The effect of foil rotor design on some aspects of pulp screen performance

The performance of three foil rotors was assessed using a range of rotor speeds and slot velocities. Power consumption and pulse strength both increased with increased foil thickness. While screen capacity generally increased with pulse strength, there was not a simple and direct correlation and other factors remain important. Capacity was found to be determined by factors other than simply the greatest magnitude and frequency of backflush pulsations.
