We produce and sell Grinding Steel Ball for Mining industry since 1995.
Our Grinding Steel Ball 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.
2. Production facility: At present we use advanced automatic production line which makes sure the quality is highly consistent.
3. Quality Control: Our company has an independent laboratory, the advanced and accurate lab equipment, to ensure that each step of the production process is performed in accordance with the quality standards.
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.
