I N N O V A T I O N [ X ] » creativity.engineered
Depending on mill design, the setpoint may be a compromise between best breakage conditions (high sound level) and limiting liner damage due to ball strikes (low sound levels). For any particular mill filling, there is a mill speed which will maintain the setpoint sound level (and therefore grinding conditions).
For example, oxide-dispersion-strengthened alloys are synthesized using a powerful high-energy ball mill (attritor) because conventional ball mills could not provide sufficient grinding energy . Intensive research in the synthesis of new metastable materials by HEBM was stimulated by the pioneering work in the amorphization of the Ni-Nb alloys conducted by Kock et al. in 1983 [ 39 ].

A Look at the Process of Pelletizing Iron Ore for Steel …
Iron ore must go through a lengthy pre-processing stage before it can be pelletized – a series of steps that work to beneficiate and concentrate low-grade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore.
