Material Assurance 
Analysis certificate
l The steel certificate must be delivered to HY together with the batch steel
l Inspection department must confirm that the steel certificate and the steel bar label are the same
l Heating number from the material certificate is linked to HY documents in file for Customer tracking
Production Management System
Forging Grinding balls by Air hammer Hot rolling grinding balls
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
Grinding balls QC System
QC team-work : QC manager with more than 10 years’ experience in this industry and the team workers will test each batch grinding balls during production and inspection before delivery ( Surface & Core Hardness test , impact value and etc will be recorded in file according to different Steel Heating number , easily for future Tracking )
Packing System
Bags: Grinding balls could be packed in woven bags, 1000kgs per bag. On the pallets and effort in loading & unloading
Steel Drums: Grinding 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
