ABSTRACT:
A dry particle-size distribution measuring apparatus and method is provided for suspending a plurality of bristle members across a support surface of a dispensing trough with bristles being arranged to contact and disperse any clusters of particles to a primary state prior to releasing the particles to a sample flow cell. A source of light can irradiate the sample flow cell and a detector unit can measure any scattered and/or diffracted light to provide corresponding signals. A control unit can determine the size and distribution of particles from the corresponding signals. The bristle members can be mounted on a brush unit that is directly mounted on the trough and both the trough and the brush unit can be driven by the same vibrator unit.
