Abstract

The invention discloses a papermaking pulp mill with good milling effect, comprising a pulp mill upper housing, a pulp mill lower housing, a fixed millstone, a moving millstone, a driving mechanism, afeeding bucket, a plurality of support legs, and a discharge port. The lower end of the pulp mill upper housing is provided with the pulp mill lower housing; the pulp mill upper housing is releasablyconnected with the pulp mill lower housing; the pulp mill upper housing and the pulp mill lower housing fit each other while a milling chamber is arranged between them; the fixed millstone is arranged at the inner upper end of the milling chamber; the upper end of the fixed millstone is fixedly connected with the lower pulp mill upper housing; the lower end of the fixed millstone is provided withthe moving millstone that may cooperate with the fixed millstone. The fixed millstone and the moving millstone can cooperate to provide first milling for pulp; a lower conical millstone and a lower conical cavity can cooperate to provide second milling for the pulp; the pulp from double milling has higher fiber fineness and better quality.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of papermaking equipment, especially the technical field of pulp refiners. [0003] 【Background technique】 [0004] Paper is an important material, which is widely used in books, packaging and other fields, and is an important consumable. Papermaking is a very complicated process, mainly including two major processes: pulp making and papermaking. The pulping process usually includes: fiber raw material preparation, cooking pulping, slurry grinding, slurry screening, bleaching and other processes. There are a wide range of fiber raw materials commonly used in pulping, including: shrubs, branch wood, cotton stalks, hemp stalks, rice straw, reeds, etc. These raw materials are generally made by chemical pulping, mechanical pulping or semi-chemical mechanical pulping. pulp. In order to make the pulp fibers more refined, it is necessary to refine the pulp. The existing refiner refines the pulp unevenly,...
