Grinding Ball

Leading the Industry in Wear-Resistant Cast Ball Production

Since November 1997, our company has been engaged in large-scale production of wear-resistant cast balls for ball mills. We currently have four 2-ton medium-frequency induction melting furnaces, two ten-thousand-ton iron mold coated sand production lines, with a daily production capacity of over 90 tons of cast balls. We also have two sets of grinding ball separation and sorting equipment, three high-chromium ball heat treatment lines, with a total production capacity of 30,000 tons. By the end of 2022, our company has produced over 600,000 tons of wear-resistant cast balls for ball mills, with cumulative sales revenue exceeding 3 billion RMB, making it our core product.

Optimizing Heat Treatment Processes

For high-chromium balls with chromium content greater than 10%, they need to be quenched and tempered. For low-chromium large balls with chromium content less than 10%, they need to undergo tempering treatment. The specific process depends on the customer's heat treatment process. In addition, there are three quenching methods: water quenching, oil quenching, and air quenching. The latter two methods are preferable for grinding balls. Furthermore, for ultra-high-chromium balls, air quenching is more suitable than oil quenching.

Both our cast steel balls and steel forgings are produced on fully automated production lines, and the tempering process is completed by fully automated quenching and tempering integrated production lines. The characteristics of our products include high hardness, low wear rate, smooth appearance, and no porosity.
