Product Description
Manufacturer & Supplier of Grinding Balls & Grinding Media Balls High Chrome
Chrome Alloyed Grinding Balls-Dia20mm-150mm (High Cr/Medium Cr/Low Cr)
Products Description
Grinding ball is widely used in cement, metal mining, power plant and chemical industry etc. The hardness reaches up to 64HRC(the surface and inner hardness tolerance with in 3HRC unit), which makes the wear-resisting property much better than forged ball. The property- low wear rate, good toughness and less breakage, prolongs its life, improves the productivity of the ball mill, and lowers user's cost.
Processing Technique
Intermediate frequency furnace smelting and mix chromium based on requirement.
Constant temperature casting process ensuring the quality, no solid nonmetallic impurity, no pore, no mal-roundness etc...
Oil-immersed quench harden treatment enhance the hardness, annealing process changing the internal organizational structure, lowering the breakage, and improving the performance.
Products inspection was done by advanced spectrometer and durometer imported from Germany.
