Nano Materials

Nanomaterial drying needs to account for dispersion quality, slurry rheology and the behavior of the collected powder. The CNT conductive additive spray drying system focuses on prepared carbon-nanotube slurries, combining feed conditioning, selected atomization and fine-powder recovery. CNT composition, dispersant and solids loading influence pumping, drying and subsequent redispersion.

Compare two-fluid nozzle spray drying for suitable pumpable feeds with spin flash drying for suitable dewatered cakes or pastes. These routes start from different feed forms. Define the solvent, viscosity, moisture target, powder handling and redispersion requirements, then use trials to assess agglomeration and recovery. Nanoscale starting particles do not establish the size of the dried agglomerates.
