The high-speed CCD camera system is capable to reach 120 frames
per second, which avoids negative effects of moving particles caused by
slower camera technology. Furthermore, the instrument is equipped with a
powerful LED array light source and telecentric lens system.
The dry dispersion system works via a vibratory feeder and a
software-controlled, height-adjustable feeding funnel. At the end, the
particles pass to a drop chute with a variable focusing funnel. The
falling particles are detected and photographed in real time and
immediately analyzed in terms of particle size distribution and particle
shape.
The optionally available wet dispersion unit consists of a measuring
cell and an external dispersing unit, equipped with a centrifugal pump
and an ultrasonic bath.
