1. Ball mill grinding media annual output 200, 000 tons 2. Casting and forging grinding meida balls available size 25-150mm 3. The high-speed production lines are all controlled by computers, which decreases manual intervention and guarantees product quality and stability. 4. From source to finished product, we strive to manufacture high-quality and high performance grinding steel balls. We set up a professional technical team with the cooperation of research institutions, colleges, and universities. For instance, chinese academy of sciences are our direct cooperator, professor mr bern klein university of british columbia, canada is one of our team members. Shandong iraeta has 8 leading grinding ball production lines with annual output of 200, 000 tons. We also provide efficient energy-saving and consumption-reducing solutions for the global mining giants including rio tinto and bhp billiton.

1)hardness Surface hardness of forged ball ranges from hrc55 to hrc67. Core hardness of forged ball ranges from hrc50 to hrc55. Average volume hardness (avh) ranges from hrc55 to hrc63. All requirements about hardness can be customized according to different grinding condition. 2)density Average density is 7.85g/cm3. Consistency is higher than ordinary ones. 3)component analysis Raw material is high carbon alloy steel, and the promotion of alloy elements is under 5%. 4)impact value Impact toughness value is more than 12j/cm2 5)metallographic structure Tempered martensite forms when tempered. The best microstructure is fine needle martensite. 6)breakage rate Actual breakage rate is not greater than 0.5% and close to 0. 7)raw material As we know, the quality of forged grinding piece depends on the material by 80%. Our products use high-quality round steel from national large-scale steel mill to insure the quality of our products.
Steel Shot is used for surface finishing, cleaning, descaling, deburring, casting sand removal, coating removal and surface preparation. Steel Grit is used for industrial foundry, forging plant, heat treatment shop, steel construction plant, container manufacturer, ship builder, auto and locomotive manufacturer
1 ) product feature 1 > high hardness: surface hardness: hrc57-67 hrc, volume hardness hrc56-64. 2 > high impact toughness: the impact toughness of our grinding balls is more than 12 j / cm2. 3 > low broken rate: the actual broken rate is not higher than 1%. 4 > good wear-resistant and lower wear rate.
Grinding steel ball include: forging steel grinding balls: dia 20mm --- dia 150mm; the high, medium and low Chrome alloyed casting iron balls: dia17mm --- dia 100mm. They mostly apply in various mines, cement plants, power stations, chemical industries etc. The specialties: high hardness, no breakage, good wear resistance, even wearing and also it has obtained a high reputation from customers in domestic and foreign market.
