Get PriceAug 10 2020 Ball mills are a special instrument used to break up hard solids into a fine powder. They are similar to rock tumblers in that the instrument is a rotating container filled with heavy balls to grind the substance into powder. Ceramic material crystalline compounds and even some metals can be ground up using a ball mill.
Get PriceOne of the few things I had to buy for this project aside from the casters was the steel balls. I found these online. They were quite inexpensive. I went with 58 inch diameter balls which seem to work well in a mill this size. I have been powering the ball mill with my bench variable power supply so I could fine tune the rotation speed.
Get PriceWiki 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.
