Rolling mortar wall of cone crusher, composed of two-component material, and manufacturing method

Abstract

The invention relates to a rolling mortar wall of a cone crusher and a manufacturing method, wherein the rolling mortar wall of the cone crusher is composed of a two-component material, not only can meet the wear-resistant requirement of large block crushing to the rolling mortar wall, but also can meet the wear-resistant requirement of small block crushing to the rolling mortar wall during the stone crushing process, the upper part of the rolling mortar wall is made of high manganese steel, the lower part of the rolling mortar wall is made of high-carbon chromium steel, and a ring-shaped groove is formed in the outer wall or the inner wall of the lower part of the rolling mortar wall, and forms concave-convex casting matching with a ring-shaped groove formed in the inner wall or the outer wall of the upper part of the rolling mortar wall. The rolling mortar wall provided by the invention has the advantages as follows: 1, the rolling mortar wall fundamentally overcomes the critical defect of incapability of crushing stones due to groove formation in a stone crushing cavity, caused by small abrasion at the upper part of the rolling mortar wall and large abrasion at the lower part of the rolling mortar wall, since the abrasion losses caused by that stones in different specifications to the rolling mortar wall are different during the stone crushing process by the rolling mortar wall made of the single material; secondly, the abrasion loss, produced in stone crushing, by high manganese steel at the upper part of the rolling mortar wall is relatively in accordance with the abrasion loss caused by that the lower part of the high-carbon chromium steel rolling mortar wall rolls the stone crushing cavity.

Description

technical field [0001] The invention relates to a cone crusher made of a two-component material that can meet the wear-resistant requirements of the wall of the rolling mortar for crushing large stones and the wear-resistant requirements of the wall of the rolling mortar for crushing small stones in the process of crushing stones. The constituted cone crusher rolling mortar wall and its manufacturing method belong to the field of cone crusher component assembly manufacturing. Background technique [0002] CN101954456A, the name "manganese steel crushing wall for casting cone crusher or the manufacturing method of the rolling mortar wall", the manufacturing method includes the following steps: (1) according to the different sizes, specifications and models of the cone crusher crushing wall or the rolling socket wall, Manufacture the real sample mold of the broken wall or the wall of the rolling mortar; (2) design and manufacture the corresponding wall thickness and the overal...

Problems solved by technology

However, because the cone crusher has two different working states from the crushing of large stones to the crushing of small stones in the process of crushing stones, the upper part of the rolling mortar wall is used to crush large stones, and the large stones are crushed against the rolling mortar wall. The upper part forms an impact load, and the stone material forms an indefinite, not all contact impact extrusion fit with the wall of the mortar and the crushing wall, so the wear state of the wall of the mortar and the upper part of the crushing wall is relatively small; The lower part of the mortar wall and the crushing wall is a cavity for crushing of crushed stones, and the crushed small stones form overlapping and fully contacting crushed stones with the rolling mortar wall, and the small crushed stones located between the rolling mortar wall and the crushing wall are in the rolling mortar. Under the strong extrusion of the crushing wall and the crushing wall, the crushed small stones will seriously wear the rolling mortar and the crushing wall.

If a single material is used to make the wall of the rolling mortar and the crushing wall, no matter it is high manganese steel or high chromium cast iron, the amount of wear on the wall of the rolling mortar is different due to the different sizes of stone materials, resulting in small wear and tear on the upper part of the wall of the rolling mortar and the crushing wall. The case where the wear in the middle part is smaller than that in the upper part, and the wear in the lower part forms grooves (see image 3 ), causing the wall of the rolling mortar and the broken wall to be worn and scrapped
