Ball milling: a green technology for the preparation . The use of ball milling to obtain cellulose nanocrystals was also explored by the group of Yu, who extracted CNCs from ball-milled stone via a multi-step process. 40 Douglas-Fir stone chips were firstly hammer-milled to stone flours, which were then treated using a planetary ball mill at 270 rpm.
