Under mechanochemical conditions in ball mills, copper- and vanadium-containing minerals initiate atom transfer radical cyclizations and oxidative couplings, respectively. Only catalytic quantities of the minerals are required, and the reactions proceed either under neat conditions or in the presence of a minimal amount of solvent.

A ball mill is a drum-grinding unit where balls from solid materials (steel, iron, hard alloys, ceramics, etc) are used. Most common are ball mills, where when the drum rotates and the balls rub against the inner walls, the balls are lifted until the lifting angle becomes bigger than the angle of repose. Then the grinding media are again below.

experiment on vanadium oxide by ball mill Ball Mill Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry designs.

Ball mills, along with grinding mills, impact crushers and a variety of other equipment, are used for the reduction of all kinds of materials for all kinds of purposes.
