Abstract
A liquid separating screen member is continuously oscillated, with an amplitude larger than the apertures in the screen member face, from a middle position with substantially the same speed in first and second opposite directions. The screen member separates liquid from the suspension of finely comminuted fiber material and the liquid, which suspension is flowing in the first direction. The oscillation prevents fiber mat build-up on the screen face during movement of the screen face either in the first or the second direction. The amplitude of oscillation may be about one-tenth of an inch, and the frequency of oscillations may be about 6 cycles/sec. with the average speed of oscillation of the screen member in both the first and second directions about 2.4 inches per second, and the maximum speed in both directions about 3.8 inches per second. The frequency of oscillation, which is below the natural frequency of the screen member and associated structures, is about at least two cycles per second.
