Product DescriptionProduct Description40 50 60 70 80 90mm High Impact forged steel balls for millThe raw material is typically high-quality round steel or alloy steel. The specific chemical composition is crucial for determining the final properties of the ball, such as hardness, toughness, and wear resistance. Key alloying elements and their typical ranges include: Carbon (C): 0.40-1.05%Manganese (Mn): 0.50-1.20%Silicon (Si): 0.15-2.00%Chromium (Cr): 0.05-1.70%Phosphorus (P) and Sulfur (S): These are typically kept to a very low maximum, e.g., ≤ 0.05% to prevent brittleness.Surface Hardness: This is the hardness of the ball's outer layer, which directly impacts wear resistance. Typical ranges are 55-65 HRC (Rockwell Hardness). For smaller diameter balls, the hardness can be even higher.Production ProcessManufacturing ProcessingThe manufacturing of cast grinding balls involves several steps to ensure their quality and performance. These steps include:Material Selection: The first step is selecting the appropriate material based on the intended application. Factors such as hardness, wear resistance, and impact strength are considered.Melting and Casting: For cast iron and some steel grinding balls, the selected material is melted in a furnace and poured into molds to form spherical shapes. The casting process allows for the production of balls with consistent dimensions and properties.Forging: Forged steel grinding balls are produced by heating billets of steel and shaping them into spheres using mechanical forging presses. This process enhances the toughness and impact resistance of the balls.Heat Treatment: After casting or forging, grinding balls undergo heat treatment processes such as oil quenching and tempering. This step improves their hardness and wear resistance, ensuring they can withstand the rigors of grinding operations.Quality Control: Throughout the manufacturing process, stringent quality control measures are implemented to ensure the grinding balls meet industry standards. This includes testing for hardness, impact resistance, and dimensional accuracy.High Hardness High Chrome steel Balls Application & FeatureMain application of Grinding Balls For MiningGrinding Balls featuresMining and Mineral Processing: In the mining industry, grinding balls are used in ball mills to grind ores into fine powders, facilitating the extraction of valuable minerals.
