In the papermaking industry, the GD extraction roller refers to one
of the key equipment used for pulp clarification and concentration.
It is usually a rotating cylinder with tiny holes or grooves on the
surface.
The functions of the GD extraction roller are mainly as follows:
1. Clarifying pulp: When the pulp passes through the extraction
roller, moisture and smaller impurities are sucked out through the
holes, which helps to clarify the pulp and increase the solid
concentration in the pulp.
2. Concentrating pulp: The extraction roller reduces the moisture
content in the pulp by attracting moisture, thereby concentrating
the pulp. This helps to improve the quality and production
efficiency of paper.
3. Separating impurities: The holes on the surface of the roller
can filter out impurities in the pulp, such as small fibers,
impurity particles, etc., thereby improving the smoothness and
quality of the paper.
4. Adjusting the quality of pulp: The extraction roller can adjust
the pore size and layout of its surface as needed to adapt to the
production of different types and requirements of paper, such as
adjusting the thickness, glossiness and strength of the paper.
GD extraction roller plays a key role in the papermaking industry.
It helps improve the quality and production efficiency of pulp
through functions such as clarification, concentration and
separation. It is one of the indispensable equipment in the modern
papermaking process.
