Kraft Paper Recycle Production Line

KRAFT PAPER RECYCLE PRODUCTION LINE

Kraft paper recycle production line is designed to turn used kraft paper into reusable materials. Here are its main components and processes:

1.Sorting and Preparation

- Sorting: First, the collected used kraft paper is sorted to remove any contaminants like plastics, metals, and other non-paper substances. This ensures the purity of the raw material for the recycling process.

- Shredding: The sorted kraft paper is then shredded into smaller pieces. This increases the surface area, making it easier for subsequent processing steps.

Pulping

- The shredded kraft paper is mixed with water and chemicals in a pulping machine. The chemicals help to break down the fibers and remove any ink or impurities still remaining on the paper. This results in a pulp slurry.

Screening and Cleaning

- Screening: The pulp slurry is passed through screens to remove any remaining large particles or debris that were not removed during the sorting and pulping steps.

- Cleaning: It is then further cleaned using centrifugal cleaners or other devices to separate out any fine impurities like sand or small pieces of plastic that might have remained.

Refining

- The cleaned pulp is sent to a refiner where the fibers are further processed to improve their quality. This helps in enhancing the strength and smoothness of the recycled kraft paper that will be produced.

Papermaking

- The refined pulp is then formed into a continuous sheet of paper on a paper machine. This involves processes like forming the pulp on a wire mesh, pressing to remove excess water, and drying to get the final kraft paper product.

Finishing

- The dried kraft paper may go through finishing processes such as calendering to improve its surface smoothness and appearance. It can also be cut and rolled into the desired sizes for further use in packaging or other applications.

Overall, a kraft paper recycle production line plays an important role in reducing waste and conserving resources by giving new life to used kraft paper.
