Description
Technical field
The present invention relates to a kind of composite grinding ball for milling apparatus.
Background technology
Ball mill has widely at building materials metallurgy industries such as cement, silica flour preparations to be used, and improving pulverizing, mill efficiency, reducing the abrasive dust granularity is the target that the ball crusher design is pursued always.And the principal element that affects above-mentioned target is exactly the abrading-ball that uses in the ball crusher, and existing abrading-ball has two kinds of Metal Substrate antifriction alloy abrading-ball and nonmetal abrading-balls.In mechanical milling process, the metallic element of Metal Substrate antifriction alloy abrading-ball is easily sneaked into and is treated grind materials, and treat the purity of grind materials and bring very adverse influence, silicon powder for example, sneaking into of metallic element has a strong impact on its original use value; But not metal grinding ball hardness is high, wearability good, but lightweight, rolls material, grinding efficiency is low.
Summary of the invention
The object of the present invention is to provide a kind of composite grinding ball, easily sneak into material with the metallic element that solves existing Metal Substrate antifriction alloy abrading-ball, easily treat the purity of grind materials and bring adverse effect; But not the problem that metal grinding ball is lightweight, grinding efficiency is low.
In order to address the above problem, technical scheme of the present invention is:
A kind of composite grinding ball comprises the spherical shell that the metallic matrix piece that is arranged at the centre of sphere and parcel are fixed on described metallic matrix piece periphery, and described spherical shell is nonmetal spherical shell.
Described metallic matrix piece is integrally-built spheroidal metallic matrix piece, cylindricality metal matrix block, cone-shaped metal matrix block or rectangle metallic matrix piece, described spherical shell comprises the upper and lower spherical shell of Split type structure, the periphery of described upper and lower spherical shell has the upper and lower sphere that complementary kiss is joined, and the two ends of described metallic matrix piece are kissed respectively and joined secure bond in the inside of described upper and lower spherical shell.
Described metallic matrix piece is kissed join upper by split setting and complementation, lower billiard table piece docking forms, on, the interface of lower billiard table piece is a plane, the interface center of one of them billiard table piece is fixed with the connecting screw rod that center line is crossed the described composite grinding ball centre of sphere, the interface center of another billiard table piece is provided with the connecting screw hole with the corresponding setting of described connecting screw rod, on described, lower billiard table piece realizes that by described connecting screw rod and the threaded engagement of connecting screw hole its docking between the two is connected, described spherical shell comprises that split setting and identical being connected are incorporated on the correspondence, the upper spherical shell of lower billiard table piece periphery and lower spherical shell, described on, the periphery of lower spherical shell has complementary join upper of kissing, lower peripheral surface.
Described metallic matrix piece is cast iron metallic matrix piece.
Described spherical shell is corundum or ceramic nonmetal spherical shell.
Beneficial effect of the present invention is: the internal layer of composite grinding ball of the present invention is the metallic matrix piece, skin is nonmetal spherical shell, the metallic matrix piece has increased the weight of composite grinding ball, nonmetal spherical shell provides the wearability of composite grinding ball, by the synergy of metallic matrix piece and nonmetal spherical shell, compare with original Metal Substrate antifriction alloy abrading-ball and can prevent from mechanical milling process, treating pick-up metal element in the grind materials; Compare with nonmetal abrading-ball, improved abrading-ball weight, increased the grinding efficiency of abrading-ball.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention 1;
Fig. 2 is the figure that blows of Fig. 1.
Fig. 3 is the structural representation of the embodiment of the invention 2.
The specific embodiment
A kind of embodiment of composite grinding ball is shown in Fig. 1 ~ 2: comprise that being arranged at spheroidal metallic matrix piece and the bonding material of metallic matrix piece periphery that is fixed on of parcel that the centre of sphere and material are cast iron is the nonmetal spherical shell of pottery.Upper billiard table piece 2 and 4 docking of lower billiard table piece that the metallic matrix piece is joined by split setting and complementary kiss form, upper and lower billiard table piece is ball half, the interface 6 of upper and lower billiard table piece is a plane, interface 6 centers of lower billiard table piece 4 are fixed with the connecting screw rod 5 that center line is crossed the composite grinding ball centre of sphere, the interface center of upper billiard table piece 2 is provided with the connecting screw hole (not shown) with connecting screw rod 5 corresponding settings, and upper and lower billiard table piece realizes that by connecting screw rod 5 and the threaded engagement of connecting screw hole its docking between the two is connected.Nonmetal spherical shell comprises split setting and the upper spherical shell 1 and the lower spherical shell 3 that coincide and be connected and be incorporated into corresponding upper and lower billiard table piece periphery, and the periphery of upper and lower spherical shell has upper sphere 1-1 and the lower peripheral surface 3-1 that complementary kiss is joined.In other embodiments of the invention, the material of metallic matrix piece can also be replaced by metal materials such as lead, steel; The material of nonmetal spherical shell can also be replaced by wear-resistant materials such as corundum; It can also be 3: 7 or 4: 6 that upper and lower billiard table piece occupies whole metallic matrix block size ratio, and the size that accounts for whole nonmetal spherical shell of corresponding upper and lower spherical shell is and then corresponding change also.
Consist of by upper and lower two parts by metallic matrix piece and nonmetal spherical shell, make easy to process.Adopt the metallic matrix piece of cast iron quality to have larger weight, and the nonmetal spherical shell of ceramic material has namely improved the wearability of whole abrading-ball, also stops in mechanical milling process and treats pick-up metal element in the grind materials.Metal ball core matrix and nonmetal spherical shell synergy have improved whole grinding efficiency.
The embodiment 2 of composite grinding ball is as shown in Figure 3: the metallic matrix piece is integrally-built spheroidal metallic matrix piece 7 as different from Example 1.In other embodiments of the invention: spherical metal matrix block 7 can also be replaced by cylindricality metal matrix block, cone-shaped metal matrix block or rectangle metallic matrix piece.The coincide lower spherical shell of secure bond of 1 expression and upper half sphere of the spherical metal matrix block 7 upper spherical shell of secure bond that coincide among the figure, lower half sphere of 2 expressions and spherical metal matrix block 7.
