A replaceable screen structure for a stock screen where stock slurry for making paper is passed through a screen with the rejects going to a reject outlet and the accepts passing through openings in the screen to an accepts outlet, with the screen having projections and a rotor inducing a pulsating induced flow along the profile surface, with projections on the surface having an inclined ramp of less than about 45.degree. and a 90.degree. downstream wall and accepts flow openings between the projections positioned closer to the upstream projection than the downstream projection.

Basket profile for screens

A pressurized dynamic pulp washer in which stock is driven along a stationary wash wire and pulses are generated in the stock to urge liquid through openings in the wash wire. Wash liquid is introduced countercurrent to the flow of stock, and localized mixing and reslurrying occurs.
