Application：

Provides a practical,economical and proven method to separate long and short fibers in a furnish continuously.Long or short fractions can be channeled to appropriate mutiple grades.In a single grade application,short fractions can by-pass refiners needed onl for long fiber treatment, and the two streams are recombined for preparation of improved stock.

Features：

1、With muli-foil of rotor design,ensure an unified speed of fiber passing through screen slot on the height of whole basket,overcome the phenomenon of increasing consistency effectively.

2、With the reasonable housing design,making a fluidization of screening area,even pulse,high treating consistency,strong fiber fractionation effect.

3、The ratio of long to short fiber is adjustable and maintaining stabilty.

Characteristic：

1、Anti operation pulse impact:The drum ring of this screen drum adopts multi-layer  splicing  and  riveting  fixing  technology,which  can  effectively  offset the  pulse  impact  of  the   slurry  and  avoid  the  cracking  of  the   screen  drum due  to  metal  fatigue  strength,affecting  the  service  life  of  the   screen  drum. 

2、Uniform and high-precision screening seam:The drum ring and screen strip of  this  screening  drum  adopt  welding  free  riveting  technology,which  avoids manufacturing defects such as uneven screening seam and poor accuracy caused by welding thermal deformation during the production process of the screening drum. 

4、Better  slurry  permeability:Due  to  the  more  uniform  and  precise screening  of  the  drum  and  seams,the  slurry   passes  through   more  smoothly. 

5、 Improving the quality of the slurry:The high precision of the screening seam effectively avoids the probability of impurities passing through the slurry,resulting in high screening efficiency and the removal of adhesives as much as possible,thereby achieving the effect of improving the quality of the slurry.
