Market Demand Change and Product Structure Adjustment of Wear-resistant Parts Industry of Mining Crushing Equipment

The demand of mine enterprises for wear-resistant accessories has changed from simply pursuing low prices to comprehensively considering the balance of "life - cost - efficiency". Through structure optimization, such as changing grate end face into triangle structure, eliminating ventilation dead angle, improving ventilation area by 9.29% and extending service life by 10%, such products with performance improvement and cost optimization are more popular in the market. In the high-temperature wear environment, the chromium series wear-resistant and heat-resistant cast iron products can maintain excellent performance under 700-800 ℃ through the lamination sand shell core casting process and stack casting technology, effectively solving the industry problem of frequent failure of traditional products.

The regional market presents the characteristics of differentiated development. Northwest and other mining concentrated areas have a strong demand for high-performance wear-resistant accessories, and the local market share exceeds 89%, reflecting the concentrated demand of regional mining development for high-end accessories. Meanwhile, with the development of emerging mining markets along the "Belt and Road", the export potential of medium-end wear-resistant accessories with high cost performance gradually emerges.
