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 (e.g. microwave, ultrasound, ionic liquids) chemistry in ball mills is rather underrepresented in the knowledge of organic chemists.

2016-6-9 I am looking for ways to produce powder from an aluminum bar. I can't find an available grinder/mill, so I am looking for an alternative. I saw a method wherein a steel plate and a steel bar were
2014-6-27 The ball mill is a common piece of equipment in grinding circuits. Modeling the grinding process in a ball mill is a complex task. Balls and individual parti cles of varying sizes and geometries collide at various angles and magnitudes. The process is further complicated by the production of countless offspring particles. To simplify the
Ball milling is a simple, fast, cost-effective green technology with enormous potential. One of the most interesting applications of this technology in the field of cellulose is the preparation and the chemical modification of cellulose nanocrystals and nanofibers.
