Abstract

The utility model discloses a kind of novel ore abrasive body, comprise and grind body (10), it is characterized in that: described grinding body (10) is multi-faceted column, it has at least three sides (1), has arcwall face (2) between adjacent two sides (1).It is simple in structure, and milling area is large, and meanwhile, the arcwall face (2) having can reduce and collides with, and end face (3) has the advantage of spherical grinding body for spherical, and grinding effect is good, is applicable to various grinding requirements.

Description

A kind of novel ore abrasive body

Technical field:

The utility model relates to ball mill equipment technical field, relates in particular a kind of abrasive body for various metallic ores and nonmetallic ore ball mill.

Background technology:

In ore dressing industry, the shape of milling medium, size, material and interpolation quality directly can affect the consumption of grinding efficiency, metal recovery rate and metal material.Therefore be, the research emphasis of this area about the research of the shape of milling medium, size, material always.

The milling medium that uses in current ore mill (or claiming abrasive body) is generally spheroidal, cylindrical, truncated cone-shaped etc., for spheroidal medium, in ore mill, be to put and put the way of contact and grind with ore, be unfavorable for carrying out fine grinding, slightly caused metal loss but often cause, make metal material consumption large, reduce grinding efficiency.For cylindrical and truncated cone-shaped milling medium, although the way of contact that they have comprised point, line, surface, grinding particle size is thick, is suitable for corase grind, middle mill, but is unsuitable for fine grinding.

In order to address the above problem, China Patent No. is that CN202506446U discloses a kind of milling medium, its structure is to be made up of the frustum that is positioned at the prism in stage casing and extend to two ends from the bottom surface of polygonal prism cylinder, therefore, in ore mill grinding process, the way of contact is mainly that face contact contacts with line, and wherein the ratio of face contact is larger, and it is particularly suitable for the how broken method of mill less of current ore dressing industry.Therefore this milling medium can reduce the wearing and tearing of milling medium and lining board of grinder, can improve significantly again grinding efficiency.Although but above-mentioned milling medium has solved spheroidal, the cylindrical and existing problem of truncated cone-shaped milling medium to a certain extent.But its milling medium is owing to being polyhedron, general side more than or equal 5 faces, this causes the abradant surface in grinding process less, its grinding efficiency needs further to be improved.

Utility model content:

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of novel ore abrasive body is provided, and it is simple in structure, milling area is large, and meanwhile, the arcwall face having can reduce and collides with, and end face is the advantage that spherical has spherical grinding body, grinding effect is good, is applicable to various grinding requirements.

The scheme that the utility model solve the technical problem is:

A kind of novel ore abrasive body, comprises grinding body, and described grinding body is multi-faceted column, and it has at least three sides, between adjacent two sides, has arcwall face.

Described grinding body is trigone, and it has three sides.

Described grinding body is equilateral triangle body, and it has three sides, and three side sizes are identical.

Two end faces of described grinding body are spherical surface body.

The section radius of described arcwall face is 1mm to 10mm.

Outstanding effect of the present utility model is:

Compared with prior art, it is simple in structure, and milling area is large, and meanwhile, the arcwall face having can reduce and collides with, and end face is the advantage that spherical has spherical grinding body, and grinding effect is good, is applicable to various grinding requirements.

Detailed description of the invention:

Embodiment, is shown in as shown in Figures 1 to 3, and a kind of novel ore abrasive body comprises and grinds body 10, and described grinding body 10 is multi-faceted column, and it has at least three sides 1, between adjacent two sides 1, has arcwall face 2.

Described grinding body 10 is trigone, and it has three sides 1.

Described grinding body 10 is equilateral triangle body, and it is identical that it has side, 1, three of three side 1 size.

Two end faces 3 of described grinding body 10 are spherical surface body.

The section radius of described arcwall face 2 is 1mm to 10mm.

In use, as shown in Figure 2, when three grinding bodies 10 collide, can grind with side 1 is bonded to each other side 1, and one of basic composition is trapezoidal, or multiple grinding bodies 10 collide as shown in Figure 3, and two end face 3 is spherical surface body, i.e. spherical crown, it has the advantage of ball, be that ball is better than cylindrical or truncated cone-shaped aspect fine grinding, make like this it can carry out various grinding requirements, as corase grind, middle mill and fine grinding.
