Aeration and mixing behaviours of nano-sized powders under ...

12/07/2010  The sound assisted aeration of two nano-sized powders, Al 2 O 3 (40. nm) and CuO (33 nm), have been investigated in a laboratory scale fluidized bed.. Acoustic fields of intensities larger than 135 dB and frequencies in the range 100–125 Hz are required to obtain a homogeneous fluidization.Under these conditions mixing between powders has been qualitatively characterized

Role of Sound Vibration during Aeration of Nano-Sized Powders

The behaviour of two different nano-sized powders, SiO 2 and Al 2 O 3 , has been investigated. The properties of the powders are reported in Table I. The size distributions of the powders as received are reported in Fig. 1. Analysis of data shows that both the powders form relatively large agglomerates, with a Sauter diameter of 250 and 190 nm for Al 2 O 3 and SiO 2 respectively. Typical ...

The present work is focused on the characterization of the aeration behaviour of two different nanopowders, Al2O3 and Fe2O3, under the application of acoustic fields of different intensities (125–150 dB) and frequencies (50–300 Hz). The two nanopowders showed slightly different behaviours; in particular, Fe2O3 is generally characterized by a better fluidization quality.
