The purpose of screening is to separate contaminants such as shives in mechanical pulp,and stickies,plastics ,sand ,metal pieces,and flakes in recycled fiber. This method employs a screening device and the separation is based on size difference between fibers and contaminants. However,depending on their flexibility and /or geometry,not all of the contaminants that are larger in size than fiber can be captured by the screen.
Screening plates of various slit widths such as 0.10mm,0.15mm, 0.20mm,and 0.25mm have been used in separating contaminants.
|Production area:|| 6~10m|
|Hole size:||φ0.15mm~φ20mm |
|Sieve pore type:||straight hole ,step hole ,tapered hole|
|Slot screen cylinder:||milled screen cylinder,wedge wire screen cylinder|
Wedge wire screen cylinder.
Wedge bar would be selected according to different raw material and different processing position in order to meet customer's special request.
Slot width tolerance:
> Slot width less than or equal to 0.02mm . Slot width is no less than 0.01mm while controlled within 0.02mm.
> Slot width which is equal or greater than 0.25mm.The slot width be controlled within standard width range ±0.02mm .
Chroming thickness is 0.20-0.3mm
Surface hardness≥ HRC:60-66(HV700-900)
Drilled screen cylinder Benefits
- Cleaner pulp
-High processing capacity
-Lower operating costs
Sieve pore diameter deviation≤ 0.10mm.
Deviation of pitch and line spacing≤ 0.10mm.
Effective thickness deviation:≤ 0.20mm.
it can be used as paper stock screening equipment before paper machine or fine screening
in pulp production system.
Impurities in the outside of the screen cylinder and get rid of the screen rid of the screen cylinder
in the centrifugal force generated by rotor's rotation,separate the impurities from the paper machine
to be in proper running with less broken paper. Great throughput with more long fiber,lower power
consumption,high screen efficiency with less rejects.the capability may be different according to different
pulp variety and concentration,so the capability in the below chart is only used for choosing the model.
The in flow pressure screen has good adaptability and high production capacity.
High efficiency, lower energy consumption, lower operation cost.
Reliable Performance -High strength automatic welding increase screen cylinder's intensity. Smooth welding joint, no workpiece deformation and high size precision including roundness\verticality etc and achieve more evenly clearance between rotor and cylinder.
Manufacturing -Compared to slotted screen cylinder,open area of hole screen cylinder will increase 30% and production capacity will increase highly at the same time.
Quality- Numerical control machine endures physical dimension and hole pitch,adopted tapered hole will improve pulp flow,screen plate ,burr-free and no fiber string after mechanical polishing .
