Problems solved by technology

But at present, the roller retainers of these two types of roller surfaces are ordinary steel plates welded with wear-resistant electrodes. Since the wear resistance of such roller retainers is not as good as that of the working surface in the extrusion zone, it is easy to cause the wear of the roller surface. Crescent shape, resulting in uneven particle size of the high-pressure roller mill, reducing the yield of the finished product of the high-pressure roller mill

Embodiment Construction

[0030] The present invention will be further described below in conjunction with accompanying drawing.

[0031] Such as Figure 1-6 , a high-pressure roller mill roller, including a roller 1 with a cemented carbide stud 3 on the roller 1 .

[0032] Carbide roller retainer 2 is also installed on the roller 1, and the carbide roller retainer 2 is composed of the cylindrical part of the carbide roller retainer, the connecting part of the carbide roller retainer and the square body of the carbide roller retainer. One end of the connecting part of the cemented carbide roller retainer is connected with the cylindrical part of the cemented carbide roller retainer, and the other end is connected with the square body of the cemented carbide roller retainer. The cylindrical part of the cemented carbide roller retainer includes hard Alloy roller retainer cylinder arc surface 2a and carbide roller retainer cylinder bottom plane 2b, the cemented carbide roller retainer square body part in...

Abstract

The invention discloses a high-pressure roller mill roller retainer, a roller and an assembly method. The high-pressure roller mill roller retainer is a hard alloy roller retainer. Compared with the prior art, the protected high-pressure roller mill roller retainer is stable in performance and convenient to mount and prevents the roll surface of a high-pressure roller mill from being non-uniformly abraded (to be abraded into a crescent shape).

Description

technical field [0001] The invention relates to the field of mining machinery manufacturing, in particular to the field of high-pressure roller mill manufacturing, and in particular to a high-pressure roller mill roller retainer, a roller and an assembly method. Background technique [0002] High-pressure roller mills are commonly used equipment in the field of stone and mineral processing. At present, there are mainly two types of working surfaces for rollers: alloy steel roll skins inlaid with carbide studs and wear-resistant casting roll skins. Due to the working principle and structural form of the high pressure roller mill, a part of the material will be discharged directly along the edge of the roller surface without being squeezed and crushed before entering the extrusion zone, so it is necessary to install a roller retainer on the edge of the roller of the high pressure roller mill , in order to reduce the probability of the material being discharged directly without...
