A simple ball milling technique was employed using a Spex GenoLyte Model 1200 shaker and for each attempt, individual milling cells for that specific target powder were used to prevent cross-contamination. The milling medium was a 7.9 mm diameter tungsten carbide ball, resulting in a fine powder for each target as starting material.

Structural information on ball milled magnesium hydride …
It was found that ball milling distorts the vibrational spectra due to distribution in stresses over the sample. Cycling of the hydrogen content of ball milled samples results in the spectrum of unmilled samples, while the particle size remains small and hydrogen storage characteristics continue to be better for ball milled samples.

ore dressing ball milling vibrational
A mill load is defined as the instantaneous total charge of a ball mill and is composed of a new feed ore, slurry, water, and steel balls inside the mill (Tang et al., 2015a). Overloading causes "mill spitting ore," coarsening on the particle size of mill outlet, "mill blockage," "belly be filled full," and production process break off.
