Ball mills are used for grinding materials such as mining ores, coal, pigments, and feldspar for pottery. Grinding can be carried out wet or dry, but the former is performed at low speed. 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. An open source ball mill has been designed that can be fabricated with a 3D printerLikewise both system produced by Fritsch and Retsch, the developed system produced by Evico-magnetics, allowing RBM but at very high gas pressure that can reach to 15,000 Ball Mill an overview ScienceDirect Topics
