Abstract
The utility model discloses a dry ball mill, belonging to the technical field of chemical test auxiliary equipment. The utility model provides a dry ball mill which can remarkably reduce the labor intensity of operators and improves the production efficiency in the preparation process of fine pulverized coal. The dry ball mill comprises a dry ball mill body provided with a milling cavity; a milling steel ball is also arranged in the milling cavity; and the milling steel ball comprises a big steel ball and a small steel ball which have the different diameters and have the weight ratio of 5: 2.
Description
Technical field
The utility model relates to a kind of dry method ball mill, belongs to chemical industry test support equipment technical field.
Background technology
When studying the evaluation test of water-coal-slurry slurry performance in the laboratory, need the very little fine breeze of preparation particle diameter.Usually adopt lump coal through the jaw crushing crusher machine in the prior art, artificial screening, obtain the coal dust of 0～40 order, two kinds of grades of 40～100 orders, obtain 100～200 order coal dusts with the mortar underhand polish again, obtain 200～400 purpose coal dusts but can't further grind, and to obtain the fine breeze of described order number, must adopt special equipment or means.It is big so not only to have increased labor intensity of operating personnel, and it is low to have reduced production efficiency, and manufacturing cost obviously raises.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of in the preparation process of fine breeze, can significantly reduce labor intensity of operating personnel, the dry method ball seat machine of enhancing productivity.
For solving the problems of the technologies described above the technical scheme that adopts be: a kind of dry method ball mill, comprise the dry method ball mill body that contains the chamber of milling, also be furnished with the steel ball of milling in the described chamber of milling, the described steel ball of milling is made of by the weight ratio that is not more than 5:2 the big small ball of two kinds of different-diameters.
Further be that the diameter of described big small ball is respectively Φ 6mm and Φ 1mm.
Further be that the weight ratio of described two kinds of steel balls is big steel ball: small ball=5:1～5:1.5.
The beneficial effects of the utility model are: by put into two kinds of different sizes of diameter steel ball of milling by weight in the chamber of milling of existing dry method ball mill body.Like this, when the fine breeze that the preparation test needs, quantity according to the coal dust of each test needs, with lump coal through the jaw crushing crusher machine, 0～40 order that artificial screening back obtains and the coal dust of two kinds of grades of 40～100 purposes, add respectively in the chamber of milling of above-mentioned dry method ball mill body and mill, just can obtain to test 200～400 purpose coal dusts that need.Because in the preparation process of 200～400 purpose fine breezes that test needs, underhand polish originally changes into by the dry method ball mill ball milling, and only the screening process behind lump coal breaking just by manually carrying out, thereby reduced labor intensity of operating personnel greatly, improved production efficiency, can also significantly reduce production costs simultaneously.
Description of drawings
Fig. 1 is the front view of a kind of dry method ball mill of the utility model;
Fig. 2 is the right side view of this Fig. 1.
Be labeled as among the figure: the chamber 1 of milling, dry method ball mill body 2, the steel ball 3 of milling.
The specific embodiment
Be as shown in Figure 1 and Figure 2 the utility model provide a kind of in the preparation process of fine breeze, can significantly reduce labor intensity of operating personnel, the dry method ball seat machine of enhancing productivity.Described dry method ball seat machine comprises the dry method ball mill body 2 that contains the chamber 1 of milling, and also is furnished with the steel ball 3 of milling in the described chamber 1 of milling, and the described steel ball 3 of milling is made of by the weight ratio that is not more than 5:2 the big small ball of two kinds of different-diameters.Above-mentioned by in the chamber 1 of milling of existing dry method ball mill body 2, putting into two kinds of different sizes of diameter steel ball 3 of milling by weight.Like this, when the fine breeze that the preparation test needs, quantity according to the coal dust of each test needs, with lump coal through the jaw crushing crusher machine, 0～40 order that artificial screening back obtains and the coal dust of two kinds of grades of 40～100 purposes, add respectively in the chamber 1 of milling of above-mentioned dry method ball mill body 2 and mill, just can obtain to test 200～400 purpose coal dusts that need.Because in the preparation process of 200～400 purpose fine breezes that test needs, underhand polish originally changes into by the dry method ball mill ball milling, and only the screening process behind lump coal breaking just by manually carrying out, thereby reduced labor intensity of operating personnel greatly, improved production efficiency, can also significantly reduce production costs simultaneously.
In the above-mentioned embodiment, in order to improve the coal dust quantity of 200～400 order grades that obtain in each fine breeze preparation process, the diameter of described big small ball adopts Φ 6mm and Φ 1mm respectively; And the weight ratio of described two kinds of steel balls is in big steel ball: the ratio of small ball is the proportional arrangement of 5:1～5:1.5.So just, obtain the quantity of 200～400 order grade fine breezes that single test needs in can the preparation process of a fine breeze.
Claims (3)
