Abstract
The utility model discloses a regular dodecahedron grinding body of a ball mill. The outer surface of the grinding body is a sealed regular dodecahedron consisting of twelve regular pentagons, the edge of each regular pentagon is coincided with the edges of five regular pentagons which are adjacent with the regular pentagon, and the edge of the regular pentagon is 10mm. The grinding body disclosed by the utility model is a regular dodecahedron spherical grinding body, when the two grinding bodies are ground, the comprehensive contact friction among points, lines and surfaces exist, so that the output of the ball mill and the grinding fineness are improved, and then the grinding efficiency is improved. In addition, the ratio of the area to the weight of the grinding body is high, and then, the economic benefit is improved, and the consumption of mineral resources is reduced.
Description
Technical field
The utility model relates to the ball mill for the grinding technology field such as mine, cement plant, thermal power plant, relates in particular to a kind of regular dodecahedron ball mill grinding body.
Background technology
Current, the ball mill grinding body has following shortcoming take spheroid and cylinder as main:
1, only have a few and contacting of putting, or the contact of very small face, therefore grinding efficiency is low;
2, effectively milling area and weight ratio are low;
3, economic benefit is low, and is larger to the consumption of mineral resources.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of effective increase contact area and a kind of regular dodecahedron ball mill grinding body of the comprehensive contact friction of point, line, surface is arranged.For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of regular dodecahedron ball mill grinding body, described abrasive body outer surface is the regular dodecahedron of a sealing that is comprised of 12 regular pentagons, the seamed edge of the seamed edge of each regular pentagon and five regular pentagons adjacent with this regular pentagon overlaps, and the seamed edge of described regular pentagon is long is 10mm.
Preferably, described abrasive body is a solid abrasive body.
Preferably, described abrasive body is a hollow abrasive body.
A kind of regular dodecahedron ball mill grinding body that the utility model relates to, two abrasive bodies have the comprehensive contact friction between point, line, surface when grinding, thereby improve output and the grinding fineness of ball mill, and then improve grinding efficiency.In addition, the area weight of this abrasive body is than high, and then improved economic benefit, reduced the consumption to mineral resources.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model grinding state.
The specific embodiment
Further illustrate embodiment of the present utility model below in conjunction with accompanying drawing.
See Fig. 1, a kind of regular dodecahedron ball mill grinding body that the utility model relates to, described abrasive body 1 outer surface is the regular dodecahedron of a sealing that is comprised of 12 regular pentagons 2, the seamed edge of the seamed edge of each regular pentagon 2 and five regular pentagons 2 adjacent with this regular pentagon 2 overlaps, the seamed edge of described regular pentagon 2 is long is 10mm, and the area of each regular pentagon 2 is 172mm
2, the surface area of this abrasive body 1 is 2064mm
2, volume is 7663mm
3
Preferably, described abrasive body 1 is a solid abrasive body, and the quality of solid abrasive body is larger, and larger impact value is arranged during the whereabouts, helps to grind, and can keep the grainding capacity of long period simultaneously.
Preferably, described abrasive body 1 is a hollow abrasive body, make hollow abrasive body and both can save the production material, can effectively avoid the abrasive body later stage not only not have abrasive action again, can occupy on the contrary the problem in effective grinding space of ball mill, decide according to the size of effective lapping diameter of grinding body gradation and abrasive body, the hollow size of hollow abrasive body does not wait from 3-150mm.
The production material of described abrasive body 1 can be the materials such as plain cast iron, cast steel, steel rolling, chrome alloy cast iron, high chrome, potassium steel, chrome-moly steel, form omnibearing grinding system by point, line, surface and replace the principle that traditional spheroid or cylindrical wear-resistant ball only grind to select contact or small contact tangent plane, see Fig. 2, improved greatly grinding efficiency.In addition, the abrasive body of this regular dodecahedron has the symmetry of any direction of spheroid, and every seamed edge, each angle, each face has uniformity, when making the ball mill running, no matter abrasive body with what attitude falls or friction all can be ground uniformly.
Now illustrate this regular dodecahedron abrasive body and traditional spheroid, the difference of cylinder abrasive body.the volume of supposing regular dodecahedron, spheroid and cylinder (according to the existing product actual conditions, the ratio of cylindrical height and diameter being decided to be 5:4) is all 20, by cubature formula V ball=20=4/3 π r3, and the r ≈ 1.684 of ball, F ball=4 π r 2 ≈ 35.61, by the positive 12=20=7.6631a3 of cubature formula V, a ≈ 1.684 that asks, the positive 12=20.6457a2 ≈ 39.18 of F, V ball=20=π r 2h, obtain r=1.3665, h=3.414, F cylinder=33.02, F is body surface area, calculate F positive 12 this moment and go out greatly approximately 10% than F ball, F positive 12 is than F cylinder general goal approximately 11.9%, illustrating that F positive 12 is bright has a larger surface area, the area of each face of regular dodecahedron is about 3.265, through actual measurement, the actual contact diameter that effectively grinds of spheroid is about 1/8 of its maximum gauge, so its effective milling area only 0.1392, cylinder because on the reason of going to the bottom, its contact-making surface can be large more many than ball, but the situation that is all at every turn the face contact is little more a lot of than regular dodecahedron, no matter and regular dodecahedron is with point or rib contact, through sliding, finally can become contacting of face and face, so effective milling area of regular dodecahedron is exactly the area of one face, effective milling area of learning the regular dodecahedron abrasive body is 23.47 times of effective milling area of ball lapping body, and effective milling area of regular dodecahedron abrasive body is also far above effective milling area of cylinder abrasive body, therefore greatly improved its grinding efficiency.
