Method and devices for fractionated separation and for granulometric analysis of particles in suspension in a liquid.

Abstract

Abstract A device according to the invention includes a unit 1 for storing and homogenising the liquid, which unit is equipped with a suction chamber 2 having an opening provided with a screen 3 mounted on a vibrator 4. It includes a centrifuging unit equipped with two interchangeable rotors. One separation rotor includes a stepped conical core 9 defining centrifuging chambers whose diameters increase from the bottom up. It is driven at a constant rate. A second rotor, for granulometric analysis, includes a single chamber. This second rotor is driven by speed increments. One application is granulometric analysis of powders having a particle size less than 50 mu .
