Specific embodiment
The utility model is further described below with attached drawing combined with specific embodiments below.
Embodiment 1
As shown in Figure 1 and Figure 2, a kind of autogenous tumbling mill of the present embodiment, including discoid centrifugation mill 1, rack 2, driving machine
Structure and removal device 6；Wherein, driving mechanism and removal device 6 are mounted in rack 2, and 6 inside of removal device is arranged in centrifugation mill 1
Top simultaneously drives rotation by driving mechanism, and the outside of centrifugation mill 1 is covered with shaft screen 4, cylindrical cap 5 is covered on the outside of shaft screen 4, in circle
Storage is formed between barrel cover 5 and shaft screen 4 across the space of the material of 4 sieve pore of shaft screen；Removal device 6 is equipped with discharging channel, cylindrical cap 5
Space between shaft screen 4 is connected to the discharging channel of removal device 6, and the top of shaft screen 4 is provided with feed hopper 3.
It should be noted that being along the circumferential direction equipped with multiple centrifugal breaking hammers 101 on centrifugation mill 1, centrifugation mill 1 is right
The grinding campaign of material is generated by 101 agitation material of centrifugal breaking hammer.In the present embodiment, centrifugal breaking hammer 101 is strip
Shape is bolted on centrifugation mill 1, replaces after facilitating abrasion, the radial direction of length direction edge centrifugation mill 1,
Here there are 4 equally distributed centrifugal breaking hammers 101.In addition, centrifugation mill 1 upper surface from outer side to centre-height gradually
It reduces, forms inclined-plane, centrifugal breaking hammer 101 is arranged on the inclined-plane, and it is one that material, which throws away rear motion profile from centrifugation mill 1,
A upward parabola, since the speed that different size material flies out is not identical, so that height when contacting with shaft screen 4 is not yet
Together, there is material distribution along the entire short transverse of shaft screen 4, thus impact and relatively small, the shaft screen 4 of abrasion to shaft screen 4
It is not easy to get stuck, screening effect is good.
In use, material to be ground is added into shaft screen 4 by feed hopper 3, centrifugation mill 1 is driven to revolve by driving mechanism
Turn, 101 agitation material of centrifugal breaking hammer, so that material generates autogenous grinding campaign, material particular diameter grinding reaches a certain size can be from cylinder
Sieve 4 is passed into cylindrical cap 5, and the discharging channel through removal device 6 is collected, and can adjust centrifugal force according to material size,
Shaft screen 4 is replaced according to required product granularity.
In the present embodiment, driving mechanism includes motor 7, shaft 8 and bearing block 9；Wherein, bearing block 9 is arranged in removal device 6
Inside, shaft 8 is mounted in bearing block 9 by bearing, and the upper end of shaft 8 connect with centrifugation mill 1, and the lower end of shaft 8 is pacified
Fill big belt wheel 10；Motor 7 is arranged in the rack 2 in 6 outside of removal device, and the output shaft of motor 7 installs small pulley 11, big belt wheel 10
It is sequentially connected with small pulley 11 by belt 12, motor 7 is rotated for drive shaft 8.
Since centrifugal breaking hammer 101 is directly contacted with material in grinding, and stirs material and generate autogenous grinding campaign, so from
Heart quartering hammer 101 is larger by the collision friction of material, is also most easily worn component, i.e. vulnerable part in autogenous tumbling mill, needs
Often it replaces.In order under the premise of reducing cost as far as possible, improve its wearability, the present embodiment is in centrifugal breaking hammer 101
It is inlaid with wear-resisting stud 102.It is specific as shown in Figure 3 and Figure 4, stud hole is opened up on centrifugal breaking hammer 101, wear-resisting stud 102 is embedding
Enter in stud hole, and using interference fit, fixes reliably, under prolonged impact friction operating condition, will not be taken off from stud hole
Fall, and 102 lower end of wear-resisting stud be taper or spherical shape, it is abundant with column Bolt-hole fits, make wear-resisting 102 stress of stud more evenly, no
Frangibility is here taper；Meanwhile the material of wear-resisting stud 102 uses hard alloy, has high rigidity and wearability, certainly,
The higher material of other hardness can also be used.It can be seen that being mentioned by inlaying wear-resisting stud 102 in centrifugal breaking hammer 101
Its high integral hardness, to improve its wearability, reduction abrasion extends the service life, reduces replacement frequency, guarantees that equipment is lasting, high
The operation of effect.
Importantly, being ground according to centrifugal breaking hammer 101 when rotary work with material collision on the basis of above structure
Wear-resisting stud 102 is only embedded in centrifugal breaking and hammers 101 upper surface into shape and along the side in rotary work direction by the position characteristics of material
On face, and the side little wear for carrying direction of rotation does not inlay wear-resisting stud 102, farthest saves making for alloy stud
With quantity, cost is reduced；Meanwhile the upper surface of centrifugal breaking hammer 101 is plane, the one side on operative orientation is inclination
Face, material elder generation and the inclined surface making contact, then rise to its upper surface along inclined surface and be fully ground, and material is not easy card
In centrifugal breaking hammer 101 and corner formed by centrifugation mill 1, make material autogenous grinding sufficiently, uniformly.As shown in figure 5, in order to meet
Meet the convenience of above structure and processing simultaneously, centrifugal breaking hammer 101 is in width direction, and upper part is trapezoidal, i.e. its upper surface
Front and rear sides be all inclined surface.
Embodiment 2
A kind of autogenous tumbling mill of the present embodiment, it is substantially the same manner as Example 1, the difference is that, the present embodiment is to shaft screen 4
Shape is improved, and the end surface shape of shaft screen 4 is polygon, and preferably the end surface shape of shaft screen 4 is regular pentagon, regular hexagon
Or octagon, regular hexagon is selected in the present embodiment.
Sieve is generally cylindrical in existing grinder, directional velocity after such structural materials fly out from centrifugation mill 1
It is contacted with the non-forward direction of sieve, has and centainly cut angle, material size smaller than sieve mesh must could pass through sieve, to lead
It causes obtained product granularity to be less than design granularity, and is easy to get stuck, and this equipment uses the shaft screen 4 of polygon, passes through control
Be centrifuged 1 revolving speed of mill, after may make most of material to fly out with the respective face of shaft screen 4 almost perpendicular contact, to filter out
The slot size of material size and shaft screen 4 is almost the same, i.e., is consistent with design, and products obtained therefrom particle size uniformity is good.
Embodiment 3
A kind of autogenous tumbling mill of the present embodiment, it is substantially the same manner as Example 2, the difference is that: in feed hopper 3 and shaft screen 4
Between be provided with transition bucket 13, to charging protect, prevent material from flying out from feed hopper 3 and cause danger, at the same also avoid because charging
It is damaged caused by the shock of shaft screen 4.
Schematically the utility model and embodiments thereof are described above, description is not limiting, attached drawing
Shown in be also one of the embodiments of the present invention, actual structure is not limited to this.So if this field
Those of ordinary skill enlightened by it, without deviating from the purpose of the present invention, not inventively design
Frame mode similar with the technical solution and embodiment, all should belong to the protection range of the utility model.
