Ball milling: a green technology for the preparation and functionalisation of nanocellulose derivatives Carmen C. Piras, a Susana Fernandez-Prieto´ b and Wim M. De Borggraeve *a Ball milling is a simple, fast, cost-effective green technology with enormous potential.
Ball milling is an important method for the preparation of materials both for the investigation of fundamental physical properties and for a number of possible commercial applications.
The QM-QX-20L omnidirectional planetary ball mill was adopted, the milling speed was set to 200 rpm, and the milling time was 0~36 h. After milling for 0 h, 6 h, 12 h, 24 h and 36 h, a proper amount of powder was taken for characterization test. The LWHEA powders were sintered by SPS-3.20MKII spark plasma sintering system of Nippon Mining Co., Ltd.
The ball milling was done for AA7068 metal powders for three different speeds at 150, 200 and 230 rpm and at different time durations such as 0, 5, 10, 15, 20 and 25 hours.
One disadvantage of ball milling is that abrasion of the milling media may occur. This has to be minimized by choosing appropriate materials for the milling vial and balls, respectively. A further disadvantage is that the milling can produce amorphous debris, to the extent that recent work on ball milled Al 2 O 3 indicated that the sample ...
The preparation of CNFs by ball milling from softwood pulp was systematically studied by multiple factor analysis using the Taguchi method and ANOVA analysis. Among the major single factors possibly influencing the production of CNF, milling ball size was a factor that can be neglected, while mass ratio of milling ball to cellulose pulp was the ...
On ball milling, the particle size got reduced from 60 μm to 148 nm by 405 times and the surface area increased from 0.249 m2/gm to 25.53 m2/gm i.e. by more than . Measurement of surface free energy as well as work of adhesion found that it increased with increased duration of ball milling.
After ball-milling for 30 hours, the obtained dark dispersion was placed quietly to let large pieces subside completely, and then was subjected to centrifugation at 4000 r.p.m. for 30 min to remove any macroscopic aggregates using a TGL-10B centrifuge, giving a black suspension with single- and few-layer graphene sheets stably suspended in the ...
