The doctor holders are commonly applied in pulp filtration and paper refinement processes. During the pulp filtration process, when the pulp passes through the mesh surface, the doctor holder contacts the mesh surface and applies appropriate pressure to remove liquid and impurities in the pulp. The principle of the doctor holder is based on the friction and pressure between the doctor holder and the mesh surface.

First of all, the doctor holder has a simple structure and is easy to install and maintain. Secondly, the doctor blade material of the doctor holder has been specially treated to be wear-resistant and corrosion-resistant, extending the service life of the doctor holder. In addition, the doctor holder also has the function of adjusting the pressure and angle of doctor blade to meet different paper types and process requirements.
