(I don't use the small rubber chambers for brass cleaning as I built a larger chamber from 4" PVC that holds more and is easier to seal and open.) Some say "ball mill the BP ingredients using lead balls." Others say, "use glass marbles." I have a .45 Cal lead ball mold for my cap and ball Old Army. Are those large enough for effective ball milling?
Posted 09 February 2012 01:53 AM. I just tested using 100 1/2 inch lead ball media vs 95 nickels and 25 quarters (they took up about the same volume) the lead ball media bp was a little faster. It was milled for six hours. Although neither where clumping to badly the sides of the drum with the nickels where cleaner than the lead ball media drum.
Type of ball mill: • There is no fundamental restriction to the type of ball mill used for organic synthesis (planetary ball mill, mixer ball mill, vibration ball mill, .). • The scale of reaction determines the size and the type of ball mill. • Vessels for laboratory vibration ball mills are normally restricted to a volume of 50 cm3.

Besides amorphization, it is important to understand that ball milling is a technique that can lead to the formation of a microcrystalline (or nanocrystalline) state, where this last state involves particle size reduction without the deformation of the crystalline structure. ...

Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^ where D m = the diameter of the singlesized balls in = the diameter of the largest chunks of ore in the mill feed in mm. dk = the P90 or fineness of the finished product in microns (um)with this the finished product is ...
Worn balls Worn balls perform more poorly than spheres, reduce the grinding chamber in the mill, and increase power consumption. [9] Spherical balls are mostly used for ball mill processes but are ...
This applies particularly to gold and lead ores. ... (1″—1½") balls and possibly tertiary ball mill with 20 mm (¾") balls or cylpebs. To obtain a close size distribution in the fine range the specific surface of the grinding media should be as high as possible. Thus as small balls as possible should be used in each stage.

Lead balls are good but heavy, and the powder made always contains lead, also if the drum is too heavy a cheap mill will not turn it over. Likely you will need to do some trials. a cheap rock tumbler works best with ceramic balls, a fully powered ball mill will work well with lead or brass media.
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.
Wiki says "A ball mill is a type of grinder used to grind materials into extremely fine powder for use in paints, pyrotechnics, and ceramics." Many instructables refer to United Nuclear Ball Mills. Their small ball mill cost between 70 and 80 dollars. For no more than 30 and in 5 minute you can build a ball mill of appreciable performance.
A ball mill, a type of crusher, is a cylindrical device used to grind chemicals or mix compositions. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium, ideally non sparking milling media like lead balls. An internal cascading effect reduces the material to a fine powder.
For instance, if your jar had in inside diameter of 90 mm and your milling media was mm diameter lead balls, the optimum rotation would be 98 RPM. Optimum RPM= .65 x Critical speed (cascading action of the media stops) with dimensions in inches. Share on other sites. whitewolf_573. The motor has been working for 30 minutes, and works good ...
