Description

Technical Field

[0001] The utility model relates to the technical field of grinding discs, in particular to a cubic boron nitride grinding disc with a discharge structure. Background Art

[0002] A stone mill is a machine used to process rice, wheat, beans and other grains into powder or pulp. A traditional stone mill is usually made of two round stones, namely an upper mill and a lower mill. The joints of the upper mill and the lower mill have textures, i.e., grinding teeth. Grains enter the middle of the upper mill and the lower mill from the feeding hole of the upper mill, move outward along the grinding teeth, and are ground to form powder when rolling over the two surfaces. Announcement No.: CN203316182U discloses a grinding disc, including an upper disc and a lower disc. The upper grinding surface of the upper disc overlaps and contacts with the lower grinding surface of the lower disc to form a grinding chamber, and a connecting shaft is provided between the upper disc and the lower disc. The lower disc is in the shape of a frustum with a small top and a large bottom. The upper disc is in the shape of a frustum with a large top and a small bottom. The longitudinal section of the outer annular surface of the upper disc and the longitudinal section contour line of the outer annular surface of the lower disc are convex curves. The lower disc is installed in the grinding bucket. Since the lower disc of the grinding disc is designed to be in the shape of a frustum with a small top and a large bottom, the slurry during grinding can slowly flow into the grinding bucket along the inclined surface of the frustum to prevent liquid splashing. At the same time, the upper plate of the grinding disc is designed to be a cone shape with a large top and a small bottom, which can prevent the ground slurry from sticking to the upper plate when grinding sticky materials. However, during the use of the above technology, the materials generated during the grinding process will accumulate in the grinding bucket, and the materials will flow out of the discharge chute relatively slowly. A large amount of materials will accumulate inside the grinding bucket, which will affect the grinding efficiency. After the grinding work is completed, the aggregates in the grinding bucket need to be cleaned with the help of tools, which increases the workload, so it needs to be improved. Utility Model Content
