Abstract
The utility model relates to a grinding device, in particular to a grinding device with a grinding roller and a grinding ring. The grinding device comprises the grinding roller and the grinding ring and is characterized in that wear-resistant boride material layers, which correspond to each other in position, are arranged on the outer surface of the grinding roller and the inner surface of the grinding ring in a circling manner through build-up welding. The wear-resistant boride material layers on the outer surface of the grinding roller and the inner surface of the grinding ring are matched with each other through waved concave-convex grooves. The grinding device mainly aims to solve the technical problems that the wear-resisting property of the wear-resistant material on the grinding roller and the grinding ring is not improved obviously and the service life of a product is not long; and furthermore, the surface area of the contact working surface of the grinding roller and the grinding ring is increased, which is helpful to improve the quantity of production.
Description
Technical field
The utility model relates to lapping device, particularly a kind of lapping device with grinding roller and bull ring.
Background technology
High-pressure roller mill is a kind of high efficiency powder ore equipment that can be significantly energy-conservation, and lapping device is high-pressure roller mill " heart ", and the working life of its lapping device is directly connected to the service life and the production cost of high-pressure roller mill; Therefore, the shock resistance of its lapping device and antiwear property are vital problems.Under the general work situation, the high-abrasive material that high pressure grinding roll adopted obtains shock resistance preferably and wear resistance based on potassium steel or rich chromium cast iron with the content that improves chromium, manganese and carbon.But this high-abrasive material anti-wear performance still improves not quite, and the service life of product is not long, causes use cost higher.
In addition, existing lapping device mainly adopts following structure.
As Fig. 1, grinding roller and bull ring adopt the structure of facing cooperation directly; As Fig. 2, grinding roller and bull ring adopt the tire-like fit structure; As Fig. 3, grinding roller and bull ring adopt the trapezoidal faces fit structure.The design of above-mentioned employing tire-like fit structure and trapezoidal faces fit structure, its main purpose be bonded area, the raising output in order to increase grinding roller and bull ring still.But, grinding roller contacts damage with the collision between the bull ring situation really in use takes place inevitably as the preferable trapezoidal faces fit structure of effect, influenced the service life of product like this.
The utility model content
The purpose of this utility model is to provide a kind of lapping device, grinding roller and the high-abrasive material anti-wear performance on the bull ring that it mainly solves existing lapping device improve little, the technical problem that the service life of product is not long, but also increased the surface area that contacts working face of grinding roller and bull ring, help to improve output.
The utility model solves the problems of the technologies described above the technical scheme that is adopted.
A kind of lapping device, it comprises grinding roller and bull ring; It is characterized in that: described grinding roller outer surface and the equal built-up welding of bull ring inner surface are equipped with the corresponding boride wear-resistant material layer in position.
Described lapping device is characterized in that: the boride wear-resistant material layer of described grinding roller outer surface and bull ring inner surface is the wavy tongue and groove of S and cooperates.
Described lapping device is characterized in that: the highest point height of the S type monomer of described wear-resistant material layer is 35mm, and its width is 26mm.
The beneficial effects of the utility model are.
1, the utility model the utility model lapping device adopted the higher boride of grinding roller outer surface and bull ring inner surface built-up welding hardness replace the carbide of chromium be hard mutually, simultaneously by institutional framework that changes matrix and shock resistance, the wear resistance that form improves resurfacing welding material.Case hardness reaches as high as more than the HRC62, and its special Welder's artistic skill improves more than 2 times the more former life-span of the product serviceability after the welding, improves the anti-wear performance of parts greatly.
2, the boride wear-resistant material layer of grinding roller outer surface of the present utility model and bull ring inner surface is the wavy tongue and groove cooperation of S, has increased the surface area of grinding roller and bull ring, can significantly improve product quality and output.
3, the boride wear-resistant material layer of grinding roller outer surface of the present utility model and bull ring inner surface is the wavy tongue and groove cooperation of S, the working face of tongue and groove is in shattering process, because the camber line of concave surface and convex surface is inconsistent, can form the material liner at bottom portion of groove, reducing grinding roller contacts with collision between the bull ring, effectively eliminate vibration, prolonged the life-span that equipment uses simultaneously.
4, the utility model is particularly suitable for grinding Mohs' hardness 9.3 and following various brittle materials.

The specific embodiment
See also Fig. 4, it is the structural representation of a kind of lapping device of the utility model.It comprises grinding roller 1 and bull ring 4 as shown in the figure; It is characterized in that: described grinding roller 1 outer surface and the equal built-up welding of bull ring 4 inner surfaces are equipped with the corresponding boride wear- resistant material layer 2,3 in position.
The boride wear- resistant material layer 2,3 of described grinding roller 1 outer surface and bull ring 4 inner surfaces is the wavy tongue and groove of S and cooperates.
As shown in Figure 5, the highest point height of the S type monomer of described wear- resistant material layer 2,3 is 35mm, and its width is 26mm.
In sum, be preferred embodiment of the present utility model only, be not to be used for limiting practical range of the present utility model, promptly all equivalences of doing according to the content of the utility model claim change and modify, and all should be technology category of the present utility model.
