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

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.

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.
