A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1– times the shell diameter (Figure ).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
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.

Wet ball milling was used to exfoliate graphite platelets into graphenes in a liquid medium. Multilayered graphite nanosheets with a thickness of 30 to 80 nm were dispersed into N,Ndimethylformamide (DMF) and exfoliated by shearforcedominated ball milling carried out in a planetary mill. After highspeed centrifugation, irregular shaped single and fewlayer graphene sheets (≤3 layers ...
