Abstract
The utility model discloses a roller structure of a high-pressure grinding roller. The roller structure comprises a roller of the grinding roller, wherein a roller sleeve is arranged on the roller surface, a plurality of holes with different sizes are distributed in the surface of the roller sleeve, wear resistant stud nails with different sizes are embedded in the holes and are made from wear-resistant materials, and wear resistant stud nails which are made of different materials and have different sizes are embedded in the same roller sleeve. The wear-resistant stud nails which are made of different materials and have different sizes are arranged on the roller sleeve according to the non-uniformity wear of the roller surface of the high-pressure grinding roller on the basis of not changing the integral structure of the original high-pressure grinding roller, the roller structure is simple to implement, and the problems of whole stripping, difficult material liner formation, nonuniform wear and the like of the high-pressure grinding roller during application are effectively improved.
Description
Technical field
The utility model relates to mining high-voltage roller mill technical field, relates in particular to a kind of roll structure of high-pressure roller mill.
Background technology
High-pressure roller mill application abroad starts from the eighties in last century, and is very fast in the cement industry popularization, but promotes comparatively slow on the whole at the mineral manufacture field.In recent years, along with the roll surface wearing problem is overcome gradually and solves, constantly enlarging at the mineral manufacture field and to use.From 20th century the mid-80 to phase early 1990s, external high-pressure roller mill is mainly used in cement industry and diamond mining industry, and obtains using comparatively widely, becomes the main configuration device in the standard technology flow process gradually.From end of the century the mid-90 to 20 20th century, high-pressure roller mill begins to use at the manufacture field of iron gold mine and iron ore gradually, and along with improving gradually of post nail wear-proof technique, the producer of use is more and more.Simultaneously, also carry out industry and pilot-plant test at copper mine and gold ore deposit gradually.From the early 21st century, beginning obtains fairly large application at coloured and the hard ore noble metal mine.
Because what high-pressure roller mill adopted is bed of material disintegrating process, the efficient height of pulverizing generally can reach more than 2 times of ball mill.Increase high-pressure roller mill in the ball mill front, the function of instead of ball mill significantly reduces the specification of ball mill, cuts down the consumption of energy more than 30%.And the ore degree of dissociation of handling through high-pressure roller mill is good, is very suitable for follow-up ore-dressing practice.So high-pressure roller mill still is boundless in the application prospect of mine industry.Particularly in iron ore enterprise, because the grade of the iron ore of China is all very low, the ore amount of producing the required crushing and grinding of the smart powder of iron per ton is big, and what have reaches 15 ~ 20 tons of ores and could produce one ton of iron essence powder, and the discharge capacity of mine tailing is very big.And the ratio of reduction of high-pressure roller mill is big, the fine size of crushed product, can before entering ball mill, ore carry out a large amount of throwing tails, increase substantially the taste into ore grinding stone, reduce the ore amount of ball mill grinding, the energy consumption of saving is very large, and this is the reason of the immature equipment of some bargh's risk use just.Therefore, in high pressure roller mill machine equipment and the technology of very an urgent demand mature and reliable of mine industry.
But there is following problem in the wear-resisting post nail roll surface of high-pressure roller mill in use: 1, wear-resisting post nail takes place easily peel off together with the mother metal monoblock; 2, roll surface can not effectively form the material lining and protect the roller mother metal, causes the mother metal serious wear; 3, the inhomogeneities of post nail wearing and tearing on wide along roller especially arrive use later stage whole roller journey pommel horse shape, causes the squeezing effect variation.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, provides a kind of and has improved the monoblock that high-pressure roller mill in use occurs and peel off, be difficult to form the material lining and the roll structure of the high-pressure roller mill of the problem such as inhomogeneous of wearing and tearing.
The utility model is achieved through the following technical solutions:
A kind of roll structure of high-pressure roller mill, include the roller of roller mill, roll surface is provided with roller shell, be uniformly distributed with the hole that a plurality of sizes do not wait on the surface of described roller shell, be inlaid with the wear-resisting post nail that size does not wait in the hole, described wear-resisting post nail is formed by the high-abrasive material processing and fabricating, inlays the wear-resisting post nail of multiple unlike material and size on the same roller shell.
Described wear-resisting post nail is all different with size along material on the axis direction of roller shell, and wear-resisting post is followed closely along size difference on the circumferencial direction of roller shell.
The utility model has the advantages that: the utility model is according to the inhomogeneities of high-pressure roller mill roll surface wearing, do not changing on the integrally-built basis of original high-pressure roller mill, choose the wear-resisting post nail of unlike material and size at roller shell, realize simply, and improved the problems such as inhomogeneities that material lining and wearing and tearing were peeled off, were difficult to form to monoblock that high-pressure roller mill in use occurs effectively.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of roll structure of high-pressure roller mill, include the roller of roller mill, roll surface is provided with roller shell 1, be uniformly distributed with the hole 2 that a plurality of sizes do not wait on the surface of described roller shell 1, be inlaid with the wear-resisting post nail 3 that size do not wait in the hole 2, described wear-resisting post nail 3 is formed by the high-abrasive material processing and fabricating, inlays the wear-resisting post nail 3 of multiple unlike material and size on the same roller shell 1.
Described wear-resisting post nail 3 is all different with size along material on the axis direction of roller shell 1, and wear-resisting post follows closely 3 along size difference on the circumferencial direction of roller shell 1.
Claims (2)
1. the roll structure of a high-pressure roller mill, it is characterized in that: the roller that includes roller mill, roll surface is provided with roller shell, be uniformly distributed with the hole that a plurality of sizes do not wait on the surface of described roller shell, be inlaid with the wear-resisting post nail that size does not wait in the hole, described wear-resisting post nail is formed by the high-abrasive material processing and fabricating, inlays the wear-resisting post nail of multiple unlike material and size on the same roller shell.
2. the roll structure of high-pressure roller mill according to claim 1 is characterized in that: described wear-resisting post nail is all different with size along material on the axis direction of roller shell, and wear-resisting post is followed closely along size difference on the circumferencial direction of roller shell.
