Abstract
The utility model relates to an ore grinding medium of a ball grinding mill. A plurality of prisms or prism frustums with the same structure are used as the ore grinding medium. The sections of the prism frustums or prisms are hexagonal. The ore grinding medium has the following advantages that all peripheral surfaces of a grinding stage are plane, the probability of surface contact is improved, the material impacting surface of the grinding medium is enlarged, the impacting force is balanced, the proportion of excessively-ground ore grains is lowered, the ore grinding fineness is stabilized and the product quality is improved.
Description
Technical field
The utility model relates to a kind of lapping device, relates in particular to a kind of ball mill ore grinding medium.
Background technology
At present, in the ore grinding process, the employed mill section polycylinder of ball mill ore grinding or Rotary-table, main lapping mode are that point, line contact are ground.This lapping mode has had significant progress than the lapping mode of the point of abrading-ball contact, has improved grinding efficiency, is preventing having obvious advantage aspect overground.But the side of this mill section is circular-arc surface, when grinding intersegmental contacts side surfaces, can only be a contact or line contact, and the face contact of mill section can only be the both ends of the surface contact of mill section, and the probability of this contact is lower.The lapping mode of this point, line contact makes the excessively pulverizing ore particle ratio that exists in the material higher, causes the ball mill energy dissipation, causes follow-up magnetic separator sorting result variation, affects product quality.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model provides a kind of ball mill ore grinding medium, makes mill section surrounded surface be the plane, has increased the probability of face contact, prevents overground.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of ball mill ore grinding medium, described milling medium are the identical prism of several structures or prismoid; Described prismoid or prism cross section are hexagon.
Compared with prior art, the beneficial effects of the utility model are:
Make mill section surrounded surface be the plane, increased the probability of face contact, abrasive media is balanced to the increase of strike area, the hitting dynamics of material, reduces the ratio of pulverizing ore particle, stablizes mog, improves the quality of products.
Description of drawings
Fig. 1 is the prismatic stereogram of the utility model ball mill ore grinding medium.
Fig. 2 is the stereogram of the utility model ball mill ore grinding medium terrace with edge shape.
The specific embodiment
Below in conjunction with Figure of description the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1 and Fig. 2, a kind of ball mill ore grinding medium, described milling medium are the identical prism of several structures or prismoid; Described prismoid or prism cross section are hexagon.
Adopt husky mould, the real shape foundry engieering of die cast or evaporative pattern vacuum is produced terrace with edge or prism mill section.Adopt the mode of machine cuts that the six-edged steel bar is cut into prism mill section.
The utility model makes mill section surrounded surface be the plane, has increased the probability of face contact, and abrasive media is balanced to the increase of strike area, the hitting dynamics of material, reduces the ratio of pulverizing ore particle, stablizes mog, improves the quality of products.
Claims (2)
1. a ball mill ore grinding medium is characterized in that, described milling medium is the identical prism of several structures or prismoid.
2. a kind of ball mill ore grinding medium according to claim 1 is characterized in that described prismoid or prism cross section are hexagon.
