Frequently Asked Questions
High chrome balls (typically >10% Cr) offer significantly higher hardness and superior corrosion/wear resistance compared to low chrome balls, making them ideal for abrasive materials and corrosive environments.
While used in several sectors, the mineral mining, cement manufacturing, and power industries benefit most due to the need for grinding hard clinker, metal ores, and pulverized coal.
We utilize a specialized oil quenching heat treatment and optimize the chemical composition (C, Si, Mn, Cr) to create a balanced microstructure of Martensite and Carbides, keeping the broken rate below 0.5%.
Yes, Chengda provides tailor-made alloying options. Based on your technical analysis and test work, we can adjust the chrome content anywhere from 0.8% to 28%.
We manufacture a comprehensive range of sizes, typically from 10mm up to 140mm, to accommodate everything from fine grinding to primary crushing mills.
Due to their high density and maintained roundness, high chrome balls improve grinding efficiency, allowing the mill to reach target fineness faster, thereby reducing total energy consumption per ton.
