Get PriceThe use of ball milling to obtain cellulose nanocrystals was also explored by the group of Yu who extracted CNCs from ball-milled wood via a multi-step process. 40 Douglas-Fir wood chips were firstly hammer-milled to wood flours which were then treated using a planetary ball mill at 270 rpm. This process was followed by enzymatic hydrolysis .
Get PriceThe time required to obtain a specific particle size is often less than in a Planetary Ball Mill even in processes where no interruption in the grinding times are required in Planetary Ball Mills thanks to the more efficient grinding mechanism.
