Super High Chromium Grinding Balls Factory and Suppliers in China
Our Super High Chromium Grinding Balls are engineered for extreme durability and high-performance milling applications. Utilizing an advanced metallurgical process involving precise chemical composition (C 2.00-2.70%, Cr 18.00-21.00%) and multi-stage metamorphic treatments, these grinding media offer unmatched hardness and wear resistance for the most demanding industrial environments.
Specifically designed for cement plants and mining mills, these ultra-high chromium balls significantly reduce overall wear and consumption compared to standard high chromium media. By integrating rare earth silicon and yttrium treatments followed by professional oil quenching and tempering, we deliver a product that optimizes production quality while minimizing operational downtime.

Frequently Asked Questions
Super high chrome balls have higher chromium content and undergo advanced metamorphic treatments, resulting in lower overall wear and consumption rates, especially in the second warehouse phase.
Typical sizes range from φ25mm to φ50mm, with φ50mm often used in initial warehouses and φ25mm being more critical for super high chrome consumption in later stages.
Our balls are heated to 970-990°C and oil-quenched, then tempered at 420-430°C. This creates a Martensite + Carbide microstructure that achieves a hardness of 58-68 HRC.
Yes, we offer customization for chrome content (e.g., ZQCr26, ZQCr20, ZQCr12) and hardness to match the specific particle size and hardness of your material.
Our super high chromium grinding balls are designed for high impact strength, maintaining a broken rate of less than 0.5%.
They are widely used in Mining Mills, Cement Plants, Chemical Petroleum processing, Refractory materials, and general heavy machinery grinding.
