Aeration and mixing behaviours of nano-sized powders

2010-7-12  The aeration and mixing behaviours of two nano-sized powders, Al 2 O 3 (40 nm) and CuO (33 nm), have been investigated in a laboratory scale fluidized bed. The fluidization quality of both powders is very poor without application of acoustic fields. Sound intensities larger than 135 dB and frequencies in the range 100–125 Hz improve their ...
