Between 2004 and 2006, extensive rotor foil and screen basket studies with flow simulations, laboratory studies andpilot and mill-scale trials were carried out to find new ways of controlling the pressure screen throughput conditionsin order to better meet the requirements of different screening applications.

As a base for the foil study, the pressure pulses created by different low consistency foil shapes were compared todetermine the influence of the pulse shape created by the foil on the screening performance. The basket studyfocused on the influence of the flow resistance of a screen basket panel during production flow and suction pulsemodes on the capacity and quality of the screening.
