In the papermaking industry, the round wire cylinder, commonly
known as the cylindrical screen or cylinder mold, plays a pivotal
role in the processing of pulp.
Description:
The round wire cylinder typically consists of a cylindrical mesh
structure with varying mesh sizes to accommodate different types of
pulp. It is shaped as a horizontal or inclined cylinder with a fine
mesh on its inner surface.
Function:
- Dewatering: During papermaking, pulp enters the cylinder through the headbox
of the paper machine. As the cylinder rotates, water in the pulp
passes through the mesh, facilitating the formation of wet paper
sheets.
- Screening: The cylinder mold also serves to remove impurities from the pulp,
such as fiber clumps and insoluble particles, ensuring the quality
and uniformity of the final paper.
- Sheet Formation: The pulp, after dewatering through the cylinder mold, gradually
forms into wet paper sheets. Subsequent pressing and drying
processes transform these into dry paper sheets.
In summary, the round wire cylinder plays a critical role in the
papermaking industry by efficiently dewatering pulp, screening out
impurities, and contributing to the quality and production
efficiency of paper.
