Pressure screens / sorters

The pressure screens / sorters are in the stock preparation and in the approach flow system in front of the paper and board machine. Contaminants larger than the fibers are eliminated by pressure screens / sorters.

—	Pressure screeen Ahlstrom Moduscreen C4R Used machine ModuScreen C4R Screening and cleaning in one unit The ANDRITZ ModuScreen CR screen is a good solution for heavy particle removal from recycled fiber furnish. The sreen design combines the benefits of HD cleaners and conventional coarse screening in one unit. Typically, the ModuScreen CR is applied in recycled fiber lines, but it also has several other applications in papermaking. Its unique rotating screen cylinder has enabled the ModuScreen CR to be the best technical solution for coarse screening today. Benefits Low maintenance costs Low energy consumption Gentle screening process 100% large impurities removal efficiency Continuous, automatic operation Simple process control Efficient fiber/reject separation – minimum fiber losses	Andritz	Moduscreen C4R	C4R	—

1 Units	Medium cons. screen Escher-Wyss Omniscreen OS 4 Stock consistency up to 4,5 % The intended field of application of the Omniscreen is in screening or approach-flow systems ahead of paper and board machines where it can be used for the continuous removal of contaminants from pulp suspensions. The Omnisorter is designed exclusively for removing contaminants from paper stock suspensions. Admissible contaminants are plastic granules and films, knots, fibre bundles, shives, hair, flakes and simi- lar particles.	Escher Wyss	Omniscreen OS 4	—	—

1 Units	Pressure screen Lamort CH 7 Main Advantages Working consistencies between 2 and 4% with a drilled screen basket, and up to 3.5% with a slotted basket. depending on its Calibration No fractionating of contaminants. Special design of enclosed rotor, avoiding any string formation. Fine screening possible prior to refining. Low specific power. Little space requirement. Easy access thanks to the pivoting casing door which allows checking or quick change of screen basket. Operates with dalled or slotted baskets, without modifications being necessary.
