James also points out that scaling up ball-mill processes is not always straightforward. 'It would also be interesting to try techniques such as screw extrusion, which might be more scalable.' Baek explains that the group now hopes to find even more efficient catalysts and design a device that would allow continuous ammonia production.
AVEKA's cryogenic hammer mills can typically reduce the particle size from small pellets down to the 100s of microns. Cryo-milling can be used for: Cryo-milling can be used for: Reducing the material temperature below its glass transition temperature (T g ), which is the point at which a polymer goes from a brittle, glassy state (low ...
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 …
