Paper Machine Roll For GD Extraction Roller

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.
