<p>The invention relates to a pressurized screen for the screening of fibre suspensions, having a screen plate cylinder (16) surrounded by a housing (12) and containing a rotor (14). In said rotor there are dilution water pipes (22) directly connected to dilution water nozzles (20) discharging close to the screening surface of said screen plate cylinder (16) and rotating with said rotor (14). The invention also relates to a process for cleaning a fibre suspension in a pressurized screen, where the fibre suspension is diluted during the screening process with dilution water being fed directly from outside said housing (12) to said screening surface. The screen according to the invention is particularly favorable for use in the short circulation of a papermaking machine.</p> |
