[0026] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0027] like Figure 1-5 As shown, this utility model provides a grinding mill, including a grinding cup 2. A stirring assembly is horizontally rotatable inside the grinding cup 2. The stirring assembly is driven to rotate by a driving assembly. A grinding assembly is connected to the stirring assembly. A grinding groove 14 or a grinding protrusion (not shown in the figure) is provided on the inner side wall of the grinding cup 2. A grinding gap is formed between the grinding assembly and the grinding groove 14 or the grinding protrusion.

[0028] The stirring component rotates horizontally inside the grinding cup, driving the grinding component to rotate horizontally as well. The grinding gap between the grinding component and the grinding groove 14 or grinding protrusion forms a grinding surface for the material. The concave and convex stripes on the surface of the grinding groove 14 or grinding protrusion effectively increase the friction area for grinding the material, which is beneficial to improving the grinding effect, thereby shortening the grinding time and avoiding the problem of powder easily dissolving and sticking due to excessive grinding temperature, as well as the problem of powder settling at the bottom of the grinding cup after repeated stirring and burning.

[0029] Furthermore, the inner wall of the grinding cup 2 is provided with a powder outlet 7, and a filter screen 6 is detachably provided on the inlet end of the powder outlet 7. The height of the powder outlet 7 is the same as the height of the grinding assembly. Under the drive of the stirring assembly, the grinding assembly realizes simultaneous stirring and grinding. The material is squeezed and ground through the gap between the grinding assembly and the grinding groove 14 or the grinding protrusion, and the material is stirred. During the grinding process, powder with a fineness that reaches the size of the filter screen 6 can be discharged from the mesh of the filter screen 6 in time, avoiding the problem of powder deposition and burning.

[0030] Furthermore, the filter screen 6 includes a mesh structure with various mesh sizes, and the pore size of the filter screen 6 ranges from 16 to 50 mesh, which can be used to grind materials with different fineness requirements, thereby realizing the adjustment of the grinding fineness of the grinding mill.

[0031] Furthermore, the stirring assembly includes a stirring shaft 5 and a cross-shaped frame 3 mounted on the stirring shaft 5. The upper end of the stirring shaft 5 is fixedly connected to the center of the cross-shaped frame 3, and the stirring shaft 5 is perpendicular to the cross-shaped frame 3. The grinding assembly is a square column 4. Each end of the cross-shaped frame 3 is connected to a square column 4. The columnar surface of the square column 4 forms a corresponding grinding surface with the inner grinding groove 14 or grinding protrusion of the grinding cup 2, effectively increasing the grinding area and enabling the grinding material to be quickly refined. The combination of the cross-shaped frame 3 and the square column 4 enables rapid stirring and grinding, driving the material to be ground quickly and discharged from the filter screen 6 in a timely manner, effectively improving the grinding effect and powder output efficiency.

[0032] Furthermore, the grinding groove 14 or grinding protrusion is spirally shaped, which can effectively increase the grinding area of ​​the material and improve the grinding efficiency.

[0033] Furthermore, a drive assembly is provided below the grinding cup 2. The drive assembly includes a base 13, a housing 11, and a motor 12. The housing 11 is mounted on the base 13, and the motor 12 is located inside the housing 11. The output shaft of the motor 12 is connected to the stirring shaft 5.

[0034] Furthermore, the grinding cup 2 is provided with a cup lid 1, and a connecting cavity 15 is formed at the bottom of the grinding cup 2. A through hole is provided at the bottom of the grinding cup 2, and the lower end of the stirring shaft 5 extends through the through hole into the connecting cavity 15. A connecting assembly is provided in the connecting cavity 15. The connecting assembly includes an upper connector 9 and a lower connector 10. The upper connector 9 is threadedly connected to the lower end of the stirring shaft 5, and the lower connector 10 is threadedly connected to the upper end of the output shaft of the motor 12. The upper connector 9 and the lower connector 10 are snap-fitted together, realizing the transmission connection between the motor 12 and the stirring shaft 5. Through the setting of the upper connector 9, the stirring assembly can be detachably connected, and stirring assemblies of different radii can be replaced, which is conducive to adjusting different grinding gaps, thereby obtaining different fineness of grinding materials.

[0035] Furthermore, a bearing mounting seat is fixedly provided below the through hole, and two ball bearings 8 are provided inside the bearing mounting seat. The ball bearings 8 are sleeved on the stirring shaft 5, which can reduce frictional loss during the rotation of the stirring shaft 5 and improve the grinding stability.

[0036] Furthermore, the grinding gap formed between the grinding component and the grinding groove 14 or the grinding protrusion is 8mm-12mm. This grinding mill can select stirring components of different radii according to different material grinding fineness requirements, so that different grinding gaps are formed between the grinding component and the grinding groove 14 or the grinding protrusion, which is conducive to efficient grinding and realizes the adjustment of grinding fineness.

[0037] When using the grinding mill described in this utility model, different combinations of filter screens 6 with different pore sizes and stirring components with different radii are selected according to different materials. The filter screen 6 is installed at the inlet end of the powder outlet 7. The lower end of the stirring shaft 5 extends downward through the through hole at the bottom of the grinding cup 2 and the ball bearing 8. The upper connector 9 is threadedly connected to the lower end of the stirring shaft 5. The grinding cup 2 is snapped onto the drive component. The upper connector 9 and the lower connector 10 are snapped together. The material to be ground is put into the grinding cup 2, the power is turned on, and the grinding operation begins. During the grinding process, the powder in the grinding cup that reaches the pore size of the filter screen 6 will be discharged from the powder outlet 7 in a timely manner, resulting in high powder discharge efficiency and effectively avoiding the problem of powder deposition and burning.
