Description

Technical Field

[0001] This utility model relates to the field of disc mill technology, and more specifically, to pulp disc milling equipment for kraft paper production. Background Technology

[0002] Disc mills are used in the production of kraft paper. A disc mill is a high-efficiency, heavy-duty crushing and grinding device widely used in industries such as papermaking, chemicals, food, and mineral processing. It uses the powerful shearing force, friction, and pressure generated between two relatively rotating grinding discs (usually made of steel or hard alloy) to finely crush, mix, or disperse materials entering the disc. Disc mills not only feature large processing capacity, low energy consumption, and uniform and fine crushing effect, but also allow for flexible control of particle size distribution by adjusting parameters such as the disc gap and rotation speed to meet different process requirements. With its compact design, robust structure, and ability to operate continuously, it is an indispensable key piece of equipment in modern industrial production.

[0003] The two grinding discs inside a disc mill are a fixed disc and a moving disc. Most existing mills adjust the position of the moving disc to adjust the gap between the two discs. However, adjusting the position of the moving disc also changes the gap between the moving disc and the inner wall of the grinding chamber. An excessively large gap may lead to uneven distribution of the slurry between the discs, affecting slurry flow and thus the quality of the pulping process; an excessively small gap may increase friction and wear between the disc and the outer casing, reducing the lifespan of the equipment. Utility Model Content
