Our Steel Ball Skew Rolling Mill is a continuous, integrated system designed for the efficient production of high-performance grinding media. Starting from steel rods, the process encompasses automated feeding, precise induction heating, high-speed skew rolling forming, followed by controlled slow cooling, inline quenching, and tempering. This seamless sequence ensures each ball achieves optimal metallurgical properties for demanding applications in mining and cement industries. The line concludes with automated cooling, weighing, inspection, and packaging, delivering ready-to-use products of consistent quality and durability.
The skew rolling mechanism produces balls with exceptional geometric accuracy and surface quality, foundational for reliable performance.
The integrated quenching and tempering system allows for precise hardness profile control, achieving a core-to-surface hardness difference below 5 HRC.
The process yields a dense, toughened microstructure that directly translates to low breakage rates and extended operational lifespan in mills.
The entire sequence from heating to final inspection is automated, ensuring process stability and reducing variability.
