Why and how to choose solvent in ball milling? The planetary ball mill can be used for dry grinding and wet grinding. The effect of wet grinding is better than dry grinding, It is believed to be more efficient to get smaller particles as the liquid helps to lower the surface energy of particles.

Mixing solid reactants in a ball mill is a promising means of avoiding the copious solvent waste associated with most chemical syntheses. et al. now report that adding a piezoelectric catalyst to the mix can promote bond formation through apparent electron transfer cycles (see the Perspective by Xia and Wang).

However, ball-milling time was not an important factor for lignin extraction without hydrothermal treatment (Fig. 2A). The AIL content of the solid residues was similar after extraction using the same solvent regardless of ball-milling time. As the results, the single step of ball-milling might be not enough to sufficiently isolate lignin fraction.

However, for samples in which the solvent is not an issue, the solvent-free method is generally less efficient. Workflow and clean-up issues related to solvent-free MALDI analysis were considered serious handicaps for high-throughput applications. These reservations are partially overcome by the vortex and mini-ball-mill (MBM) methods [7, 8, 9].
