Embodiment 1

[0081] The present invention provides a bowl grinder as described above, wherein the mortar is made of corundum with a purity of 99%. The radius of the hammer head 211 is R 1 , The radius of the semicircular bottom of the circular orbit 102 is R 2 , R 2 -R 1 =0.5mm. When the spherical hammer head 211 is ground in the annular track 102, the gap between the semicircular inner surface of the bottom of the annular track 102 and the lower half spherical surface of the hammer head 211 is filled with material. The above mortar has a relatively large volume and can be used to grind 50 grams of materials.

Embodiment 2

[0083] The present invention provides a bowl grinder as described above, wherein the mortar is made of wear-resistant ceramics. The radius of the hammer head 211 is R 1 , The radius of the semicircular bottom of the circular orbit 102 is R 2 , R 2 -R 1 =0.01mm. When the spherical hammer head 211 is ground in the annular track 102, the gap between the semicircular inner surface of the bottom of the annular track 102 and the lower half spherical surface of the hammer head 211 is filled with material. The above mortar has a relatively large volume and can be used to grind 50 grams of materials.

Embodiment 3

[0085] The present invention provides a bowl grinder as described above, wherein the mortar is made of corundum with a purity of 99%. The radius of the hammer head 211 is R 1 , The radius of the semicircular bottom of the circular orbit 102 is R 2 , R 2 -R 1 =0.2mm. When the spherical hammer head 211 is ground in the annular track 102, the gap between the inner surface of the bottom of the annular track 102 and the lower half spherical surface of the hammer head 211 is filled with materials.

[0086] The bowl grinder provided in Examples 1-3 of the present invention was used to grind calcium carbonate, and the grinding results are shown in Table 1.

[0087] Table 1 Grinding effect data of Examples 1 to 3

[0088]

[0089] According to the data in Table 1, compared with the existing manual mortar and motorized grinder, the bowl grinder provided by the present invention has higher grinding efficiency, and the bowl grinder of the present application can perform fine grinding. Grinding...

Abstract

The invention relates to grinder improvement, and concretely relates to a mortar grinder to solve the ultrahigh purity grinding requirement and the defects of low efficiency, insufficient grinding fineness and very low yield of present manual mortars. The mortar grinder comprises a speed reducer, a mortar shaft, mortar shaft bodies, a toothed ring, a grinding lever arm, pinion shafts, pinions, elastic connectors, a mortar body, an adjusting seat, a baseboard and columns. The mortar grinder can reach a fine grinding and crushing requirement, has a high grinding efficiency and realizes fine granularity. The materials of the mortar body and a mortar hammer contained by the mortar body are wear resistant materials, such as corundum and other ceramic materials. The mortar grinder can be used for low temperature grinding, can realize wet or dry grinding, and makes impurity interfusion or deterioration of a grinding material not appear.

Description

Technical field [0001] The invention relates to an improvement of a grinder, in particular to a bowl grinder. Background technique [0002] The grinder is a kind of pulverizer. It is a machine that pulverizes large-size solid raw materials to the required size. At present, some grinders usually have one or more pulverization chambers, and the pulverization chamber is relatively large to grind and crush large amounts of materials. However, there are few grinders used to grind small amounts of materials, and it is difficult to achieve high-precision pulverization. Because the materials are all metals, impurities and contaminants often appear, or the heat generated during the grinding process causes grinding The material has deteriorated. Summary of the invention [0003] In order to solve the requirements of ultra-high purity grinding and the defects of the existing manual mortars such as low efficiency, insufficient fine grinding degree and low yield, the present invention provide...
