  • High energy ball milling process for nanomaterial synthesis

    High Energy Ball Milling Process For Nanomaterial Synthesis

    besides materials synthesis, high-energy ball milling is a way of modifying the conditions in which chemical reactions usually take place either by changing the reactivity of as-milled solids (mechanical activation — increasing reaction rates, lowering reaction temperature of the ground powders)—or by inducing chemical reactions during milling (mechanochemistry).,emax - high energy ball mill - retsch,the high energy ball mill emax combines high-frequency impact, intensive friction, and controlled circular jar movements to a unique and highly effective size reduction mechanism. the grinding jars have an oval shape and are mounted on two discs respectively which move the jars on a circular course without changing their orientation.
