High Chrome Cast Grinidng steel balls Haoyang Chrome casting Ball can provide: Cr 10%-28%, hardness: HRC58-65, Dia.10mm-150mm alloy cast steel balls. The balls have a lot of excellent properties, such as higher hardness, good abrasive resistance, together with a good surface finish and small dimensional allowance after scientific heating treatment, as one type of grinding media, it can be widely used in ball mill grinding systems of mines, cement, building materials and chemical industries,etc. High Chrome Casting grinding balls , chrome concentration is 》10%-14%， Hardness 》HRC 58, High Chrome casting grinding balls is one of the wearable steel balls with better performance -price-ratio, and its extensive usage has won itself a high share in the market .

Raw material Quality Control : The forged grinding balls ' steel rods are purchased from the famous steel company in China ( 50,000 Tons annually ). It will be strictly inspected before into the warehouse. Production Line : Forged grinding balls mainly use Automatic rolling machine for 20mm to 70mm balls . Above 70mm to 150 mm , we will use the labor forging hammer , which will increase the grinding balls intensity and tougness . We have special department of QC teamwork .The QC department director have 10 years experience in this industry . The team is responsible for inspection during production , inspection before delivery. ( Grinding balls Surface and core hardness test each day each batch and all will be recorded and filed in documents ).

Our Forged Grinding balls produced by advanced automatic rolling machine ( Balls from 20mm-70mm) + Labor Air Hammer ( 80mm-150mm) with special Heating treatment and strict quality control systerm , which make our grinding balls high performance Grinding balls 'Raw Material Purchase : Strategic partnership with standard steel enterprise and sign the long term agreement. Purchase directly from Chinese famous standard steel enterprise , such as laigang Group, HBIS, ANSTEEL, XIWANG Special steel .
