Problems solved by technology

Most of the existing disc refiners are only suitable for working with medium and low-grade slurries. When working with high-concentration feed disc grinders, clogging often occurs, the machine runs unstable, and the type of disc grinder has poor adaptability; The grinding and dispersing effect of fiber bundles is poor, and the efficiency of brushing and splitting is low, so it is not suitable for grinding and impregnating equipment at the same time, so there is no room for simplifying the composition of the existing pulping system

Abstract

The invention provides a high-milling type mill disk which is composed of a fixed mill disk and a movable mill disk of which the disk surfaces are matched with each other, wherein the disk surfaces of the two mill disks are correspondingly provided with a separation mill region, a dispersion mill region and a fine mill region from inside to outside; the dispersion mill region is a multi-concentric-toothed-ring arrangement region in which the two mill disks mesh with each other; and each toothed ring is evenly provided with a plurality of material channels. The invention also provides a high-milling type impregnating disk mill using the high-milling type mill disk. By using the technical scheme, pulp fiber bundles, including thin fiber bundles, can be dispersed and refined in a better way, thereby completely adapting to milling operation of various high / medium-concentration (10-35%) materials; the fiber abrasion is small; and the technical scheme provides a large compression space for shortening the composition of a mechanical pulp / chemimechanical pulp making system.

Description

technical field [0001] The application of the present invention relates to disc refining and pulping equipment using natural fibrous plants as raw materials. The fiber bundles are opened by rotating the disc to achieve a comprehensive fine fiber effect. Background technique [0002] The disc refiner is an important equipment in the mechanical pulp or chemical mechanical pulp pulping system. Its main structure is as follows: the fixed and movable discs face opposite to each other and are installed in the disc refiner with a flat grinding gap. The central opening of the grinding disc leads into the disc grinding chamber, and the movable grinding disc is fixed on the shaft end of the main shaft penetrating into the disc grinding chamber. Most of the existing disc refiners are only suitable for working with medium and low-grade slurries. When working with high-concentration feed disc grinders, clogging often occurs, the machine runs unstable, and the type of disc grinder has poo...
