Description
Technical field
The present invention relates to a kind of compression roller of high-pressure roller mill, be particularly useful for the Novel squeeze roller type roller surface structure that various brittle material was pulverized/ground to the industrial circles such as building materials, metallurgy, mine, coal, chemical industry.
Background technology
At present, high-pressure roller mill is mainly used in the industrial circles such as building materials, metallurgy, mine, coal, chemical industry, and the compression roller of two opposite direction rotatings of high-pressure roller mill, under hydraulic system effect, produces huge extruding force by crushing material.The roll surface Life Relation of compression roller is to operation rate and maintenance cost.The stud that the stud surface structure of conventional high-tension roller mill adopts is appeared and is exceeded roll surface, under the effect of hydraulic high-pressure power, when containing the special hard materials such as iron block in the material be extruded, the mortal injury that will cause breakage to the stud exposing head or fracture, and be arranged in post holes with interference fit form due to stud, therefore stud is damaged, fractureing is difficult to extract when post holes, be unfavorable for the independent replacing of stud and the sustainable use of roller shell, even have to whole roller shell to be scrapped, add the duration and cost of maintenance of equipment.
High-pressure roller mill most critical equipment life in industry park plan be exactly extruding the roll surface life-span, especially in the operation of the magnetic material such as iron ore, iron ore concentrate, the iron block removed in material is comparatively difficult, particularly be imbedded in the little iron block of material depths, fatal harm will be caused to roll surface after these little iron blocks enter high-pressure roller mill, high-pressure roller mill equipment roll surface in current industry park plan, especially stud formula roll surface, cause the phenomenon of roll surface heavy damage very general because entering iron block, very large impact is created on the life-span of equipment.
Summary of the invention
The object of the invention is the deficiency for solving the problems of the technologies described above, a kind of Novel squeeze roller type roller surface structure is provided, have that impact resistance is strong, hardness is high, hard formation is dark, erosion resistance is strong, etc. feature, maintenance of equipment expense can be reduced, reduce the maintenance of equipment time, greatly improve the service life of operation rate and roll surface.
The present invention is the deficiency solved the problems of the technologies described above, the technical scheme adopted is: a kind of Novel squeeze roller type roller surface structure, comprise roller shell and stud, be interspersed post holes and groove is provided with at the outer surface of roller shell, stud is with matched in clearance form and be arranged in post holes by bonding agent, and the upper surface of stud is concordant or lower than the outer surface of roller shell.
The material of described roller shell is steel alloy.
Described roller shell outer surface is provided with one deck hardened layer.
The thickness of described hardened layer is 30 ㎜-50 ㎜.
The hardness of described hardened layer is HRC55-70.
The hardness of described stud is HRC65-80.
The shape of described groove is spherical or hemispherical.
The invention has the beneficial effects as follows:
1, the present invention is applicable to the industrial circle brittle mineral grinding operations such as metallurgy, mine, coal, chemical industry.Its stud flush type surface structure is made up of roller shell, high-strength wearable alloy stud, and working roll mask of the present invention has the features such as impact resistance is strong, hardness is high, erosion resistance is strong, long service life.
2, stud formula roll surface many employings stud head height in the past goes out roller surface certain size form, because stud hardness ratio is higher, be afraid of that hard object is impacted, when containing the material of the ultrahards such as iron block in the material be extruded, the easier stud to exposing head will cause breakage or the fatefulue injury such as to fracture, this compression roller class surface structure just can avoid this phenomenon, be particluarly suitable for operative employee between the on-stream period of equipment initial stage unskilled and do not understand device structure time, avoid the situation because destroying Roller of High when user's maloperation causes and enters hard object, substantially increase running rate and the roll surface life-span of equipment.
3, this compression roller class surface structure, roller shell Surface Machining has and point to be covered with the staggered spherical hole of roll surface or hemispherical hole structure, one deck spontaneous formula material backing strap can be formed on roller shell surface when machine utilization operates, bear the special hard material such as wearing and tearing and iron block with backing strap to impact, this structure backing strap forms speed, thus has both improve the impact that the wearability of roll surface and life-span turn improve the anti-hard object of roll surface stud.
4, this compression roller class surface structure, adds the frictional force of roll surface and storeroom, and the performance making roll surface be engaged material significantly improves, and improves the mill efficiency of high-pressure roller mill.
5, this compression roller class surface structure, when stud is damaged, when this stud can be heated to more than uniform temperature, bonding agent is made to lose viscosity, what the stud hole due to stud and roll surface adopted is matched in clearance, is easy to be extracted and is replaced with new stud, and roller shell then can continue to use, easy to maintenance due to stud, thus extend the life-span of roll surface.
