Abstract

A particle suspension handling system comprises a dispersion unit, a transport element, a cell and an outlet region. The dispersion unit has a transducer externally thereof, which is arranged, in use, to transfer energy into the suspension. The transport element is located within the dispersion unit. The transport element is arranged, in use, to recirculate the suspension about a flow path including the dispersion unit and the cell. The outlet region includes first and second valve members. The valve members can be arranged in a first configuration wherein they are spaced apart such that the space between them defines a discharge opening via which a fluid or the suspension exits the system, in use. The valve members can also be arranged in a second configuration wherein they abut and a flow path of substantially constant cross-section is provided about the outlet region.
