Embodiment Construction

[0014] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] See figure 1 , a dodecahedron ball mill grinding body that the present invention relates to, the outer surface of the grinding body 1 is a closed regular dodecahedron composed of 12 regular pentagons 2, and the edge of each regular pentagon 2 Coinciding with the edges of five regular pentagons 2 adjacent to the regular pentagon 2, the edge length of the regular pentagon 2 is 10mm, and the area of ​​each regular pentagon 2 is 172mm 2 , the surface area of ​​the grinding body 1 is 2064mm 2 , volume is 7663mm 3 .

[0016] Preferably, the grinding body 1 is a solid grinding body. The solid grinding body has a large mass and has a large impact value when falling, which is helpful for grinding and can maintain a long-term grinding ability.

[0017] Preferably, the grinding body 1 is a hollow grinding body, making the hollow grinding body can not onl...

Abstract

The invention discloses a regular dodecahedron-shaped grinding body of a ball grinder. The outer surface of the grinding body is a sealed regular dodecahedron including 12 regular pentagons; and the seamed edges of each regular pentagon are superposed with seamed edges of five regular pentagons adjacent to the regular pentagon, and are 10 mm. The grinding body related to the invention is a regular dodecahedron-shaped spherical grinding body. When two grinding bodies conduct grinding, comprehensive contact friction between points, lines and surfaces can be generated, so as to improve the yield and the grinding fineness of the ball grinder, and further improve the grinding efficiency. Moreover, the area-weight ratio of the grinding body is high, so as to improve economic benefits, and reduce mineral resource consumption.

Description

technical field [0001] The invention relates to a ball mill used in the technical fields of grinding such as mines, cement plants, and thermal power plants, and in particular to a dodecahedron ball mill grinding body. Background technique [0002] At present, the grinding bodies of ball mills are mainly spheres and cylinders, which have the following disadvantages: [0003] 1. There is only point-to-point contact, or very small surface contact, so the grinding efficiency is low; [0004] 2. The ratio of effective grinding area to weight is low; [0005] 3. The economic benefit is low, and the consumption of mineral resources is relatively large. Contents of the invention [0006] The technical problem to be solved by the present invention is to provide a regular dodecahedral ball mill grinding body which can effectively increase the contact area and have comprehensive contact friction of points, lines and surfaces. In order to solve the problems of the technologies desc...
