Ball mill - Wikipedia

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may …

Piezoelectricity drives organic synthesis | Science

The ball-milling process is well known and widespread in industry. The piezoelectric catalysts are mature materials with good recyclability and therefore relatively low cost. In contrast, catalysts for photoredox reactions are generally expensive and difficult to recycle because they are often molecularly soluble or uniformly dispersed in media to achieve quantitative excitation.
