Abstract
The utility model relates to a kind of sand mill, and comprise the grinding chamber limited by the internal side wall of sand cylinder and end cap, sand cylinder is horizontally disposed with; Grinding chamber is communicated with feed path near the side of end cap, feed path is provided with material supply warehouse; Grinding chamber is communicated with exit passageway away from the side of end cap; Rotor grinding is provided with between feed path and exit passageway, described rotor grinding is provided with the concaveconvex structure of annular, thus between described rotor grinding sand cylinder internal side wall corresponding thereto, form grinding passage, and be also provided with ultrasonic vibrator in the sand cylinder internal side wall that grinding passage is relative; And the junction of described grinding passage and described exit passageway is provided with Separation.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 prepared for 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.
To achieve these goals, the utility model have employed following technical scheme:
A kind of sand mill, comprise the grinding chamber limited by the internal side wall of sand cylinder and end cap, described sand cylinder is horizontally disposed with; It is characterized in that: described grinding chamber is communicated with feed path near the side of end cap, feed path is provided with material supply warehouse; Described grinding chamber is communicated with exit passageway away from the side of end cap; The rotor grinding of drive shaft is provided with between described feed path and exit passageway, described rotor grinding is provided with the concaveconvex structure of annular, thus between described rotor grinding sand cylinder internal side wall corresponding thereto, form grinding passage, and be also provided with ultrasonic vibrator in the sand cylinder internal side wall that grinding passage is relative; And the junction of described grinding passage and described exit passageway is provided with Separation.
Wherein, described driving shaft is by brushless electrode drive.
Wherein, mechanical vibrator is provided with in described material supply warehouse.
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 of sand mill described in the present embodiment, and it comprises the grinding chamber 20 limited by the internal side wall of sand cylinder 10 and end cap 14, and described sand cylinder 10 is horizontally disposed with; Described grinding chamber 20 is communicated with feed path 16 near the side of end cap 14, feed path 16 is provided with material supply warehouse 18, and in order to prevent material from condensing and blocking feed path, is provided with mechanical vibrator 19 in described material supply warehouse; Described grinding chamber 20 is communicated with exit passageway 17 away from the side of end cap; The rotor grinding 12 that driving shaft 11 drives is provided with between described feed path 16 and exit passageway 17, described rotor grinding 12 is provided with the concaveconvex structure (not shown) of annular, described driving shaft is by brushless electrode drive (not shown), thus between described rotor grinding 12 sand cylinder internal side wall corresponding thereto, form grinding passage 21, and be also provided with ultrasonic vibrator 13 in the sand cylinder internal side wall that grinding passage is relative; And the junction of described grinding passage and described exit passageway is provided with Separation 15(such as only allows the particle being less than 10 μm to pass through).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 particle at the silica of 12-100 μm or Rare earth oxide polishing powder powder stock, can obtain grain size scope after the sand mill process of the present embodiment is 0.2-10 μm.
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.
Claims (3)
