Nov 15, 2017 1. Introduction. Ball milling is an efficient method to produce nanomaterials by conventional top-down approaches [1,2].The properties of the resulting nanomaterial depend on the milling conditions (e.g. dry wet milling, temperature, properties of the balls, and chemical additives) .Material–ball collisions or turbulence in the stirred media [4–8] change the structure or the surface.

Ball Milling. Ball milling machines may be used to reduce particle size, mix or blend materials, or change particle shape. Workers may be exposed to nanomaterials during this process primarily when loading or unloading materials into the ball mills. Witschger et al.  investigated aerosol emissions during the high energy ball milling process.
