Ø60 Steel Ball Skew Rolling Mill
Featuring high operational stability, this Ø60 Steel Ball Skew Rolling Mill efficiently produces 60mm grinding balls with consistent batch-to-batch hardness. With a roundness error maintained under 0.6mm, it is ideal for high-demand applications in mining, cement production, and power generation
Product Introduction
Utilizing high-frequency induction heating (1050–1100°C), the Ø60 Skew Rolling Mill forms grinding balls in a single pass via counter-rotating rolls, delivering a defect-free surface and pore-free internal structure. Post-quench performance reaches 60–65 HRC from surface to core with roundness error maintained within 0.6mm. The system maximizes ROI by offering high production stability, minimal scrap rates, and superior roll durability for heavy-duty grinding applications.

Product Advantages
High Dimensional Precision
Diameter tolerance reaches ±0.5mm with a roundness deviation of <1%, ensuring stable movement trajectories within the ball mill and higher grinding efficiency.
High Production Efficiency
Compared to traditional forging methods, the skew rolling process increases productivity by more than tenfold.
Stable Equipment Operation
Features an integrated roll box design with high rigidity; simple adjustment and ease of operation; secure locking mechanisms ensuring high stability; and quick, efficient guide plate replacement.
Long Service Life
High ball density and impact toughness result in a breakage rate of less than 1% and strong resistance to fracturing, significantly reducing the frequency and cost of ball replenishment for customers.

Packaging and Shipping
For large-scale equipment such as the Ø60 Steel Ball Skew Rolling Mill, we utilize frame-style shipping containers. Motors and precision components are tightly wrapped in plastic sheeting for moisture protection, while exposed machined surfaces are coated with anti-rust oil and wrapped in soft protective material. The entire machine is securely fastened within the transport vehicle; high-strength ropes are used for lifting, taking care to avoid protruding parts. A packing list, product certificate of conformity, and installation manual are included with the shipment.
