Description
Technical field
The present invention relates to a kind of for the composite grinding ball in milling apparatus.
Background technology
Ball mill the building materials metallurgy industry such as to be prepared at cement, silica flour and is had a wide range of applications, and improves pulverizings, target that mill efficiency, reduction abrasive dust granularity are ball crusher design pursuit always.And the principal element affecting above-mentioned target is exactly the abrading-ball used in ball crusher, existing abrading-ball has Metal Substrate antifriction alloy abrading-ball and nonmetal abrading-ball two kinds.In mechanical milling process, the metallic element of Metal Substrate antifriction alloy abrading-ball is easily mixed into treats grind materials, and the purity treating grind materials brings very adverse influence, such as silicon powder, and being mixed 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, roll material, grinding efficiency is low.
Summary of the invention
The object of the present invention is to provide a kind of composite grinding ball, be easily mixed into material with the metallic element solving existing Metal Substrate antifriction alloy abrading-ball, the purity easily treating grind materials brings adverse effect; But not the problem that metal grinding ball is lightweight, grinding efficiency is low.
In order to solve the problem, technical scheme of the present invention is:
A kind of composite grinding ball, comprise the spherical shell that the metallic matrix block that is arranged at the centre of sphere and parcel are fixed on described metallic matrix block periphery, described spherical shell is nonmetal spherical shell.
Described metallic matrix block is integrally-built spheroidal metallic matrix block, cylindricality metal matrix block, cone-shaped metal matrix block or rectangle metallic matrix block, described spherical shell comprises the upper and lower spherical shell of Split type structure, the periphery of described upper and lower spherical shell has complementation and kisses the upper and lower sphere of joining, and the two ends of described metallic matrix block are kissed respectively and joined secure bond in the inside of described upper and lower spherical shell.
Described metallic matrix block arranged by split and complementary kiss join upper, lower billiard table block docking forms, on, the interface of lower billiard table block is a plane, the interface center of one of them billiard table block is fixed with the connecting screw rod that center line crosses the described composite grinding ball centre of sphere, the interface center of another billiard table block is provided with the connecting screw hole that arrange corresponding to described connecting screw rod, described is upper, lower billiard table block realizes its docking between the two by described connecting screw rod and the threaded engagement of connecting screw hole and is connected, described spherical shell comprises split and arranges and coincide to be connected and be incorporated in correspondence, the upper spherical shell of lower billiard table block periphery and lower spherical shell, on described, it is upper that the periphery of lower spherical shell has that complementary kiss joins, lower peripheral surface.
Described metallic matrix block is iron metal matrix block.
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 metallic matrix block, skin is nonmetal spherical shell, metallic matrix block adds the weight of composite grinding ball, nonmetal spherical shell provides the wearability of composite grinding ball, by the synergy of metallic matrix block and nonmetal spherical shell, can prevent from treating to be mixed into metallic element in grind materials in mechanical milling process compared with original Metal Substrate antifriction alloy abrading-ball; Compared with nonmetal abrading-ball, improve abrading-ball weight, add the grinding efficiency of abrading-ball.

Detailed description of the invention
A kind of embodiment of composite grinding ball is as shown in Figure 1 and 2: comprise and be arranged at the centre of sphere and material is the spheroidal metallic matrix block of cast iron and the bonding material being fixed on metallic matrix block periphery of parcel is the nonmetal spherical shell of pottery.Metallic matrix block is arranged by split and complementary kisses the upper billiard table block 2 of joining and the docking of lower billiard table block 4 forms, upper and lower billiard table block is half ball, the interface 6 of upper and lower billiard table block is a plane, interface 6 center of lower billiard table block 4 is fixed with the connecting screw rod 5 that center line crosses the composite grinding ball centre of sphere, the interface center of upper billiard table block 2 is provided with the connecting screw hole (not shown) that arrange corresponding to connecting screw rod 5, and upper and lower billiard table block realizes its docking between the two by connecting screw rod 5 and the threaded engagement of connecting screw hole and is connected.Nonmetal spherical shell comprises split and arranges and the coincide upper spherical shell 1 and lower spherical shell 3 that are connected and are incorporated into corresponding upper and lower billiard table block periphery, and the periphery of upper and lower spherical shell has complementation and kisses the upper sphere 1-1 and lower peripheral surface 3-1 that join.In other embodiments of the invention, the material of metallic matrix block 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 block occupies whole metallic matrix block can also be 3: 7 or 4: 6, and the size accounting for whole nonmetal spherical shell of corresponding upper and lower spherical shell is also and then corresponding to be changed.
Formed by upper and lower two parts by metallic matrix block and nonmetal spherical shell, make easy to process.Adopt the metallic matrix block of cast iron quality to have larger weight, and namely the nonmetal spherical shell of ceramic material improve the wearability of whole abrading-ball, also stops and treat to be mixed into metallic element in grind materials in mechanical milling process.Metal ball core matrix and nonmetal spherical shell act synergistically and improve whole grinding efficiency.
The embodiment 2 of composite grinding ball is as shown in Figure 3: metallic matrix block is integrally-built spheroidal metallic matrix block 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 block.The 1 upper spherical shell representing secure bond of coincideing with upper half sphere of spherical metal matrix block 7 in figure, the 2 lower spherical shells representing secure bond of coincideing with lower half sphere of spherical metal matrix block 7.
