Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.

Attritor ball mill is a kind of ultrafine grinding equipment with high output and energy saving.. With the development of science and technology, there are more and more applications of ultra-fine powders in industry. From ultra-fine grinding of metal and non-metal raw materials to deep processing of new composite materials, dozens of minerals are processed.
Place the barrel on the mill and let it run for approximately 2 hours. This will reduce the ore into a very fine dust. This is necessary so the extraction chemicals will be able to react with the ore material. If Ball Milling is not done, very little Uranium will be extracted. After 2 hours of milling, the ore is as fine as Talcum powder.
With all 3 chemicals and the lead balls inside, put the lid on the tumbling barrel and seal it, then set it in the Mill. Turn on your Ball Mill and let it rotate for 2 to 4 hours. As the Ball Mill rotates, the lead balls will crush the chemicals together and reduce them into a super fine powder.
