The calender mainly consists of several rollers, typically made of metal or other special materials, which rotate in coordination with each other at a certain pressure and speed. When paper passes through the gaps between the rollers, under the action of pressure and friction, the fibers on the paper surface are further compacted and aligned, thereby improving the paper’s smoothness, gloss, and density.

 

For paper mills, the importance of calenders is self-evident. In today’s market, where the requirements for paper quality are increasingly stringent, high-quality paper not only needs good physical properties such as strength and toughness but also excellent appearance. Calenders refine the paper surface, making it smoother and flatter, reducing microscopic undulations and roughness, thereby improving the paper’s printability. During the printing process, a smooth paper surface better absorbs ink, resulting in clearer, more vibrant printed images and higher color fidelity, significantly improving the quality and visual effect of printed materials.

 

Choosing the appropriate type of calender and high-quality spare parts is crucial for ensuring smooth production and improving paper quality. With the development of the industry, calenders will continue to innovate and progress, injecting new vitality into the paper industry.
