Fig. 3 shows CNT distributions in extruded composites under different milling conditions. CNT bundles could be observed for the composite under 300 rpm milling for 8 h (Fig. 3 (a)), and many CNT clusters with a size of about 100 nm were dispersed in the composite under 450 rpm milling for 5 h (Fig. 3 (d)). By comparison, CNTs were …
The effects and mechanism of ball milling on the torrefaction process were studied. Ball- and hammer-milled (screen size 1mm) pine sawdust samples were torrefied at three temperatures (230, 260 ...
In this study, modified biochar (BRB) was prepared from rice straw by ball milling technique and used for the adsorption of methylene blue () in wastewater. The BRB was characterized by SEM, FTIR and XPS, and the adsorption model and Box-Behnken design were used to optimize the five influencing fa …

To investigate the change of structure and physicochemical properties of wheat straw in ball milling process at cellular scale, a series of wheat straws samples with different milling time were produced using an ultrafine vibration ball mill. ... A multitechnique approach was used to analyze the variati … Regularity and mechanism of wheat ...
Second, a formation mechanism of nanoclusters in ODS steels can be proposed. For a reactive-inspired ball-milling and in those synthesis conditions, ball-milling initiates the nucleation of Y, Ti and O enriched nanoclusters with a mean radius of 0.8 nm. At the end of ball-milling, the nucleation is far from being completed.
Conventionally, the tooth feed of a ball-end milling process has been low (said 0.1–0.2 mm), while the path pick is comparably large (said 0.5–1 mm).In most conventional operation, the feed-to-pick ratio η is usually below one-third. However, the trend in die/mold manufacturing is towards high-speed hard machining in order to …
