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.
A ball mill is a rotating drum with dozens of lead balls inside. The 3 chemicals are loaded into the ball mill, along with the lead balls, sealed shut and allowed to rotate for anywhere between 1 and 24 hours.

I thought I would try it out as a ball mill, so I cast up a large batch of .575" (58 cal) hard round lead balls. The trouble is that 30 pounds of lead balls only fills it to about 1/3 full.
