Steel Ball Skew Rolling Mill Machine
Skew rolling with helical groove passes; round steel is rolled into balls in a single pass.
Efficiency is more than 10 times higher than traditional forging.
Product Introduction
The Steel Ball Skew Rolling Mill Machine is a core piece of equipment independently developed and manufactured by Muren. It is primarily used to produce grinding steel balls, bearing ball blanks, and other metal spherical components. Utilizing a helical-groove skew rolling process, the machine continuously rolls heated round steel billets into balls using a pair of cross-arranged rolls, enabling automated, continuous production.

Product Features
1. The ball rolling machine features a cast-steel semi-enclosed frame, ensuring high structural rigidity.
2. Simple adjustment and easy operation.
3. Secure locking mechanism and high stability.
4. Guide plates are quick and easy to replace, ensuring high efficiency and guaranteeing stable, high-efficiency, and high-quality operation of the steel ball rolling line.
5. Mills for diameters above φ60mm are equipped with an electric side-pressure adjustment device, making adjustments less labor-intensive and roll replacement more convenient.
6. Automatic roll retraction function protects the rolls from damage in the event of a jam.
Applications
The produced steel balls serve as grinding media in ball milling equipment across industries such as mining, metallurgy, cement and building materials, thermal power generation, and chemicals. The skew rolling process can also be used to produce bearing rolling elements, automotive parts, and other blanks for rotational components.

FAQ
Q: What sizes of steel balls can a Steel Ball Skew Rolling Mill Machine produce?
A: Our ZQ series covers the full range of steel ball production from φ20mm to φ125mm, including models such as ZQ20, ZQ30, ZQ40, ZQ60, ZQ80, ZQ100, and ZQ120. We can match the appropriate model based on your required ball diameter and production targets.
Q: What is the hourly output of a Steel Ball Skew Rolling Mill Machine?
A: Output varies by model, ranging from 0.5 tons/hour to 25 tons/hour, depending on the steel ball specifications, material grade, and automation configuration. We can provide model selection recommendations based on your annual output goals.
Q: What are the advantages compared to forging or casting processes?
A: Skew rolling is a chipless plastic forming process with high material utilization. The rolled steel balls feature a dense internal structure, precise dimensions, excellent roundness, a surface-to-core hardness difference of less than 5 HRC, and a breakage rate below 1%. Overall service life is superior to traditional forged and cast balls.
