Grinding Balls
GRI’s mining ball business began in 2015, using the most advanced heat treatment technologies, gaining significant experience and market recognition, and supplying steel balls to the world’s leading mining companies, delivering over 120,000 tons per year.
Features
The products are more wear-resistant, more efficient, and more environmentally friendly, and include many types, such as steel balls, steel segments, and grinding rods.
We have participated in drafting and formulating six standards, such as forged (rolled) steel balls, and have obtained more than 20 patents.
This not only demonstrates our leading position in the wear-resistant materials industry, but also provides a solid guarantee for the company’s sustainable development and technological innovation.
Our product portfolio includes an extensive range of materials for mineral extrusion, with sizes from 20 mm to 160 mm.

Heat Treatment
We have integrated advanced Spanish heat treatment technology and collaborated with research institutions to develop our own composite heat treatment process.
This process includes multiple quenching stages, precise control of quenching liquid temperatures, and continuous tempering.
These techniques significantly improve the hardness uniformity across all our steel balls and increase their overall wear resistance.
