<p>A particle suspension handling system comprises, a dispersion means (14), a transport means (46), a cell (18). The dispersion means (14) has a transducer (70) mounted externally of the dispersion means (14). The transducer (70) is arranged, in use, to transfer energy into the suspension. The transport means (46) is located within the dispersion means (14) and is arranged, in use, to recirculate the suspension about a flow path including the dispersion means (14) the cell (18). The system (10) also includes an outlet means (16) including first and second valve members (84,86). In a first arrangement the valve members (84,86) are spaced apart such that a discharge opening from the system (10) is defined. In a second arrangement the members (84,86) abut and provide a flow path of substantially constant cross-section about the outlet means (16). <IMAGE></p> |
