To obtain narrow length and diameter distributions of CNTs and to open the nanotubes for improved sorption capacity for gases, ball-milling is a very useful method. However, it has also been observed that a large amount of amorphous carbon is created which clearly indicates that the tubes are damaged in different ways and that ball milling is a ...
Wet ball milling was used to exfoliate graphite platelets into graphenes in a liquid medium. Multi-layered graphite nanosheets with a thickness of 30 to 80 nm were dispersed into N,N-dimethylformamide (DMF) and exfoliated by shear-force-dominated ball milling carried out in a planetary mill. After high-speed centrifugation, irregular shaped single- and few-layer graphene sheets (≤3 layers ...
The natural flake graphite and the raw coke are fed into the crushing chamber by the compressed air through the feeding ejector, and are distributed in the nozzle around the pulverizing chamber, and the ultra-high-speed airflow is sprayed to the pulverizing chamber, so that the coke powder collides with each other at high speed and rubs into a fine powder, with a fine powder.
