Abstract
The utility model discloses a found grinding roller structure, including the grinding roller body, its characterized in that: a plurality of recess has been seted up at the outer periphery middle part of grinding roller body, the notch of recess is less than the tank bottom, a plurality of wear-resisting groove has been seted up to the outer periphery both sides of grinding roller body, the casting has the cermet body in the wear-resisting inslot, the utility model discloses the advantage compared with prior art lies in: the groove can block part of grinding materials, then the materials in the groove and the materials outside the groove are ground, the grinding efficiency is improved, the contact area between the outer circumferential surface of the grinding roller body and the grinding materials is reduced, the abrasion of the grinding roller body is reduced, the abrasion resistance of the grinding roller body can be greatly improved through the metal ceramic body, the problems of cracks and edge breakage are reduced, and the service life of the grinding roller body is prolonged.
Description
Technical Field
The utility model relates to a found and grind technical field, specifically indicate a found mill grinding roller structure.
Background
The vertical mill is a grinding device integrating fine crushing, drying, grinding, powder selecting and conveying, and is widely used for grinding and superfine grinding of various solid materials in the industries of cement, building materials, electric power, metallurgy, chemical engineering, non-metal ores and the like, the solid materials enter the vertical mill from a feed inlet of the vertical mill and are ground by a grinding roller, a grinding disc and other components, wherein the use of the grinding roller can be influenced by factors such as the grindability of a grinding object, the pressure between the grinding roller and the grinding disc, the balance degree between the grinding roller and the like, the problems of cracks, edge breakage and the like at the outer circumferential surface of the grinding roller are easy to occur, the service life is influenced, and the wear resistance of the grinding roller is still provided with a certain lifting space, so that improvement is necessary.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to overcome above technical defect, provide a stand grinding roller structure that stand wear and tear, long service life.
In order to realize the purpose, the utility model discloses the technical scheme who adopts is: the utility model provides a found grinding roller structure, includes the grinding roller body, a plurality of recess has been seted up at the outer periphery middle part of grinding roller body, the notch of recess is less than the tank bottom, a plurality of wear-resisting groove has been seted up to the outer periphery both sides of grinding roller body, the cermet body has been cast in the wear-resisting inslot.
The grooves and the wear-resistant grooves are arranged at intervals along the circumferential direction of the grinding roller body.
The groove is of a round table structure.
After the structure is adopted, compared with the prior art, the utility model the advantage that has is: the utility model provides a found grinding roller structure of grinding includes grinding roller body, recess, cermet body etc. the recess can block partial grinding material, then the material in the recess is ground with the material outside the recess, has not only improved grinding efficiency, has still reduced the area of contact of the outer periphery of grinding roller body and grinding material, has reduced the wearing and tearing of grinding roller body, through the cermet body, can promote the wearability of grinding roller body greatly, reduce the crackle, the limit problem bursts up, the life of extension grinding roller body.
Drawings
Fig. 1 is the structural schematic diagram of the grinding roller structure of the vertical mill of the present invention.
Fig. 2 is a schematic view of a sectional structure of a groove in a grinding roller structure of the vertical mill of the present invention.
As shown in the figure: 1. grinding roller body, 2, recess, 3, wear-resisting groove, 4, cermet body.
Detailed Description
The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.
Examples, see fig. 1-2:
a vertical grinding roller structure comprises a grinding roller body 1, wherein the cross section of the grinding roller body 1 is circular, a plurality of grooves 2 are formed in the middle of the outer circumferential surface of the grinding roller body 1, notches of the grooves 2 are smaller than the groove bottom, when grinding is carried out, the grooves 2 are smaller than the groove bottom, and partial ground materials can be clamped into the grooves 2, so that the materials in the grooves 2 and the materials outside the grooves 2 are ground mutually, the grinding efficiency is greatly improved, the contact area between the outer circumferential surface of the grinding roller body 1 and the ground materials is reduced, the abrasion of the grinding roller body 1 is reduced, the service life of the grinding roller body 1 is prolonged, the grinding materials are better clamped by the grooves 2, furthermore, the grooves 2 are of a circular truncated cone structure, a plurality of wear-resistant grooves 3 are formed in two sides of the outer circumferential surface of the grinding roller body 1, metal ceramic bodies 4 are cast in the wear-resistant grooves 3, and the metal ceramic bodies, the grinding roller has higher hardness, mechanical property and wear resistance, is high in bonding strength with the grinding roller body 1, is wear-resistant, can effectively improve the wear resistance of two sides of the outer circumferential surface of the grinding roller body 1, reduces the problems of cracks, edge breakage and the like of the two sides of the outer circumferential surface of the grinding roller body 1, and prolongs the service life of the whole grinding roller.
In order to ensure the stability of the grinding roller body 1, the grooves 2 and the wear-resistant grooves 3 are further arranged at intervals along the circumferential direction of the grinding roller body 1.
The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
