According to the utility model, the roller edge wear resistance is improved through the design structure of roller edge hardening, so that the service life of the high-pressure roller mill is prolonged.
Description
Technical Field
The utility model belongs to the technical field of crushing machinery, and particularly relates to a roller system component of a high-pressure roller mill.
Background
The high-pressure roller mill is widely applied to various industries such as cement, metal mines and the like by depending on the efficient lamination crushing principle, and becomes a preferred device for increasing crushing amount, reducing grinding amount, saving energy and improving yield. The high-pressure roller mill grinds the materials under the action of force between the material layers and by means of the opposite rotation of the fixed roller system and the floating roller system, so that the surfaces of the roller systems are greatly abraded. At present, a roller system of a high-pressure roller mill adopts studs fixed on the surface of a roller sleeve to grind materials, and when the high-pressure roller mill works, the materials are filled between the studs to form a self-generated wear-resistant material pad, so that the roller surface is protected, and the durability of the roller is improved.
When a traditional high-pressure roller mill roller system works, abrasion is uneven, the extrusion stress of the roller edge on materials is reduced, the materials are rough at the roller edge, and meanwhile, the roller edge is extremely worn during material crushing, so that the roller edge needs to be strengthened to reduce the abrasion loss of the roller sleeve edge, and the service life of the high-pressure roller mill is directly influenced by the quality of the hardened roller edge.
Disclosure of Invention
Aiming at the problems, the utility model makes up the defects of the prior art and provides a roller system component of a high-pressure roller mill; according to the utility model, the roller edge wear resistance is improved through the design structure of roller edge hardening, so that the service life of the high-pressure roller mill is prolonged.
In order to achieve the purpose, the utility model adopts the following technical scheme.
The utility model provides a roller system component of a high-pressure roller mill, which comprises a fixed roller system and a floating roller system, wherein the fixed roller system and the floating roller system correspond to each other, and both the fixed roller system and the floating roller system comprise a main shaft and a roller sleeve which are correspondingly installed.
Further, the boss is a regular polyhedron.
Further, the mounting hole is a cylindrical hole.
Further, the upper surface of the roller edge hardening block is a circular arc.
Furthermore, the large studs are arranged in the middle of the surface of the roller sleeve, and the small studs are arranged on two sides of the surface of the roller sleeve.
The utility model has the beneficial effects.
The roller edge hardening structure is realized, the wear resistance of the roller edge is improved, the roller edge hardening blocks are not easy to collapse under the action of extrusion force, and the service life of the high-pressure roller mill is prolonged.

The mark in the figure is: the device comprises a fixed roller system 1, a floating roller system 2, a main shaft 3, a roller sleeve 4, a boss 5, a mounting hole 6, a roller edge hardening block 7, a roller edge pin shaft 8, a large stud 9, a small stud 10 and an end flange baffle 11.
Detailed Description
The embodiment provides a roller system component of a high-pressure roller mill, which is shown in the attached drawings and comprises a fixed roller system 1 and a floating roller system 2, wherein the fixed roller system 1 and the floating roller system 2 correspond to each other, and the fixed roller system 1 and the floating roller system 2 respectively comprise a main shaft 3 and a roller sleeve 4 which are correspondingly installed. The fixed roller system 1 and the floating roller system 2 do circular motion together to extrude and crush the materials.
The surface of the roller sleeve 4 is subjected to complex heat treatment, so that the wear resistance of the roller sleeve is more suitable for extruding and crushing high-strength materials. A plurality of bosses 5 are arranged on the two sides of the roller sleeve 4 along the circumference, and the bosses 5 are regular polyhedrons. Each boss 5 is provided with a mounting hole 6, and the mounting holes 6 are cylindrical holes.
Each boss 5 is provided with a roller edge hardening block 7, the upper surface of each roller edge hardening block 7 is a circular arc, and all the roller edge hardening blocks 7 form a complete ring shape after being folded, and form a roller edge hardening surface along the radial direction. The roll edge hardening blocks 7 are formed by mainly sintering tungsten carbide, the same cylindrical holes corresponding to the mounting holes 6 are formed in the roll edge hardening blocks 7, each roll edge hardening block 7 is connected with each boss 5 through a roll edge pin shaft 8, and the roll edge hardening blocks 7 are mounted on the roll sleeve 4. The arrangement of the roller edge hardening block 7 cancels a linear cutting process, saves cost, is simple to manufacture, and avoids the damage of linear cutting to the material performance.
The surface of roller shell 4 is provided with big stud 9 and little stud 10, and big stud 9 sets up in roller shell 4 surperficial middle part, and little stud 10 sets up in roller shell 4 surperficial both sides. The large stud 9 and the small stud 10 are both higher than the surface of the roller sleeve 4, and the exposed heights of the large stud 9 and the small stud 10 are used for extruding materials and forming a material cushion to protect the shaft sleeve in the process.
Two side surfaces of a roller sleeve 4 of the fixed roller system 1 are both connected with end flange baffles 11 which are used for blocking a grinding part between the fixed roller system 1 and the floating roller system 2 and preventing ground objects from falling out of a grinding area.
It should be understood that the detailed description of the present invention is only for illustrating the present invention and is not limited by the technical solutions described in the embodiments of the present invention, and those skilled in the art should understand that the present invention can be modified or substituted equally to achieve the same technical effects; as long as the use requirements are met, the method is within the protection scope of the utility model.
