During the last decade numerous protocols have been published using the method of ball milling for synthesis all over the field of organic chemistry. However, compared to other methods leaving their marks on the road to sustainable synthesis ( microwave, ultrasound, ionic liquids) chemistry in ball mills is rather underrepresented in the knowledge of organic chemists.

Ball Mill. The ball mill's basic concept dates back to prehistoric times when it was used to grind flint for pottery. A pharmaceutical ball mill is a type of grinder that is used to grind and combine materials in the production of different dosage forms. Impact reduces the size of the balls as they fall from near the top of the shell.

Ball mills and agitated media mills work according to a simple principle. The balls are freely movable grinding media in a vertical or horizontal drum. The drive sets this drum, and therefore also the balls, in motion. The material to be ground is then crushed between the balls by impact and shear forces.
