The working principle of the Doctor Blade is based on the friction between the Doctor Blade and the screen. The part where the Doctor Blade contacts the screen forms a narrow gap. When the pulp passes through this gap, the Doctor Blade will scrape off the excess pulp. The Doctor Blades are widely applied, not only in paper production, but also play an important role in coating and printing fields.

The Doctor Blade is usually made of high-quality steel, which has high strength and hardness and can withstand greater pressure and friction. Its material and surface are specially treated to be wear-resistant and extend its service life. The angle and pressure of the Doctor Blade can be adjusted and controlled according to actual needs to adapt to the requirements of different papers.
