  • High Energy Ball Mills for Nano-Scale Grinding

    There are basically two methods of producing nano-scale particles the "Bottom-Up" technique involves synthesizing the particles from atoms and molecules. With the "Top-Down" method the particles are reduced to nanometer size by grinding. Suitable tools for this method are planetary ball mills such as Retsch s new PM-series grinders which provide the necessary energy input.

  • An investigation on the High-Energy Ball Milling of Iron

    Results of high-energy ball milling of Ti and Fe powder mixtures to obtain TiFe intermetallic compound are reported. Previously we used various process control agents (PCAs) to solve a cold welding problem in a SPEX mill. In this work we continue that investigation but without adding PCAs and also using a planetary ball mill.
