Abstract
The utility model relates to the sand mill for the preparation of polishing material, comprises grinding chamber housing and grinding chamber; The top of described grinding chamber first end is communicated with feed path, and described feed path is provided with material bin; The top of the other end of described grinding chamber is connected with the circulation canal being back to material bin; Be provided with the rotor cylinder of drive shaft in grinding chamber, in rotor cylinder, be provided with the stator of the material outlet passage extended to outside described grinding chamber; The space that rotor cylinder is relative with grinding chamber forms grinding passage, and is provided with ultrasonic vibrator on the inwall grinding the relative grinding housing of passage; And feed separation passage rotor cylinder is provided with from grinding channel connection to material outlet passage.Sand mill of the present utility model, the collision effect that ultrasonic vibrator produces can be rotated with rotor high-speed the shearing force produced to superpose, significantly improve grinding efficiency, the particle of cohesion can be pulverized and be dispersed to the degree of primary particle, and domain size distribution is narrower.
Description
Technical field
The utility model relates to technical field prepared by polishing material, and more particularly, the utility model relates to a kind of sand mill for the preparation of polishing material.
Background technology
In the prior art, the powder stock of polishing, such as silica or rare-earth oxidation raw material, normally use airflow milling that powder stock (particle is at 12-100 μm) is pulverized, grain graininess scope 0.2-50 μm after pulverizing, because the domain size distribution of powder is wider, be difficult to as high-quality polishing raw material.In prior art, sand mill grinds comminuting matter by the crushing medium in sand cylinder or abrasive disk, the abrasive disk in rotating shaft is driven to rotate by transmission device, or the stirring rod that drive rotating shaft is provided with stirs the abrasive media in grinding cylinder, the abrasive media of slip polished dish or the motion in grinding cylinder ground is needed to grind.In order to reach required granularity and decentralization, slip needs to grind for a long time in sand cylinder, this lapping mode not only needs to grind for a long time, solia particle size distribution after grinding in slip is uneven, and therefore existing sand mill is often difficult to the requirement reaching polishing powder powder stock.
Utility model content
In order to solve above-mentioned technical problem of the prior art, the purpose of this utility model is to provide a kind of sand mill for the preparation of polishing material.
To achieve these goals, the utility model have employed following technical scheme:
For the preparation of a sand mill for polishing material, comprise grinding chamber housing, and by the grinding chamber of described grinding chamber housing; It is characterized in that: the top of described grinding chamber first end is communicated with feed path, and described feed path is provided with material bin; The top of the other end of described grinding chamber is connected with the circulation canal being back to described material bin; Be provided with the rotor cylinder of drive shaft in described grinding chamber, in described rotor cylinder, be provided with the stator of the material outlet passage extended to outside described grinding chamber; And described rotor cylinder is provided with the concaveconvex structure of annular; The space that described rotor cylinder is relative with grinding chamber forms grinding passage, and is provided with ultrasonic vibrator on the inwall grinding the relative grinding housing of passage; And the feed separation passage described rotor cylinder is provided with from grinding channel connection to described material outlet passage.
Wherein, in described material bin, there is mechanical vibrator, and be provided with material inlet and exhaust outlet on the outer wall of material bin.
Compared with prior art, sand mill described in the utility model has following beneficial effect:
sand mill of the present utility model, the collision effect that ultrasonic vibrator produces can be rotated with rotor high-speed the shearing force produced to superpose, significantly improve grinding efficiency, and the particle of cohesion can be pulverized and be dispersed to the degree of primary particle, and domain size distribution is narrower.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram in sand mill described in embodiment 1.
Detailed description of the invention
Be further elaborated sand mill described in the utility model below with reference to specific embodiment, to help, those skilled in the art conceives utility model of the present utility model, technical scheme has more complete, accurate and deep understanding.
embodiment 1
Fig. 1 shows a kind of sand mill for the preparation of polishing material of sand mill described in the present embodiment, comprises grinding chamber housing 10, and by the grinding chamber 18 of described grinding chamber housing; The top of described grinding chamber 18 first end is communicated with feed path 25, and described feed path 25 is provided with material bin 20, has mechanical vibrator 23, and on the outer wall of material bin 20, be provided with material inlet 21 and exhaust outlet 22 in described material bin 20; The top of the other end of described grinding chamber 18 is connected with the circulation canal 19 being back to described material bin; Be provided with the rotor cylinder 11 of drive shaft in described grinding chamber, in described rotor cylinder 11, be provided with the stator 13 of the material outlet passage 16 extended to outside described grinding chamber; And described rotor cylinder 11 is provided with the concaveconvex structure 12 of annular; The space that described rotor cylinder 11 is relative with grinding chamber forms grinding passage 15, and is provided with ultrasonic vibrator 17 on the inwall grinding the relative grinding housing 10 of passage 15; And the feed separation passage 14 described rotor cylinder 11 is provided with from grinding channel connection to described material outlet passage; The collision effect that ultrasonic vibrator produces can be rotated with rotor high-speed the shearing force produced and superpose by the sand mill described in the present embodiment, significantly improve grinding efficiency, and the particle of cohesion can be pulverized and be dispersed to the degree of primary particle, and domain size distribution is narrower.
For the ordinary skill in the art; specific embodiment is just exemplarily described the utility model; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
