- 3. Application & Features Main Speci cations In series with the Offset Pulper, the newly developed Ragger by Parason is efficient in easy and effec ve removal of contaminants like wires, rags, strings, plas cs with the help of Ragger rope. The Ragger is easy to install with both horizontal and ver cal types of pulpers. The me delay between the running of motors is adjustable as per your convenience. The speed of Ragger opera on can be set as per the level of contaminants and produc on rate. Pneuma cloadingandrelievingoftheloadingropeareavailable.

- 4. Application & Features Main Speci cations Parason Asymmetric Fiber Saver (AFS) is a pulper detrashing machine for both low consistencypulperandhighconsistencybatch pulper. In the Asymmetric Fiber Saver, the rotor screen unit is arranged Offsetally to the asymmetrical machine housing. The specially designed Parason AFS is capable of removing upto70%contaminantsfromthepulp. The equipment maintains stable troublefree produc on at the pulper loop thus reducing the load on the pulper. The asymmetric design helps to omit the blockages, reduce wear resistance and rotor damage which also makes it difficult for the bigsized contaminants to flowagainstgravity. Reduces fiber loss in the pulping process Efficient & power saving process ASYMMETRIC FIBER SAVER AFS Model AFS 08 0.8 55 AFS 15 1.5 75 AFS 30 3 110 Volume (m³) Power (kW) Results of flow simulation performed using latest computational fluid dynamics software Minimum maintenance requirements Troublefree opera on Longer service life Key Benefits: Reject Feed Accept
