Description
Technical field
The present invention relates to belong to the industry production equipment technical field such as cement, metallurgy, coal, electric power, and in particular to a kind of
The wear-resistant device being applied between vertical mill roll sleeve and lining board for grinding discs.
Background technology
Vertical grinding roll cover and lining board for grinding discs are operationally due to by the effect of high extruding force, and contact surface and by grinding material
Between there is differential sliding, contact surface show as grinding and micro cutting.At present, grinding roller of vertical mill compression system mostly is liquid
Pressure-pneumatic spring system presses, and operating pressure is big in operation, rigorous service condition, and wear extent is big, particularly cement, slag mill
Seem especially prominent, and this two kinds of material requirement specific surface area of finished products are high, therefore mobility is big, mill efficiency will be reduced.Grinding machine
When grinding cement, slag under normal circumstances, after general operation March, can be because of roller set and lining board for grinding discs wearing layer serious wear
Yield is caused to be decreased obviously.At this moment it is accomplished by shutting down and online built-up welding is re-started to roller set and lining board for grinding discs surface, the time is at least
5 days are needed, the large-sized grinder time is longer.Repeated overlaying weldability not only needs fee of material, the labour cost of costliness, can also have a strong impact on operating
Rate.For problem above, in the world several big famous Vertical Mill companies make an effort first on material, how to go to select performance more excellent
Abrasive body material more, but study through for many years, different materials finalize the design almost, with most extensive in cement, slag vertical-mill
Effect it is reasonable be exactly cast steel+hardfacing.Thus, it is necessary to design a kind of new scheme to solve, improve existing skill
Defect in art.
The content of the invention
Goal of the invention：It is an object of the invention to solve the deficiencies in the prior art, there is provided a kind of grinding roller of vertical mill roller
Wear-resistant device between set and lining board for grinding discs.
Technical scheme：A kind of wear-resistant device between vertical mill roll sleeve and lining board for grinding discs of the present invention, including grinding roller roller
Set and the lining board for grinding discs being arranged at below mill roll sleeve, the surface of the mill roll sleeve is provided with roller sleeve abrasion resistant layer, lining board for grinding discs
Upper face is provided with the liner plate wearing layer being adapted with roller sleeve abrasion resistant layer；The liner plate wearing layer is equal with the surface of roller sleeve abrasion resistant layer
Grid grinding layer is provided with, the grid grinding layer includes some subelements, and each subelement integrally assumes diamond in shape, the centre of subelement
Position is equipped with wear-resistant medium.
Wherein, subelement is designed using network pattern structure, can strengthen the friction between work area and material
Power, so as to slow down the mobility of grinding material, plays a part of to reduce grinding machine vibration raising mill efficiency.
Further, the inside of the subelement is hollow setting, and the wear-resistant medium is arranged at the centre bit of subelement
Put.
Further, the wear-resistant medium is circular wear-resisting Jie of a diameter of 10～15mm (such as diameter can be 12mm)
Matter, the abrasive media replaces existing wear-resisting layer plane, can reduce between liner plate wearing layer and roller sleeve abrasion resistant layer and and thing
Contact area between material, increases operating pressure, so as to improve material grinding efficiency.
Further, the grid grinding layer is loaded between liner plate wearing layer and roller sleeve abrasion resistant layer by the way of built-up welding.
In order to the hardness and toughness of grid grinding layer can either be improved, the wearability of grid grinding layer, net are ensure that again
Lattice grinding layer is the grid grinding layer by made by hard, wear-resistant alloy, and the grid grinding layer using this material will not be because of
Much higher hard it is excessively crisp and from peeling off between liner plate wearing layer and roller sleeve abrasion resistant layer, and quality is obtained under conditions of condition of equivalent thickness
Mitigate.
Further, the thickness of the subelement be 2～4mm (for example can be 3mm), the outer side edges a length of 45 of subelement
～50mm (for example can be 48mm), a length of 35～40mm of inner side edge (for example can be 36mm) of subelement；And the rhombus
The angle on the adjacent both sides of subelement is 60 ° or 120 °.
Beneficial effect：The present invention with the addition of grid grinding layer on the surface of existing wearable overlay, the grid grinding layer
It is made up of some subelements, each subelement is that the center of hollow setting and subelement is provided with wear-resistant medium, is replaced existing
Wear-resisting layer surface in technology, had both reduced contact area (increasing real work pressure), improved material grinding efficiency, and energy
Enough saving high-abrasive material reduces manufacture and production cost.
Prove through test of many times, compared with prior art, the built-up welding time interval of the present invention can extend 25～30%,
Vertical Mill output increased 5%-10%, Vertical Mill vibration can reduce 30% and metal wear reduces by 25%.
In sum, the present invention breaks through the restriction of conventional art, and clever structure is cost-effective, improves grinding efficiency, has
Wide market prospects.
Description of the drawings
Fig. 1 is the overall structure diagram of the present invention；
Fig. 2 is the structural representation of grid grinding layer in embodiment.
Specific embodiment
Technical solution of the present invention is described in detail below, but protection scope of the present invention is not limited to the enforcement
Example.
As depicted in figs. 1 and 2, the wear-resistant device between a kind of vertical mill roll sleeve of the invention and lining board for grinding discs, including
