required to drive the ball mill is 02025 horsepower, the length of the mill at a fixed mill
