Description

Grinding disc for crushing paper pulp raw materials and primary pulp anti-overflow device

Technical Field

The invention relates to the technical field of pulping machines, in particular to a grinding disc for crushing a paper pulp raw material and a primary pulp anti-overflow device.

Background

Pulping is an essential process for papermaking, and the quality of pulping directly influences the strength of paper products and the binding force of fibers.

The fluidity of the pulp is weak when the fiber in the pulp is long, and the pulp is inconvenient to flow out of the millstone at the moment, so that the grinding work can not be carried out quickly. During the grinding process, the pulp can gradually approach the edge of the upper grinder and the edge of the lower grinder along with the rotation of the upper grinder and overflow from the edges of the two grinding discs, thereby not only wasting the pulp but also damaging the environment.
