古紙パルプ工場機械 & 機器サプライヤー
We supply a complete used Cellwood high consistency dispersing system, including KRIMA Screw Press, KD Disperser and retention towers, originally manufactured by Cellwood Machinery AB (スウェーデン) in 2011.
Cellwood is a well-known European supplier of pulp and paper stock preparation equipment, widely used in deinking plants (DIP), OCC recycling lines and high-quality recycled fiber production systems.
This system is designed to increase pulp consistency, heat and retain pulp, and disperse contaminants such as ink particles, stickies, wax and adhesives, improving the overall quality of recycled pulp.
Main Equipment in the System
1. Cellwood KRIMA Screw Press
モデル: KSR 750 L
メーカー: Cellwood Machinery AB
年: 2011
The KRIMA Screw Press is used to increase pulp consistency before the dispersing stage.
Main Function
-
Thickening pulp from low consistency (3–5%) to high consistency (25–35%)
-
Removing excess water efficiently
-
Preparing pulp for high consistency dispersing treatment
Key Advantages
-
High dewatering efficiency
-
Stable operation in recycled fiber systems
-
Suitable for OCC and deinking pulp lines
Typical Applications
-
Waste paper recycling plants
-
DIP (Deinking Pulp) systems
-
Stock preparation lines for packaging paper mills
2. Cellwood KD Disperser
The KD Disperser is the core equipment of the dispersing system.
It operates under high consistency and high temperature conditions to disperse contaminants in recycled pulp.
Main Function
The disperser breaks down and disperses:
-
Ink particles
-
Stickies
-
Wax
-
Hot melts
-
Adhesives
-
Other contaminants from waste paper
This process significantly improves pulp cleanliness and finished paper quality.
Operating Conditions
Typical operating parameters:
-
Pulp consistency: 25–35%
-
Temperature: 90–120°C
-
High shear mechanical dispersion
Benefits
-
Reduces visible dirt and black spots
-
Improves fiber dispersion
-
Enhances recycled pulp quality
3. Retention / Reaction Towers
The retention towers are used to provide retention time and temperature control for the pulp during the dispersing process.
Functions
-
Maintain pulp temperature
-
Provide reaction time for chemicals
-
Stabilize pulp flow before dispersing
Retention towers are commonly used in deinking systems and recycled pulp treatment lines.
