Particle size analysis by laser diffraction in dry
mode is a popular method in many applications. Most of commercial
vibratory systems use only the vibration amplitude to modify the
vibration level.
CILAS has patented a new vibrating system to improve particle dispersion in dry mode. This
new development is based on an electronic optimization. Both frequency
and amplitude, of the vibration cycle are now adjustable on the
vibratory system. Users can then select the frequency in a range from
5Hz and 80Hz as well the amplitude from 5% to 90%.
These parameters can be selected directly on the Standard Operating Procedure (SOP) in order to have a traceable measurement.
By
using the frequency and amplitude couple, thousands of possibilities
are offered to enhance the particle's flowability and to limit the
powder accumulation in the vibratory device. All materials, with all
particle size, morphology and density can now be analyzed easily.
This
new development is very useful in many applications in which the powder
is fine and sticky such as in cement or in catalyst industries.
