The present invention provides a kind of roller, including matrix, matrix is provided with component, component axially consecutive setting in matrix, and the component is staggered by different materials.The present invention protects roller, extends the service life of roller, and height squeezes mill efficiency and guaranteed.And impact load is reduced, keeps equipment operation more steady.
Description
Technical field
The present invention relates to a kind of roller for grinding or crushing, further relate to include this roller rolling device.
Background technique
Roller is usually to be used in rolling device, for grinding or comminuting matter.It is when usual roller crushing material
It is realized using the protrusion that roller matrix surface is arranged in.
Protrusion in existing equipment mainly by being arranged several studs higher than matrix surface in matrix surface, stud and
There is interval between stud, by stud come pressing materials, to achieve the effect that grinding or comminuting matter.But stud roller is squeezing
One-pass finished rate is not high when pressure or comminuting matter, and in addition the service life of stud roller is not grown, and the abrasion loss of roller is big.
CN204194013A discloses a kind of roller, cord is arranged on matrix, the cord is by convex block close-packed arrays
It constitutes, and convex block is axially consecutive in roller.Design in this way effectively improves one-pass finished rate when roller crushing material.But
It is that the service life and service efficiency of roller and rolling equipment need to be further increased.
Summary of the invention
The purpose of the present invention is to provide a kind of rollers and rolling equipment for improving service efficiency and service life.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of roller, including matrix, matrix are provided with component, component axially consecutive setting in matrix, the component by
Different materials are staggered.Different materials of the present invention refer to different component different structure or with component different models etc.
Material can be the identical material difference trade mark, be also possible to the material of unlike material.For example, hard alloy K01 and K20, iron and
The materials such as steel；Arrangement can there are many permutation and combination, such as K01-K20-K01-K20-K01, K20-K01-K01-K20, iron-
Steel-iron-steel-iron or iron-steel-steel-iron etc. etc..The difference between material is taken full advantage of, the wear rib for avoiding roller is squeezing
Phenomena such as causing component to arch upward because of expanded by heating in pressure work, fall off, fracture, protects roller, extends roller
Service life, height squeeze mill efficiency and are guaranteed.And impact load is reduced, keeps equipment operation more steady.
There can be gap between the component of above-mentioned different materials, it can also be with gapless.
Preferably, component is identical in the height of matrix upper process.Gapless between component.Efficiently use the thermal expansion of storeroom
Coefficient difference avoids the generation of roller wear rib premature failure, ensure that the long-time of roller just so that thermal expansion is buffered
Often work.
Preferably, gap is equipped between component or/and in component.The spacing in above-mentioned gap can be < 10mm, 10~<
20mm, 20~50mm.The spacing in gap is controlled, it can be achieved that different demands for granule size.Such as different materials,
The partial size of different spacing grinding products achieved is as follows:
Table 1
| Handle material | Coal mine | Iron ore | Limestone mine |
| Spacing 10mm | ≤8mm | ≤10mm | ≤6mm |
| 10~< of spacing 20mm | ≤16mm | ≤20mm | ≤15mm |
| 20~50mm of spacing | ≤45mm | ≤50mm | ≤40mm |
On roller circumference, above-mentioned gap can be staggered (i.e. same cross section of the gap not on roller circumference),
It can also be in same cross section.It is more efficient, crowded to squeeze comminuting matter not on the same cross section of roller circumference for preferred gap
Press better effect.
In order to further increase roller service life, while component being avoided to split in the generation along the direction of roller matrix surface
Line, above-mentioned matrix setting is fluted, and wear-out part is located in groove.The groove can be a through slot in axial direction, can also be with
It is multiple-grooved obstructed each other.
Preferably, the component is located in groove with embedded mode.The insertion can be interference fit, or
Clearance fit, the clearance fit can be to be adhesively fixed or welding manner is connected and fixed by metal adhesive.Preferably
The clearance fit that metal glue caking agent is adhesively fixed, this cooperation are relatively interference fitted good realization in technique, also avoid groove
The influence expanded with heat and contract with cold to connecting portion.
In order to further increase service life, the bottom width of the component is not less than the width of component and roll surface intersection
Degree.Even if component ruptures on roller diameter direction, the use of roller is nor affected on.
In order to further increase service life, the cross sectional shape of the component can be rectangle, trapezoidal, L shape, T shape, convex
Deng.Preferred cross-sections shape be it is trapezoidal, in handling ease, use even if having abrasion it is not easily to fall off.
In order to further increase the wearability of roller, the height that the component is higher by roll surface accounts for the 5% of component whole height
~50%.Wearability and service life are improved simultaneously.
In order to further increase the service life of roller, the component in same groove is higher by the height one of matrix roll surface
It causes.
Above-mentioned component, which arranges the shape to be formed in matrix surface, can be interruption or continual linear type, zigzag, herringbone
Shape, arc etc..Preferably linear type is conducive to processing groove and component, effectively reduces cost.
In order to further increase one-pass finished rate when roller crushing material, the both ends of the roller are provided with rib,
The rib is between circumferentially-adjacent component.Preferably, the rib is a part of matrix, and rib and cord etc.
Height further increases one-pass finished rate.
Above-mentioned component can be one or more kinds of dimensions, can form any width, reduce purchase cost, reduce
Mold takes, and enhances the versatility and interchangeability of protrusion.
In the present invention, the monoblock type roller that the roller can be integrated for roll shaft and matrix, be also possible to roll shaft and
Matrix is the composite roll of two components.
Beneficial effect
1. it is negative to the impact of roller that the present invention in the case where guaranteeing one-pass finished rate (20%~30%), reduces grinding
Lotus, reduced rate can reach 10-40%, and the even running of equipment and the loss for components such as bearings is effectively guaranteed.
2. the present invention further improves the service life and wearability of roller.Service life can be improved 10% or so, can
To reach 16000~22000 hours, abrasion loss reduces 5-15%, and the use of abrasion loss after 2100 hours is only 2.3mm.
