In the paper making process, doctor blades are indispensable, core consumable components of the paper machine; they directly influence paper surface cleanliness, roll maintenance, and the continuous production efficiency of the entire machine. Leizhan’s doctor blades are compatible with production lines for various types of paper—including fine paper, printing paper, kraft paper, corrugated medium, and tissue—offering excellent wear resistance and consistent scraping performance.

Leizhan’s doctor blades are suitable for a wide range of applications, including dryer cylinders, press rolls, forming fabric sections, and coating units. Their primary function is to remove pulp, sizing agents, and contaminants adhering to roll and dryer surfaces, thereby preventing fiber buildup and reducing defects such as pinholes, spots, and sheet breaks to ensure high-quality paper formation.

Leizhan manufactures doctor blades designed for use with printing paper machines, tissue machines, and kraft paper machines. If your paper mill requires replacement doctor blades, please feel free to contact us via email for further information. Email address: pulperchina@gmail.com
