grinding media

Jinan Haoyang Casting and Forging has been dedicated to the research and production of wear-resistant steel balls for 20+ years. They are made from high-quality steel through precise forging processes, featuring high hardness and low wear characteristics. They are suitable for heavy-duty grinding scenarios in industries such as mining, cement, and metallurgy. As a high-tech enterprise, the products have passed ISO quality system certification. The specifications range from 20mm to 150mm. Customized material formulas can be provided according to customer requirements, ensuring a 30% increase in grinding efficiency. They have gained the trust of customers both at home and abroad.

High Chrome Grinding Media balls Haoyang Hi Chrome Grinding media balls can provide: Cr 1%-28%, hardness: HRC40-66, 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 chrome 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 .

Dense forging structure without internal porosity. Ultra-low breakage rate ≤0.5%. No broken balls or flat balls during grinding, effectively reducing mill downtime.

Our Forged Grinding Media 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 Forged grinding balls high performance Forged Grinding media balls 'Raw Material Purchase : Strategic partnership with standard steel enterprise and sign the long term agreement (50,000 Tons annually ) Purchase directly from Chinese famous standard steel enterprise, such as laigang Group, HBIS, ANSTEEL, XIWANG Special steel . 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 . ( Forged Grinding balls Surface and core hardness test each day each batch and all will be recorded and filed in documents ) .

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 .
