High Chrome Cast Iron Grinding Balls from Germany

These are cast iron grinding balls with high chromium content, typically 10-18%, used in ball mills for grinding ores and minerals. They fall under HTS 7325.91.00.00 as cast articles of iron or steel specifically designed as grinding balls for mills. Their hardness and wear resistance make them ideal for mineral processing applications.

Import Tips

Verify chemical composition certificates to confirm cast iron/steel content and avoid misclassification under Chapter 72 unwrought metals

Include mill test reports showing hardness (e.g

HRC 58-65) and size specs to prove grinding ball function during customs review
