Abstract

The utility model provides a grinding medium which comprises a round table body, wherein, the right end of the round table body is provided with a cone, and the left end is provided with a semi-sphere body. As the above technical proposal is adopted, compared with the prior art, the utility model can complete coarse grinding, medium grinding and fine grinding at the same time, thereby improving operating rate of striping materials and grinding, and reducing consumption of grinding mediator.

Description

A kind of milling medium

Technical field:

The utility model relates to the annex of ball mill in a kind of preparation equipment, the milling medium of ball mill use specifically.

Background technology:

Existing milling medium has following several.

1. abrading-ball.The grinding mode of abrading-ball is that point contacts with point, helps fine grinding.But, often cause excessive pulverizing and cause metal loss the large particle crystal mineral of gravity mill and the ore grinding of coarse grain line.2. frotton.The grinding mode of rod is a line and the contacting of line, and its saving grace is at the grinding efficiency height, and the dielectric dissipation amount is low.But its grinding particle size is thick.3. cylinder, round platform.Round platform, cylinder milling medium possess the advantage of rod milling, are the contact of line face, but because its two ends are all the plane, if as a milling medium, because its edge is very sharp, once heat treatment, the big raising of hardness.Above-mentioned mill is situated between, and can only finish in the carse, medium and small mill, function singleness, and consumption is big, and operating efficiency is low.

Summary of the invention:

The purpose of this utility model just provides a kind of wide accommodation, the milling medium of diverse in function.Can finish in the carse, medium and small mill each.

The utility model purpose can realize by following scheme.

The utility model comprises a Rotary-table, and the right-hand member of Rotary-table is a cone, and left end is the semicircle spheroid.Owing to adopted technique scheme, compared with prior art.The utility model can be finished corase grind, middle mill and fine grinding simultaneously.And then improve mill stripping material and grinding operation rate, reduce the consumption of milling medium.

Description of drawings:

Fig. 1. the utility model structural representation.

The specific embodiment:

Contrast Fig. 1 as can be known, the utility model comprises Rotary-table 1, and the right-hand member of Rotary-table 1 is a cone 2, and left end is a semicircle spheroid 3, the aspect ratio of the height of the height of cone 2 and semicircle spheroid 3 and Rotary-table 1 is 1: 2: 6, and the diameter ratio of Rotary-table left end and right-hand member is 200: 93.

Claims (1)

1. milling medium, it is characterized in that comprising Rotary-table (1), the right-hand member of Rotary-table (1) is cone (2), left end is semicircle spheroid (3), the aspect ratio of the height of the height of cone (2) and semicircle spheroid (3) and Rotary-table (1) is 1: 2: 6, and the diameter ratio of Rotary-table left end and right-hand member is 200: 93.
