Description

Technical Field

[0001] This application relates to the field of papermaking technology, specifically to a fan-shaped high-density disc grinding wheel. Background Technology

[0002] In the papermaking industry, grinding discs are components that use the mechanical action of the grinding disc teeth to process pulp fibers suspended in water, giving them the characteristics required for production on a papermaking machine and ensuring that the produced paper meets the expected quality requirements. The grinding discs are the "heart" of the pulp refiner, directly exerting shearing, crushing, stretching, and friction forces on the pulp fibers to change the fiber morphology and meet the requirements for papermaking adaptability.

[0003] Existing grinding discs are composed of a single unit or a group of individual grinding disc units. When a part of the grinding disc is damaged and needs to be replaced, the entire grinding disc needs to be disassembled, replaced, and installed. This operation is inconvenient, increases the labor intensity of workers, and reduces replacement efficiency. Therefore, a fan-shaped high-density disc grinding disc is needed. Utility Model Content
