Abstract
The invention provides a crushing roller. The crushing roller comprise a roller shaft and a crushing ring which is arranged on the roller shaft; the crushing ring comprises crushing teeth and key grooves, wherein the crushing teeth are formed on the outer edge of the body of the crushing rings, and the key grooves are symmetrically formed in the inner edge of the body of the crushing rings; and the centers of the key grooves do not coincide with the centers of the crushing teeth. Because the adjacent crushing teeth on the roller shafts are different in height, the clinker taking and crushing capacity of the crushing roller can be improved, and the production efficiency and the economic benefit can be increased.
Description
Technical field
The present invention relates to field of cement production, especially relate to a kind of breaker roll playing chamotte crushing effect.
Background technology
Cement producing line grate-cooler belongs to Thermal Equipment, and mainly the material from rotary kiln is played with cooling, conveying, heat time
The effect received, crush.Material crushing device is middle kibbler roll, and main broken is passed through breaking ring on roll shaft and mutually extruded.
As shown in figure 3, the breaking ring crushing teeth position marshalling of existing grate-cooler and tooth height is equal, breaking capacity is not
Can meet and require.Simultaneously because the restriction of current material, serious wear in use, short life, need to frequently change breaking ring, significantly
Reduce production efficiency, improve production cost.
Content of the invention
The technical problem to be solved in the present invention is to provide a kind of breaker roll it is therefore an objective to improve chamotte crushing ability.
To achieve these goals, the technical scheme that the present invention takes is:
Described breaker roll, including roll shaft and the breaking ring being arranged on roll shaft, described breaking ring includes being located at ring body outer rim
Crushing teeth and be symmetrically arranged at the keyway of ring body inner edge, each crushing teeth tooth is high different, the center between described keyway not with respectively
Center superposition to crushing teeth.
Mutually stagger in the crushing teeth position of adjacent breaking ring and tooth is high different.
Described breaking ring has two kinds, and a kind of center line of the keyway of breaking ring is overlapped with the center line of at least one crushing teeth, separately
A kind of keyway of breaking ring is not overlapped with the center line of crushing teeth, and the crushing teeth number of two kinds of breaking rings is equal, two kinds of broken interannulars
Every being arranged on described roll shaft.
Described crushing teeth top surface heap is welded with wearing layer.
Each alloying element quality proportioning of described wear-resisting layer material is: c:0.38～0.46%, si:1.2～2.1%, mn:
1.0～1.6%, p :≤0.035%, s :≤0.035%, ni:9～12%, cr:26～28%, mo:0.3～0.5%, n:0.8
～1.2%, re:0.7～1.0%.
Described breaking ring is high-wear-resistancecast cast steel part, and in its material, each alloying element quality proportioning is: c:0.12～0.15%,
Si:0.8～1.1%, mn :≤1%, p :≤0.03%, s :≤0.03%, ni:12～15%, cr:19～22%, mo:0.3～
0.5%, n:0.8～1.2%.
Using technique scheme, the high difference of breaking ring tooth on adjacent roll shaft improves broken the gulping down of grog of breaker roll and pulls
Ability and breaking capacity, improve production efficiency and economic benefit.
Stagger in the crushing teeth position of adjacent breaking ring and the high difference of tooth further increases the breaking capacity of breaker roll.Processing
When only need to change breaking ring keyway position and can be achieved with, processing is simple and convenient
Wearing layer improves the anti-wear performance of breaker roll, extends the service life of breaker roll, improves efficiency, reduces
Cost.
The improvement of wear-resisting layer material and broken ring material be effectively improved breaking ring in working order under anti-wear performance,
Extend the service life of breaker roll further.
Brief description

Fig. 3 is the structural representation of breaker roll in prior art.
Being labeled as of in figure:
1st, crushing teeth；2nd, keyway；3rd, wearing layer.
