Abstract
The invention relates to a cone crusher crushing wall being smaller than 2000 mm in diameter and a manufacturing method, and aims to meet not only the abrasion-resistant requirement of large stone crushing for a rolling mortar wall but also the abrasion-resistant requirement of small stone crushing for the rolling mortar wall during a stone crushing process. The upper part and the lower part of the cone crusher crushing wall are made of Mn13 and high-chromium iron respectively. The cone crusher crushing wall has the following advantages: (1) the fatal defect that stones cannot be crushed during the stone crushing process because a single material (either manganese steel or high-chromium iron) crushing wall suffers different abrasion losses from different sized stones, the upper part of the single material crushing wall is slightly abraded while the lower part thereof is seriously abraded, and a groove is formed in a stone crushing cavity can be fundamentally overcome; (2) the abrasion loss caused by Mn13 at the upper part of the cone crusher crushing wall during the stone crushing process is relatively consistent with that of a crushed stone rolling cavity in the high-chromium iron lower part of the cone crusher crushing wall.
