Grinding Media steel balls in china
We are well aware of the importance of Forged and Casting Grinding Steel Ball to the crushing industry, and providing customers with more wear-resistant steel balls has been our constant pursuit for 25 years. Years of accumulation of technology and experience have made our product quality control increasingly perfect, and we have been able to see more and more customers adding value due to the use of our products.
Our Forged and casting balll grinding media have following advantages:
1. Material Quality: We buy steel materials directly from Laigang Group, JIYUAN, which are the biggest steel companies in China who specially produce steel for grinding balls
