Agglomeration In Ball Mills

  • Effects of ball-milling treatment on physicochemical .

    Ball-milling at 400 rpm gave the highest surface area of 412 m 2 g −1 while higher rotation speeds decreased the surface areas due to agglomeration. Moreover, ball-milling resulted in the emergence of amino- and hydroxyl groups on the surface which were observed by Fourier transform infrared spectroscopy, and partial oxidation of the surface .
