20MM TO 150MM Grinding Media Forged Steel Ball For Ball Mill

Junda forged steel ball, relied on advanced equipment and production technology, our forged steel  ball has the advantages of high hardness, good wear resistance, no fracture, uniform wear and so on. The forged steel ball  Mainly used in various mines, cement plants, power stations, chemical industry and other industries.  In order to ensure the excellent performance of grinding ball, we have established a perfect quality testing system, advanced quality control and testing equipment.  We have also obtained ISO 9001:2008International quality system certification. Hoping for your cooperation.

Junda company produces φ 20 to φ 150 forged steel balls ,we select high quality round steel,low-carbon alloy,high manganese steel,high carbon and high manganese alloy steel  as raw material   produced by air hammer forging process.  We select high-quality round steel as raw materials, and adopt advanced equipment, unique heat treatment process and strict quality control system to make sure the better performance of forged steel balls in the overall hardness. the surface hardness is up to 58-65HRC, volume hardness is up to 56-64HRC.  The hardness distribution is uniform, the impact toughness value is 12J/cm², and the crushing rate is far less than 1%.  Forged steel ball chemical composition: carbon content is 0.4-0.85, manganese content is 0.5-1.2, chromium content is 0.05-1.2, We can produce different size according to customer’s request.  We have also obtained ISO 9001:2008International quality system certification.
