Abstract
The invention discloses a method for crushing materials through a crushing machine. An inner turntable throws materials at a high speed, and an outer rotary drum rotate reverse at a high speed, so that the materials are subjected to multiple actions such as impact, mutual collision, shearing and back striking; a built-in rotating sieve is used for automatically separating coarse powder from fine powder; the separated fine powder materials are discharged through a discharging opening; coarse particles climb up to the lower part of a lining of an outer barrel body along a slope-shaped sieve surface under the action of centrifugal force and are continuously subjected to material striking action; a striking plate hammer is firmly fixed on the inner turntable through a mechanical clamping structure and is used for crushing the materials in a manner of easily controlling the dynamic balance of a rotor part. According to the method, the materials can be fully crushed; furthermore, the economical and social benefits of enterprises such as building materials, mines and metallurgy are comprehensively improved from the aspects of energy conservation, high efficiency and the like.
Description
Technical field
The present invention relates to field of cracking machine, especially a kind of method of new type crushing machine broken material.
Background technology
In the industries such as building materials, mine, metallurgy, chemical industry, building, the use of all kinds of disintegrating apparatus is very extensive, the performance of these disintegrating apparatus and function, and directly output and capability of energy dissipation and economic benefit and the social benefit of enterprise used in impact.Current domestic many disintegrating apparatus, material granularity after their fragmentations is still larger and inhomogeneous, makes the first paragraph of grinding machine still must take fine crushing as main, not only make the output of grinding machine be difficult to improve, and capacity usage ratio is extremely low.
Summary of the invention
The present invention addresses the above problem adopted scheme: inner rotary table is shed at a high speed material, and the rotation of outer rotaring tube high-speed reverse makes material be subject to impact, the repeatedly effect such as shock, shearing and counterattack mutually; Adopt built-in rotary screen to carry out automatic separation to thick, fine powder, the powder material after separation is discharged by feed opening, and coarse granule rises to outer simplified liner bottom along domatic compass screen surface under centrifugal action, continues to accept material and impacts effect; Hit bar and adopt mechanical grip sound construction on inner rotary table, rotor portion dynamic balance performance is easy to control.
The invention has the beneficial effects as follows: abundant comminuting matter not only, and be conducive to comprehensively improve economic benefit and the social benefit of the enterprises such as building materials, mine, metallurgy from the aspect such as energy-conservation, efficient.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further detailed.
Fig. 1 is crusher structure schematic diagram.
Wherein, 1. motor; 2. the feed arrangement sieving containing charging; 3. blast pipe; 4. containing the inner rotary table that hits bar and double layer material spreading tray; 5. with the outer rotaring tube of built-in sieve; 6. the hopper sieving containing discharging; 7. motor II; 8. body.
The specific embodiment
As shown in Figure 1, top motor (1) directly drives containing the inner rotary table that hits bar and double layer material spreading tray by shaft coupling crusher structure, and bottom motors II (7), by belt pulley, drives the outer rotaring tube (5) with built-in sieve through V belt.
During work, containing hitting the inner rotary table (4) of bar and double layer material spreading tray, with the outer rotaring tube (5) of built-in sieve High Rotation Speed in the opposite direction.Lump material is (as lime stone, grog or other fragility piece material) by the feed arrangement (2) containing charging screening, fall, through charging, sieve in advance, release after fine powder, enter containing inner rotary table (4) region of hitting bar and double layer material spreading tray, in material Ji Gai district, be subject to the impact of shedding and hit bar of spreading disk and obtain being thrown at a high speed the outer rotaring tube district with built-in sieve, because local area consists of parabola counterpunch board, material then be subject at a high speed now, the strong recoil of the outer rotaring tube parabola counterpunch board that direction of rotation is contrary is hit, angle of attack when recoil is hit is 75 ゜ ~ 78 ゜, brittle material is by sharply broken.Simultaneously, containing hit bar and double layer material spreading tray inner rotary table (4), with outer rotaring tube (5) the gap location material of built-in sieve, be sheared or met and high velocity impact fragmentation occurs by bounce-back and follow-up high-speed material, then again to be thrown to containing the inner rotary table (4) that hits bar and double layer material spreading tray from outer rotaring tube counterpunch board at a high speed, again clash into strike bar.Material through the intense impact that is subject in above-mentioned 3 districts, shear and collide with each other etc. effect and be fractured into powder, after going out material screen screening, qualified products draw off by the hopper (6) containing discharging screening on bottom, the material of bulk rises to outer rotaring tube liner bottom under the driving of centrifugal force along compass screen surface slope, again enter that fracture area is packed by beater plate hammering and the material that flies mutually clashes into and is broken.
The rotary kiln grog of take makes a service test as testing material, and discharging particle diameter is as shown in table 1:
| Particle size range/mm | - 5+ 0. 9 | - 0. 074 + 0. 015 | - 0. 015 |
| Occupy ratio/% | ? 46. 71 | 30. 53 | 22. 76 |
Table 1 occupies ratio branch situation for each particle size range with it, the discharging particle diameter 0.074mm of visible disintegrating machine has accounted for below
53.29%, the analog computation of doing according to people such as German R. Asmus, under same material condition, mill feed material grain diameter is less, and mill output is higher, if particle diameter reaches Blain specific surface 150 ~ 200 m<sup TranNum="82">2</sup>/ kg, the output of Ball Mill System can improve 100%, Energy Intensity Reduction 24% ~ 30%, this will contribute to subsequent ball milling machine to bring into play preferably grinding function.Through repeatedly actual condition test, this disintegrating machine is when guaranteeing finished product materials particle diameter 100% < 5 mm, and average current drain is
1.?7?kWh?/?t。And domestic conventional disintegrating machine is when guaranteeing particle diameter 95% < 5 mm of finished product materials at present, average current drain is
2. more than 0 kWh/t, this disintegrating machine has not only obviously promoted crushing effect, and also makes unit power consumption decline more than 10%.
Claims (3)
