Influence of ball/mill ratio on the characteristics of Ni-Al blends mechanically activated in a ball mill was explored. Burning velocity, microstructure of composite particulates, parameters of XRD diffraction patterns, density of green compacts, and their elongation during combustion were measured as a function of the overall mass (m) of the balls placed in the vial. Variation in ball/mill ...

The majority of grinding balls are forged carbon or alloy steels. Generally, they are spherical, but other shapes have been used. The choice of the top (or recharge) ball size can be made using empirical equations developed by Bond (1958) or …

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

Nanostructured (Fe0.5Ni0.5)92Zr5B3 alloy was prepared by milling a blend of pre-alloyed Fe50Ni50 precursor and high purity chemical elemental powders of Zr and B in a high-energy ball mill setup. Rietveld refinement of the X-ray diffraction pattern of the final sample (30 h of milling) revealed presence of two Fe–Ni rich phases [disordered fcc γ–(Fe,Ni) alloy with Zr and B and the ...

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
