Abstract
The invention discloses a method for producing diamond micro-powder by using a vibration ball mill. According to the invention, the vibration ball mill is used for carrying out crushing and grinding shaping upon diamonds, such that the diamond micro-powder is obtained. The vibration ball mill comprises a frame, a vibration exciter, a grinding cylinder body, an electric control system, a cooling system, and a grinding media. When the diamond micro-powder is produced, the diamonds are placed into the grinding cylinder body of the vibration ball mill; the vibration exciter generates high-frequency circular vibration, such that the grinding media in the grinding cylinder body performs combined rotational vibration impact movements comprising high-speed autorotation, low-speed revolution, and vibration. Therefore, impact effect is performed upon the diamonds, and the diamonds are crushed, such that the diamond micro-powder is obtained. As a result of practices, the vibration ball mill has excellent performances in diamond crushing and grinding shaping. Crushing and shaping speeds are high, production efficiency is higher than that of other methods, and the obtained diamond particles have good roundness and reasonable particle size distribution. Therefore, application requirements by actual production upon diamond micro-powder can be completely satisfied, and a surprising technical effect is obtained.
Description
Technical field
The present invention relates to a kind of method of utilizing vibrator to produce diadust, belong to the diamond abrasive production field.
Background technology
At present, diamond abrasive mainly adopts the production of polishing of emery wheel, emery cloth and sand paper.Wherein, emery wheel is topmost abrasive product, is mixed by a certain percentage by abrasive material and bond, and sintering forms behind die forming, also must carry out shaping, balance and overspeed test at last.Emery cloth and sand paper are the larger abrasive product of another kind of output, are to be cohered on base material (cloth or paper) by abrasive particle, cut into after drying the goods of different size.In addition, also can adopt grinding or finishing method to make diamond abrasive.The diadust diameter that existing these methods make is larger, and production capacity is low, and size distribution is unreasonable.
Summary of the invention
For the weak point that above-mentioned prior art exists, the object of the present invention is to provide a kind of method of utilizing vibrator to produce diadust, utilize existing vibrator that diamond is carried out fragmentation and grinds shaping.
Purpose of the present invention is achieved through the following technical solutions:
A kind of method of utilizing vibrator to produce diadust, utilize vibrator that diamond is carried out fragmentation and grinds shaping, to obtain diadust, wherein vibrator comprises frame, vibrator, grinding jar cylindrical shell, electric-control system, cooling system, abrasive body; When producing diadust, diamond is put into the grinding jar cylindrical shell of vibrator, vibrator produces the high frequency circular vibration, makes the abrasive body in the grinding jar cylindrical shell form percussion to diamond, so that diamond is broken, thereby obtains diadust.
Further, the abrasive body of grinding jar cylindrical shell adopts stainless steel to make, and the grinding jar barrel diameter is 300～600mm, long 300～600mm.Preferably, abrasive body adopts the stainless steel bar form, and diameter is 10～30mm, long 280～580mm, and stainless steel bar and adamantine weight ratio are 1:3～6.
The grinding jar cylindrical shell adopts the cooling system cooling, and is preferred, and cooling system adopts water quench.
On probation through different ball mills, find vibrator in the diamond fragmentation and grind in the shaping to show excellent performance, not only speed broken and shaping is fast, its production efficiency is also high than other method, and the diamond particles roundness that obtains is good, rational size distribution satisfies actual production fully to the instructions for use of diadust, has obtained unexpected technique effect.
Description of drawings
Fig. 1 is the structural representation of the vibrator that adopts of the present invention.
The specific embodiment
Below in conjunction with embodiment the present invention is described in further detail, but embodiments of the present invention are not limited to this.
Utilize vibrator that diamond is carried out fragmentation and grinds shaping, to obtain diadust, wherein vibrator comprises frame 1, vibrator 3, grinding jar cylindrical shell 2, electric-control system, cooling system, abrasive body; When producing diadust, diamond is put into the grinding jar cylindrical shell 2 of vibrator, vibrator 3 produces the high frequency circular vibration, the whirling vibration ballistic motion that makes the abrasive body in the grinding jar cylindrical shell 2 produce high speed rotation, low speed revolution and combination of vibrations, with this diamond is formed percussion, so that diamond is broken, thereby obtain diadust.
The operation principle of vibrator: motor 4 drives axle rotation with the vibrator 3 of eccentric hammer by flexible coupling and Hooks coupling universal coupling, make the grinding jar cylindrical shell produce vibration, thereby so that abrasive body and diamond overturn in the grinding jar cylindrical shell, impact, so that diamond is broken and grind shaping.Cushioning effect is played in the vibration of 5 pairs of vibrators of buffer, with the protection vibrator.
Find in the actual production that abrasive body adopts the stainless steel bar best results, the diameter of stainless steel bar is grown 280～580mm for being 10～30mm, and stainless steel bar and adamantine weight ratio be 1:3～6, and Ball-milling Time can be adjusted selection according to actual needs.
The stainless steel bar length direction is interior axially consistent with the grinding jar cylindrical shell, and is shorter than axial length 20～30mm in the grinding jar cylindrical shell; Between the stainless steel bar, line contacts between stainless steel bar and the grinding jar cylindrical shell, impact and abrasive power even, can effectively control the diamond grit variation; Noncontact space between the stainless steel bar, between stainless steel bar and the grinding jar cylindrical shell is lacked than spherical abrasive body, has increased the collision probability of diamond in cylindrical shell; And the cutting action of stainless steel bar can be so that the needle bar shape diamond particles be fractureed the roundness of diamond particles after improving fragmentation and grinding shaping.
In addition, the weight ratio between stainless steel bar and the diamond is unsuitable excessive, too large, and the diamond particles shape difference after the grinding fragmentation is too little, reduces production efficiency.It is suitable that the time of vibratory milling will be selected, oversize, and particle size distribution can become greatly, and is too short, do not reach broken requirement, and generally speaking, Ball-milling Time is 3～24 hours.
The above has been described in detail the preferred embodiment for the present invention by reference to the accompanying drawings, but the present invention is not limited to above-mentioned embodiment, in the ken that those of ordinary skills possess, can also under the prerequisite that does not break away from aim of the present invention, make various variations.
