Ball mills are used often in scientific work to reduce the particle size, eliminate agglomeration, change the shape of particles, provide for mechanical alloying, mixing, producing powders and changing materials properties. [2] An open source ball mill has been designed that can be fabricated with a 3D printer for a few hundred dollars. [3]
