4.Grinding balls Mechanical Performance*Steel: Low Carbon Steel, High Carbon and manganese Alloy steel, High Manganese Alloy Steel.*Consistent Surface hardness to Core Hardness (58-65HRC) *Grinding balls reach to the high Impact toughness more than 15J /cm2*The lowest broken rate: 125mm Grinding balls have reached to "0" broken rate all less than 0.5% *Improved wearing rates & toughness maximize the grinding efficiency of the mining and save cost 5. Packing SystemBags: Ball mill balls could be packed in woven bags, 1000kgs per bag. On the pallets and effort in loading & unloadingSteel Drums: Forged Grinding media balls to be packed in steel drums with openable top (with threads), the steel drums packed on pallets made of heat treated wood or plywood. Two drums on each pallet 6. Quality control System Unique Heating Treatment technique greatly influences Forged grinding media balls quality. Improve the surface and volume hardness. Strict quality control system will be followed by each order during production and after production. Our quality control system will enable nearly 90% grinding balls will be sample inspected before loading on board. Lower the buyer purchasing risk when outsourcing ball mill grinding balls from China Improving surface Hardness , Volume Hardness , Impact toughness of grinding media balls .Wear Resistance and lower the breakage rate will lower your grinding balls consumption cost in mining or other industries, Protect your profits and core values under such tough world economic market environment, which is our mission 7. after sales Service
Each batch grinding balls will be filed in documents according to the correspondent heating number.If there are any qualities problems related with this heating number, such as Ball Cracking or Hardness unqualified or steel Chemical composition inconsistent. This batch grinding balls will be replaced for free at our cost during 30 days after the claim.8. Company & Warehouse Show![Grinding Media Balls Manufacturers]()
