ABSTRACT:
A two stage rotary pulp screening device has two screens in line within a single chamber. The accepts from the second screen can be recirculated to the primary screen as an integral part of the device. The improvement comprises a second screen within the chamber, downstream and co-axial with the primary screen and having a diameter at least as large as the primary screen, the impeller extends axially in a downstream direction within the second screen and has a body shape with a circular axial cross section whose diameter increases from the outlet end of the primary screen in the downstream direction, second impeller blades radiating from a downstream portion of the impeller for the length of the second screen, and second pulp stock discharge outlet from exterior of the second screen.
