Abstract (en)
[origin: WO2010089309A1] The invention relates to a hydrocyclone arrangement comprising an especially tangential infeed of the feed pulp, an overflow (19) for discharging fine grains, a conical/cylindrical underflow (1) for discharging coarse grains, and a sensor system (4, 11) for detecting the jet shape or the change in shape of the jet at the coarse-grained discharge end. According to the invention, means (3) for feeding additional water in a directed manner are provided in the area of the transition from the conical part of the underflow to the cylindrical part of the underflow. Furthermore, a throttle valve (7) is optionally formed on the overflow in order to influence the solid flow to the underflow in such a way that a single-jet discharge state approaching the state where the jet is dispersed in different directions is set when a transition from the single-jet discharge (5.1) to the dispersed-jet discharge (5.2) is detected at the underflow after the additional water feeding process has been activated.
