Description
Technical field
The present invention relates to a kind of zirconium silicate working method and device, particularly the Ginding process of zirconium silicate and superhard material and device.
Background technology
The method of scale operation zirconium silicate is to adopt ball mill to reach many hours grinding of 20-50 at present; The zirconium silicate meso-position radius granularity that produces is about 1.5 μ m; After facts have proved that the zirconium silicate granularity is less than 1.5 μ m; The mill efficiency of the words ball mill that continuation is ground is very low, a lot of producers increase milling time blindly, thus make the ore grinding cost very high; Also have producer directly with the product about 1.5 μ m as final finished, but the zirconium silicate result of use of this kind particle diameter is not good enough, lacking of market competition ability.
Summary of the invention
The object of the invention is exactly the method and the device of a kind of grinding zirconium silicate by stages of proposing in order to solve the inefficient defective of the Zirconium silicate grinding that exists in the prior art.
The technical scheme that the present invention adopts is following:
A kind of method of grinding zirconium silicate by stages is characterized in that having adopted following steps: a, the zirconium silicate raw material is added water, makes zirconium silicate concentration reach 60%-70%, and it was added ball mill grinding 12-15 hour; B, the material in the ball mill emitted add water and stir homogenizing, make zirconium silicate concentration reach 60%-70%; C, the zirconium silicate material after the homogenizing inject is stirred mill carry out fine grinding, milling time 1-5 hour.The optimum revolution scope that stirs mill remains on 150-180rad/min.
The present invention also provides a kind of device of grinding zirconium silicate by stages; It is made up of ball mill, balancing reservoir and stirring mill; The ball mill discharge port arrives the balancing reservoir opening for feed through pipe connection; Be provided with whisking appliance in the balancing reservoir, the balancing reservoir discharge port is connected to through pipeline and mashing pump and stirs the mill opening for feed.
The present invention adopts the segmentation lapping mode, and it is different to make full use of the best comminution ratio of distinct device, farthest reduces abrasion.The present invention is at corase grind stage (D
50>=2.0 μ m) adopt ball mill, can produce in enormous quantities, after corase grind finishes material emitted and carry out fine grinding.Fine grinding stage (D
50≤2.0 μ m) adopt the high-speed stirring mill, can reduce the granularity of product fast, reduce energy consumption.D
50Be meant that the granular mass less than this diameter accounts for granular mass sum 50%.
The invention has the beneficial effects as follows that produce zirconium silicate with this method and can make full use of grinding plant efficient, the granularity with zirconium silicate in 15 hours is worked into minimum 0.6-0.7 μ m, makes that tooling cost significantly reduces, efficient significantly improves.
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Description of drawings:
Fig. 1 is the device and the schema thereof of grinding zirconium silicate by stages provided by the invention.
Embodiment:
One, the device of grinding zirconium silicate by stages provided by the invention
As shown in Figure 1; It is made up of ball mill 1, balancing reservoir 4 and stirring mill 10; Ball milling body 2 is housed in the ball mill 1; The ball mill discharge port is connected to the opening for feed of balancing reservoir 4 through pipeline 3, is provided with whisking appliance 5 in the balancing reservoir 4, and balancing reservoir 4 discharge ports are connected to the opening for feed that stirs mill 10 through pipeline 7, pneumatic diaphragm pump 8 and valve 9.Above ball mill 1, be provided with opening for feed 12, zirconium silicate material 11 adds in the ball mill 1 from opening for feed 12.Be provided with whisking appliance 5 in the balancing reservoir, balancing reservoir 4 upper ends also are provided with filler 6.Described ball mill 1, to stir pneumatic diaphragm pump 8 and the valve 9 that mill 10, mashing pump adopt all are known products, described balancing reservoir, and it mainly acts on is to store material, adds water and stirs, balancing reservoir can be processed voluntarily.
Two, the method for grinding zirconium silicate by stages provided by the invention
1, adopts 5 tons of ball mills, mill tube rotating speed 18-25r/min; The corase grind technological process: 5 tons of zircon sands, 3 tons of water, to grind 12-15 hour, granularity is about 1.8 μ m.
Raw material, water are pressed optimum proportion (material concentration 60%-70%) add ball mill, start ball mill and grind.But when being ground to certain fineness, the grinding effect of ball mill just obviously descends, thereby should not continue to grind.Raw meal particle size is ground to 1.4-1.7 μ m continued and uses ball milling, whenever adds mill 2 hours, and raw meal particle size reduces about 0.05 μ m; Continue to grind and to have only the waste power consumption, increase cost, when particle size reduction during to 1.2 μ m; Continue to grind, granularity remains unchanged basically.Therefore, when raw meal particle size is ground to the 1.8 μ m left and right sides, it is emitted, it is very reasonable and necessary changing next procedure over to.
2, the material in the ball mill is put into balancing reservoir, balancing reservoir volume 10m
3, balancing reservoir stirrer rotating speed 30rad/min opens the balancing reservoir stirrer, homogenizing 5min.Ball mill is in operation process, and some a small amount of material keeps static relatively, be difficult to grind, so granularity is thicker, and raw meal particle size skewness in the whole ball mill.Homogenizing is put into balancing reservoir with the material that ball mill grinding finishes exactly, mixes stirring.Balancing reservoir by the pond at the bottom of, pool wall, stirrer are formed, no particular requirement.Because the process of lapping heating, moisture evaporation in case of necessity to the balancing reservoir moisturizing, keeps material concentration at 60%-70%.
3, the material that with pneumatic diaphragm pump homogenizing is finished injects to stir to grind and carries out fine grinding, reinforced 500kg (about solid content 65%), and rotating speed 150-180d/min, grinding and promptly getting granularity about 1-5h is the product about 1.0 μ m.
Material gets into mill chamber from stirring mill one end, receives the grinding that mill is situated between then in each cross section of mill chamber and shears operation and pulverized.Material does not stop cyclic motion in grinding vessel and cycart; The whisking appliance that the difference of stirring mill and ball mill is to stir in the mill passes to mill Jie with the form of rotating with kinetic energy; Obtain input ability fully between Jie so that grind, thereby make grinding material more be prone to reach desirable smashing fineness.
4, contrast experiment
17 hours data of test 1 usefulness ball mill continuously grinding.
Test 2 usefulness ball mill grindings were used instead and were stirred the barreling mill 1-5 hour after 12 hours.
Visible by table, use the ball mill continuously grinding, granularity descends slowly after 12 hours, and grinding effect is not obvious; Use stirring barreling mill after 12 hours instead at ball mill grinding, raw meal particle size descends significantly, tangible sudden change is arranged, and final size can reach below the 0.9 μ m.
