Zusammenfassung:	An improved method for screening and fractionation. By using a housing interiorly divided by a screen plate into a primary and a secondary chamber with the secondary chamber further divided by a fluid impermeable wall, a process fluid stream containing particulate material has a second and a third process fluid stream diverted from it. The second stream is outputed from the housing while the third stream is recirculated to the first chamber. It is demonstrated that high screening or fractionation efficiency is obtained by this method.
