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.
Comminution Crushing Milling in a ball mill Powder produced – Brittle: Angular – Ductile: flaky and not particularly suitable for P/M operations Mechanical Alloying Powders of two or more metals are mixed in a ball mill Under the impact of hard balls, powders fracture and join together by diffusion 70 71.
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.
