Abstract
The utility model relates to a composite grinding ball, which comprises a metal base block and a ball shell. The metal base block is disposed at the center of the ball, and the ball shell is fixedly connected to the periphery of the metal base block in a wrapping manner, and is a nonmetal ball shell. An inner layer of the composite grinding ball is the metal base block, an outer layer of the composite grinding ball is the nonmetal ball shell, the weight of the composite grinding ball is increased due to the metal base block, the composite grinding ball is abrasion-resistant due to the nonmetal ball shell, the metal base block and the nonmetal ball shell cooperate, accordingly, the composite grinding ball can prevent metal elements from being mixed into materials to be ground in a ball-milling process as compared with an original metal-base abrasion-resistant alloy grinding ball, the weight of the grinding ball is increased as compared with a nonmetal grinding ball, and the ball-milling efficiency of the grinding ball is enhanced.
Description
Technical field
The utility model relates to a kind of composite grinding ball that is used 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 influences 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 prone to sneak into treats grind materials, treat the purity of grind materials and bring very adverse influence, and 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 is good, but in light weight, rolls material, grinding efficiency is low.
The utility model content
The purpose of the utility model is to provide a kind of composite grinding ball, is prone to sneak into material with the metallic element that solves existing Metal Substrate antifriction alloy abrading-ball, treats the purity deleterious impact of grind materials easily; But not the problem that metal grinding ball is in light weight, grinding efficiency is low.
In order to address the above problem, the technical scheme of the utility model is:
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 said 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 branch body structure; The periphery of said 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 the inside of secure bond in said upper and lower spherical shell.
The upper and lower billiard table piece butt joint that described metallic matrix piece is joined by split setting and complementary kiss forms; The interface of upper and 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 said composite grinding ball centre of sphere; The interface center of another billiard table piece is provided with the connection screw with the corresponding setting of said connecting screw rod; Described upper and lower billiard table piece realizes that through said connecting screw rod and the threaded engagement that is connected screw its butt joint between the two is connected; Last spherical shell and following spherical shell that described spherical shell comprises the split setting and coincide and be connected and be incorporated into corresponding upper and lower billiard table piece periphery, the periphery of said upper and lower spherical shell have the upper and lower sphere that complementary kiss is joined.
Described metallic matrix piece is a cast iron metallic matrix piece.
Described spherical shell is corundum or ceramic nonmetal spherical shell.
The beneficial effect of the utility model is: the internal layer of the utility model composite grinding ball 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, through the synergy of metallic matrix piece and nonmetal spherical shell, compares with original Metal Substrate antifriction alloy abrading-ball and can prevent in mechanical milling process, to treat pick-up metal element in the grind materials; Compare with nonmetal abrading-ball, improved abrading-ball weight, increased the grinding efficiency of abrading-ball.

Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the figure that blows of Fig. 1.
Fig. 3 is the structural representation of the utility model embodiment 2.
The specific embodiment
The embodiment of composite grinding ball is shown in Fig. 1 ~ 2: comprise being arranged at the spheroidal metallic matrix piece and the bonding nonmetal spherical shell that is fixed on the material of metallic matrix piece periphery for pottery of parcel that the centre of sphere and material are cast iron.The last billiard table piece 2 that the metallic matrix piece is joined by split setting and complementary kiss forms with following billiard table piece 4 butt joints; 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 following 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 last billiard table piece 2 is provided with the connection screw (not shown) with connecting screw rod 5 corresponding settings, and upper and lower billiard table piece realizes that through connecting screw rod 5 and the threaded engagement that is connected screw its butt joint between the two is connected.Last spherical shell 1 and following spherical shell 3 that nonmetal spherical shell comprises the split setting and coincide and be connected and be incorporated into corresponding upper and lower billiard table piece periphery, the periphery of upper and lower spherical shell have last sphere 1-1 and the lower peripheral surface 3-1 that complementary kiss is joined.In other embodiment of the utility model, 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; The size that upper and lower billiard table piece occupies whole metallic matrix piece can also be 3: 7 or 4: 6, and the size that accounts for whole nonmetal spherical shell of corresponding upper and lower spherical shell is also and then corresponding to be changed.
Constitute by upper and lower two parts through metallic matrix piece and nonmetal spherical shell, fabrication and processing is convenient.Adopt the metallic matrix piece of cast iron quality to have bigger weight, and the nonmetal spherical shell of ceramic material has promptly improved the wearability of whole abrading-ball, in mechanical milling process, also stops 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: different with embodiment 1 is that the metallic matrix piece is integrally-built spheroidal metallic matrix piece 7.In other embodiment of the utility model: spherical metal matrix block 7 can also be replaced by cylindricality metal matrix block, cone-shaped metal matrix block or rectangle metallic matrix piece.1 expression and last half sphere of spherical metal matrix block 7 the last spherical shell of secure bond that coincide among the figure, the following spherical shell of the identical secure bond of following half sphere of 3 expressions and spherical metal matrix block 7.
