And in the situation with a plurality of star-wheel teeth 47, star-wheel tooth 47 is preferably arranged in a circumferential direction equably.In order to improve working (machining) efficiency, the star-wheel tooth 47 of adjacent star-wheel 41 angle that staggers is arranged.More preferably, from an end of main shaft 46, the star-wheel tooth 47 that is in the star-wheel 41 of odd positions along main shaft is in alignment with each other, and the star-wheel tooth 47 that is in the star-wheel 41 of even number position is in alignment with each other, and the angle that staggers in a circumferential direction between the star-wheel tooth 47 of these two groups of star-wheels 41, shown in Fig. 2 and 3.For a person skilled in the art, as required, star-wheel also can adopt other any suitable arrangements in principle certainly.
The grid section chassis 5 of single roll crusher 1 is arranged on the below of the main shaft 46 of roll shaft star-wheel load module 4.Shown in Fig. 2 and 3, grid section chassis 5 is provided with into a plurality of grid sections 51 of grid-like layout, has gap 52 between the grid section 51.The star-wheel tooth 47 of each star-wheel 41 align with corresponding gap 52 and size on suitable, and enter successively gap 52 neutralization at the rotation process culminant star gear teeth 47 and 52 leave from the gap, namely star-wheel tooth 47 has at least a period of time to be snapped in the gap 52 in rotation process.When star-wheel tooth 47 is snapped in the gap 52, can produce corresponding fragmentation to the sintering feed that is placed on the grid section.
When work, grid section chassis 5 is by means of only illustrating with arrow among the draw-gear 6(figure) draw mobile in the horizontal direction, thereby roll shaft star-wheel load module 4 is moved with respect to grid section chassis 5, and then can make the sintering feed on the whole roughly orthogonal grid section car 5 of 41 pairs of the star-wheels of roll shaft star-wheel load module 4 produce successively fragmentation.
As mentioned above, the operating temperature of star-wheel 41 is about 800 ℃, and this is because the sintering feed on the grid section 51 of grid section chassis 5 is under the higher temperature.For the operating temperature that makes main shaft 46 is unlikely to Tai Gao and damages main shaft 46, need also that in some cases corresponding cooling system is set main shaft 46 is cooled off.
According to an exemplary embodiment, in main shaft 46, be provided with the through hole that connects vertically, cooling water flows into from an end 71 of through hole, from the other end 72 outflows of through hole, as shown in Figure 2.Thereby, the operating temperature that the cooling effect by cooling water can reduce main shaft 46 and be installed in the star-wheel 41 on the main shaft 46, the working life that prolongs main shaft and star-wheel.
Because grid section 51 is directly to contact and bear the vitals of weight with sintering feed on the grid section chassis 5 of single roll crusher 1, therefore, also needs wear-resisting, high temperature resistant and have enough large intensity.Usually be provided with protective cap 53 wear-resisting, high temperature resistant and that have enough large intensity at the top of grid section 51, such as Fig. 3 and shown in Figure 5 for this reason.Similar with star-wheel 41, by only have the protective cap 53 of superperformance in the working position setting, can save material cost, and only need when needed to change protective cap 53 and get final product, grid section 51 does not need to change.
As processing raw material for single roll crusher 1 provides, being the sintering machine (not shown) of sintering feed, it is positioned at the upstream of single roll crusher 1.The protective cap 53 of crown 43, the particularly grid section 51 of the star-wheel 41 on the bogie grates of sintering machine, breast board, heat insulating mattress etc. and the single roll crusher 1 has roughly the same condition of work.Therefore, also need wear-resisting, high temperature resistant and have enough large intensity.

It is pointed out that Sialon plays a part adhesive at this, in some cases, even can not comprise this Sialon material.And corundum (Al
2O
3) and the concrete content (percentage by weight) of carborundum (SiC) also can be determined on a case-by-case basis.And according to another preferred embodiment, the star-wheel crown also can only comprise corundum (Al
2O
3) and carborundum (SiC) in a kind of getting final product.
In addition, it will be obvious to those skilled in the art that the water content 10% of the mud that the above provides also only is exemplary, the material that in fact only needs a person with the qualifications of a general is made and is convenient to moulding by casting and gets final product, even can not adopt water as the sliming material.
And 1450 ℃ of firing temperatures that the above provides also only are exemplary.For a person skilled in the art, the material that component is different may have different sintering temperatures.In fact, if can with this material suitably sintering form, and firing temperature can be decided on concrete performance requirement, material behavior for a person skilled in the art fully.
For the protective cap of grid section, as mentioned above, protective cap is substantially the same with the working environment of star-wheel crown, and both are used, and reach the purpose of broken sintering feed.The technical recipe of protective cap and preparation method and crown adopt essentially identical mode.But for a person skilled in the art, in practice, the varying in size of kibbler roll, its size is different, and the difference of sintering feed is considered strength problem, and the proportioning of raw material also may be slightly different.
With respect to the star-wheel crown, protective cap is relatively simple for structure, also can adopt another kind of prescription, namely with Al
2O
3Be main component, Al
2O
3Content You Xuan＞=45%.Also can only adopt Al
2O
3As raw materials for sintering.According to a kind of preferred embodiment, can Al
2O
3And SiO
2Be main component, wherein, Al
2O
3Content be preferably 45%-99%, Al
2O
3Content higher, wearability is better, but because Al
2O
3The market price comparatively expensive, therefore, cost is just higher.Comprise Al with employing
2O
3Compare with the prescription of SiC, the intensity of this prescription, thermal conductivity and wearability are all much better, but the shrinkage ratio of firing is larger.According to a preferred embodiment, forming method adopts injection forming.Mud moisture content is preferably about 30%.Mould preferably adopts plaster mold.
For example, by containing 95% Al
2O
3Prescription fire the material property that forms and be:
Density=3.7Kg/dm
3
Anti-Compressive Strength＞=150MPa
Kang folding Qiang Du＞=280MPa
Mohs' hardness: 9
Impact flexibility: 3.78KJ/m
2
The above has been described in detail as an example of star-wheel crown and grate bar protection cap example.In fact, for star-wheel crown and protective cap, also can only adopt Al
2O
3Or SiC fires as base stock and forms, and this is because Al
2O
3, SiC itself just has the characteristics of high rigidity, high-wearing feature.
Except the shape difference, its condition of work and grate bar protection cap are basic identical, therefore, also can adopt above-mentioned material to fire and form as the bogie grates of the sintering machine of the upstream equipment of kibbler roll, breast board, heat insulating mattress.
For a person skilled in the art, the basic structure of the bogie grates in the sintering machine, breast board, heat insulating mattress and installation site are known, do not repeat them here.
The functional parts such as the bogie grates of the star-wheel crown of single roll crusher, grate bar protection cap and sintering machine, breast board, heat insulating mattress, condition of work is roughly the same, and the material of selecting at present is metal cast steel, and at high temperature the life-span is subject to larger impact.The utility model adopts and fires crown parts and the protective cap that forms, and they have the characteristics of high rigidity, high-wearing feature, and the life-span can be improved several times, and cost has reduced on the contrary.And corresponding kibbler roll also has corresponding advantage.
