The 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 ...
ABSTRACT Wet flue gas desulfurization (WFGD), using limestone with forced oxidation (LSFO), is a common Flue gas desulfurization (FGD) process where limestone reacts with SO2 to produce gypsum (CaSO4.2H2O). In South Africa, Eskom's Kusile Power Station utilizes conventional wet ball milling to grind high-grade limestone (96% CaCO3) to 95% …
