Paper mill is the core component of Pulping mill in papermaking industry. It belongs to vulnerable parts, and its Service life affects the quality of pulp and paper quality and production Efficiency directly.

Refined cooking or mechanical abrasion, Sifting and bleaching of pulp after bleaching, can not be used directly to copy Paper. Because of the pulp fiber is lack of flexibility, the adhesion strength of the fiber and the fiber is not ideal enough, if use it to writing, the paper Will be porous, rough surface, the strength is low, cannot satisfy the Requirement of use. the mill is the heart of the pulping machine, which directly Produces shear, crushing, stretching, friction and other forces to change the Shape of the fiber and satisfy the adaption.
