AI Technical Summary
The existing grinding discs suffer from low material utilization, short lifespan, and uneven slurry distribution, resulting in uneven grinding slurry quality and equipment vibration. Furthermore, the fine grinding teeth are difficult to form and are prone to breakage during use.
The grinding discs of the refining machine adopt a bridge structure, with the grinding tooth assembly and the substrate designed separately. The substrate is made of ordinary steel, while the grinding tooth part is made of high-quality wear-resistant material. Compensation channels are set on the grinding discs to balance the distribution of slurry and extend the service life.
It significantly reduces manufacturing costs, extends the service life of grinding discs, improves the uniformity and efficiency of grinding pulp quality, and realizes the integration of grinding and screening.
