Working of Ball Mill. The ball mill works by introducing the material to be ground into the feed hopper. The material is then pulled into the mill by the rotation of the drum. As the drum rotates, the balls inside the drum strike the particles, breaking them down into smaller pieces. The ground material is then discharged through the discharge ...
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.

Pharmaceutical uses of Ball Mill 1. The small and average capacity ball mills are used for the final grinding of drugs or for grinding suspensions. 2. The maximum capacity ball mills are used for milling ores prior to manufacture of pharmaceutical chemicals. Advantages of Ball Mills 1.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium.
3. The ball mill is very noisy machine, particularly if the casing is of metal, but much less so if rubber is used. 4. Relatively long time of operation. Critical speed of ball mill: The faster the mills are rotated the further the balls are carried up inside the mill and the greater the power consumption and capacity of the mill.
