Milling was then performed in 80% ethanol for 30–120 minutes using a highenergy ball mill. The mechanical treatment resulted in a reduction of the fibre length and diameter, probably due to degradation of the cellulose amorphous regions. Fibrillation was helped by the wet environment, which facilitated the intrafibre swelling. Longer milling times enhanced the breaking of the hydrogen ...

Get PricePlanetary ball mills are smaller than common ball mills and mainly used in laboratories for grinding sample material down to very small sizes. A planetary ball mill consists of at least one grinding jar which is arranged eccentrically on a socalled sun wheel. The direction of movement of the sun wheel is opposite to that of the grinding jars (ratio: 1:2 or 1:1 or else). The grinding balls ...
Get PriceThe higher the energy density, the greater the probability that more stable agglomerates are also dispersed. It does not matter whether the power input which leads to the existing energy density, is applied with a high speed and low torque or vice versa. With a given bead charge and dispersion time, the dispersion result depends only on the amount of the mechanical power. The torque therefore ...
