In the present embodiment, the agitator 3 is solid steel shaft, and 9 and second ribbon 10 of the first ribbon is manganese steel spiral shell
Band, manganese steel ribbon can ensure the rigidity and wearability of stirring ball-milling mechanism, it is not necessary to agitating device is carried out at abrasion resistant coating again
Reason.
Use the process that Wet-dry agitating ball mill of the present invention crushes dry material for：Close slurry and flow into pipe 5 and slurry
Stream outlet pipe 6, opens bin gate 13.Dry material is put into discharge bin 2, medium ball is put into agitator 3, dry material passes through spiral shell
Revolve batcher 1 to be sent into agitator 3, under the stirring action of stirring ball-milling mechanism, material particles and medium ball are in vertical direction
On do shuttling movement.I.e. the medium ball of outer layer and material particles move upwards under the castering action of the second ribbon 10, and internal layer
Medium ball and material particles push away under the first ribbon 9 and moved downward under effect, the anisotropy of movement causes what is moved up and down
Strong stripping mill effect and shear action occur for medium ball and material particles, so as to cause material particles are internal in the process should
Power, which is concentrated, to be occurred to crush.Material scraping plate 12 enhances the microcirculation of internal stereo circulating, under the lateral shear effect of material scraping plate 12
This microcirculation is converted into the shearing release effect between medium ball and material.At the same time, the second ribbon 10 and stirring are connected
The pitman 11 of axis 8, only the second ribbon 10 does not provide power and support, and the transverse direction for enhancing internal stereo circulating is micro- follows
Ring, under the lateral shear movement effect of pitman 11, medium ball and material particles can carry out level side near pitman 11
To tumbling motion, pitman 11 lateral shear effect under this microcirculation be converted between medium ball and material particles
Shear release effect so that material particles granularity in crushing process reduces more rapid, and the material after crushing is in material scraping plate
Discharged under 12 gyroscopic action by siccative discharge port 4.
Use the process that Wet-dry agitating ball mill of the present invention crushes ore pulp for：Bin gate 13 is closed, opens stream of slurry
Enter pipe 5 and slurry effuser 6.Ore pulp flows into pipe 5 by slurry and enters in agitator 3, in the stirring action of stirring ball-milling mechanism
Under, ore pulp and medium ball do shuttling movement in vertical direction.That is the lifting of the medium ball of outer layer and ore pulp in the second ribbon 10
The lower movement upwards of effect, and the medium ball of internal layer and ore pulp are pushed away under the first ribbon 9 and moved downward under effect, movement it is incorgruous
Property cause the medium ball that moves up and down and ore pulp that strong stripping mill effect and shear action occurs, so as to cause ore pulp in this process
Middle internal stress, which is concentrated, to be occurred to crush.The pitman 11 for connecting the second ribbon 10 and agitating shaft 8 enhances internal stereo circulating
Horizontal microcirculation, under the lateral shear movement effect of pitman 11, medium ball and ore pulp can carry out water near pitman 11
Square to tumbling motion, pitman 11 lateral shear effect under this microcirculation be converted between medium ball and ore pulp
Shear release effect so that ore pulp granularity in crushing process reduces more rapid, and the ore pulp after crushing is flowed out by slurry
Pipe 6 is discharged.
It is the application example that mineral aggregate is crushed using Wet-dry agitating ball mill of the present invention below：
Case study on implementation 1
Choose northern Shensi Zhang Jiamao collieries cleaned coal and carry out ore grinding experiment for research object, it is as shown in the table, equally giving sample amount
Under conditions of (2kg) and same feeding granularity (- 0.5mm), had using Wet-dry agitating ball mill of the present invention in material size
On the premise of effect is reduced to -37 μm, the present invention reduces 24% relative to the ore grinding time of common grinding attachment.
Table 1 is common grinding attachment cleaned coal ore grinding index corresponding with Wet-dry agitating ball mill of the present invention
Note：Above test data is the average value of five experiments
Case study on implementation 2
Choose Xiqu Coal Washery in coal for research object carry out ore grinding experiment, equally to sample amount (1kg), be equally fed grain
Spend (- 0.5mm) and under conditions of the same ore grinding time (10min), ore milling product is subjected to laser particle size analysis respectively, draws grain
Spend scatter chart (as shown in Figure 4 and Figure 5).
Wet-dry agitating ball mill of the present invention is in ore grinding time shorter situation it can be seen from Fig. 4 and Fig. 5 contrasts
Under, the yield of -74 μm of grades is larger, has reached preferably first levigate effect, can be very short if the present invention maximized
Time in substantial amounts of mineral are crushed to -74 μm, the yield lifting effect of -74 μm of grade materials is particularly evident.
The above, is only presently preferred embodiments of the present invention, not the present invention is imposed any restrictions, it is every according to the present invention
Any simple modification, change and the equivalent structure transformation that technical spirit makees above example, still fall within skill of the present invention
In the protection domain of art scheme.
