The products are produced through hot-rolling and forging processes to ensure a low breakage rate and are widely used in the mining, cement, and thermal power industries. Certified by ISO9001, the company supports full-size customization ranging from 10 to 160mm and exports to over 30 countries worldwide, with an annual production capacity of over 30,000 tons. Its products have performed exceptionally well in international projects such as the Chilean copper mine, with a single consumption of only 0.8kg per ton of ore in wet grinding conditions and a lifespan twice as long. The company continuously innovates in technology to promote energy-saving upgrades in wear-resistant materials.

The self-developed HT-3 heat treatment process has passed ISO 9001 certification, and the life cycle test has reached the international leading level**.

The New development of Forged Grinding balls Production Technology

Forged steel balls can eliminate the defects such as as-cast looseness generated during the smelting process of the metal by forged, optimize the microstructure and save the complete metal streamline, so the quality of forged steel balls is very important. So how to check the quality of forged steel balls. Now I will introduce the requirements and methods for the quality inspection of forged steel balls. I hope it will be helpful to everyone.
