<p>A method of regulating the overflow from a cyclone, hydrocyclone or similar device (1) comprises the steps of passing the overflow (1C) to the main inlet (3C) of a fluidic valve (3) and passing at least a proportion of the underflow (1B) from the device (1) to the control inlet (3B) of the said fluidic valve (3). The flowrate of the overflow (1C) leaving the device (1) is maintained despite variations in feed flowrate or feed flow pressure (1A). Preferably, the underflow (1B) or proportion thereof is passed through a restriction (2) before being passed to the control inlet (3B) of the fluidic valve (3).</p> |
