Paper Pulp Separator Description :

The Paper Pulp Separator is a core piece of equipment in papermaking and waste paper recycling processes. Its primary function is to efficiently separate various impurities (such as fiber bundles, plastic fragments, metal particles, sand, residual ink, etc.) from paper pulp, purifying the pulp to provide high-quality raw materials for subsequent paper production. It is a key link in ensuring paper quality and improving production efficiency.

Paper Pulp Separator Function :

During the pulping process (e.g., after waste paper is processed by a pulper), a large amount of undispersed fiber clumps and non-fibrous impurities (such as strapping tapes, adhesives, dust, etc.) are mixed into the pulp. The Paper Pulp Separator separates these impurities from qualified pulp through physical screening, centrifugal separation, and other methods, ensuring the pulp meets the required cleanliness and uniformity for production.

Paper Pulp Separator Structure and Principle:

This paper pulp separator machine consists of three parts

1. Shell:

It consists of upper and lower parts composed of structural parts. The upper shell is equipped with an adjustable angle guide plate, a ￠6MM water spray hole and a reverse wear-resistant plate; the lower shell is equipped with a semicircular sieve plate. During maintenance, the upper shell can be manually turned 90° by a screw device to facilitate inspection and replacement of internal accessories.

2. Rotor:

There is a high-speed rotating rotor between the upper and lower shells. During operation, the stirring blades and blades will impact the incoming tail slurry multiple times to separate the fibers from the slurry. Under the washing of flushing water, the fibers pass through the following The screen plate leaks into the outlet slot, and the waste materials are pushed to the waste outlet one by one. It is normal for waste materials to contain no fiber. The distance between the blade on the rotor and the sieve plate below should be strictly controlled between 0.5-1.5MM. If the gap exceeds 2MM, the deterioration of the sorting effect will cause the sieve plate to be blocked and the fiber content of the waste outlet will increase. At this time, the blade or screen plate should be replaced to ensure that the gap is within the required range. When replacing the blade, the corresponding weight of the blade must be strictly controlled to ensure the balance accuracy of the rotor when rotating at high speed. Otherwise, vibration will occur, endangering the safety of people and buildings. It is recommended to correct the balance of the rotor when overhauling or completely replacing the blades. The balance grade is G6.3.

3. Guide plate and water spray hole:

The angle and direction of the guide plate should be adjusted according to the impurity content in the tail slurry to adapt to the washing time of the impurities in the machine and ensure that the waste does not contain fiber. The water spray holes should be checked frequently to ensure normal water supply and should not be interrupted during operation to prevent blockage from affecting the sorting effect.

Paper Pulp Separator Advantages :

1.Improves Pulp Quality: Effectively removes impurities, reduces spots and holes in finished paper, and enhances paper strength, whiteness, and smoothness.

2.Protects Subsequent Equipment: Prevents hard impurities (such as metals and sand) from entering paper machines, reducing equipment wear and extending the service life of the production line.

3.Enhances Production Efficiency: Automated separation reduces manual screening costs, while stable pulp quality lowers the probability of failures in subsequent processes.

4.Facilitates Eco-Friendly Recycling: In waste paper recycling processes, efficient impurity separation increases waste paper utilization, reduces virgin wood consumption, and aligns with circular economy needs.

5.Strong Adaptability: Can adjust parameters according to pulp types (e.g., wood pulp, straw pulp, waste paper pulp) and impurity characteristics, adapting to different paper production needs (such as high-grade paper, packaging paper, toilet paper, etc.).