Specific embodiment
Below against accompanying drawing, by the description to embodiment, the specific embodiment of the present invention is made further details of
Illustrate, to help those skilled in the art to have more complete, accurate and deep reason to the inventive concept of the present invention, technical scheme
Solution.
As shown in Figure 1 and Figure 2, the invention provides a kind of breaker roll, including roll shaft with the breaking ring that is arranged on roll shaft,
Breaking ring includes being located at the crushing teeth 1 of ring body outer rim and the keyway 2 being symmetrically arranged at ring body inner edge, and each crushing teeth 1 tooth is high different,
Center between the keyway 2 not center superposition with each pair of crushing teeth 1.
Breaking ring has two kinds, and a kind of center line of keyway 2 of breaking ring is overlapped with the center line of at least one crushing teeth 1, another
The keyway 2 planting breaking ring is not overlapped with the center line of crushing teeth 1, and crushing teeth 1 number of two kinds of breaking rings is equal, two kinds of broken interannulars
Every being arranged on described roll shaft.As long as two kinds of breaking rings change keyway 2 Working position in processing, new adding need not be set
Work frock changes operation, therefore saves manpower reduces cost.
Breaking ring passes through the positioning key location and installation on roll shaft, mutually staggers and tooth in crushing teeth 1 position of adjacent breaking ring
High different.Breaking ring minimum clearance on adjacent roll shaft is 20mm, and during normal work, tooth top and tooth top misplace.Broken grog
Breaking capacity and gulp down the ability of pulling and all thus improve.
Described breaking ring is high-wear-resistancecast cast steel part, and in its material, each alloying element quality proportioning is: c:0.12～0.15%,
Si:0.8～1.1%, mn :≤1%, p :≤0.03%, s :≤0.03%, ni:12～15%, cr:19～22%, mo:0.3～
0.5%, n:0.8～1.2%.
Crushing teeth 1 top surface heap is welded with wearing layer 3.Each alloying element quality proportioning of wearing layer 3 material is: c:0.38
～0.46%, si:1.2～2.1%, mn:1.0～1.6%, p :≤0.035%, s :≤0.035%, ni:9～12%, cr:26
～28%, mo:0.3～0.5%, n:0.8～1.2%, re:0.7～1.0%.
Add appropriate nickel to improve the intensity of steel in new material, and good plasticity and toughness can be kept, at high temperature
There is antirust and temperature capacity.Intensity, hardness and wearability can be significantly improved using chromium, strengthen non-oxidizability and corrosion-resistant simultaneously
Property.The molybdenum adding can make the crystal grain refinement of steel, improves quenching degree and thermostrength, keep enough intensity in high temperature and resist compacted
Change ability；Nitrogen can improve intensity, low-temperature flexibility and the weldability of steel, increases aging sensitivity.By controlling each alloying element
Compositional range, both ensure that high-wear-resistancecast cast steel part anti-wear performance, had improved its service life, in turn ensure that processing of spray
Performance, prevents its processing cost excessive, is unfavorable for processing.
Wearing layer 3 material then improves the constituent content of si, mn further, strengthens anti-wear performance, more with the addition of appropriate rhenium
Element, can crystal grain thinning, control sulfide formation, effectively improve hardness and the anti-wear performance of wearing layer 3.Thus effectively carrying
The service life of high breaking ring, avoids production cost is greatly improved simultaneously.
First breaking ring blank is cast out using casting technique during manufacture, by crushing teeth on breaking ring 1 periphery circumferentially side
Fall certain thickness to overall processing it is ensured that overlaying surface flat smooth, using special purpose machinery, high-abrasive material is heated fusing, heap is soldered to
Facing surface is finally polished flat by crushing teeth 1 top surface.
Above in conjunction with accompanying drawing, the present invention is exemplarily described it is clear that the present invention implements is not subject to aforesaid way
Restriction, as long as employing the improvement of various unsubstantialities that method of the present invention design and technical scheme are carried out, or without changing
Enter and the design of the present invention and technical scheme are directly applied to other occasions, all within protection scope of the present invention.
