Continuous Steel Grinding Ball Skew Rolling Mill

The Continuous Steel Grinding Ball Skew Rolling Mill is designed for high-volume production of steel grinding balls through a continuous hot skew rolling process. Unlike batch forming methods that handle billets individually, the mill maintains a continuous material flow from billet feeding to ball forming and discharge.

 

 

 

 

High Production Capacity - Continuous ball formation supports production rates of up to 25 t/h, depending on ball diameter and machine configuration.

 

Stable Material Flow - Continuous feeding reduces interruptions caused by repeated billet loading and unloading.

 

Lower Manual Handling - Automated feeding, conveying and process coordination reduce routine material handling.

 

Production Line Integration - The rolling mill can be matched with heating, conveying, quenching and tempering equipment for continuous production.

 

 

Continuous Feeding
Heated round steel bars are continuously fed into the rolling zone at a controlled rate, maintaining a stable material flow.

 

Forward Movement and Rotation
The crossed rolls rotate in the same direction, causing the billet to rotate and advance while the helical grooves progressively deform the material.

 

Progressive Ball Formation
As the billet passes through the grooves, it is gradually formed into a series of spherical sections according to the groove geometry.

 

Successive Ball Separation
The connecting sections between adjacent balls are reduced during rolling, allowing individual hot grinding balls to separate and discharge continuously.

 

 

The production flow can be organized as:
Round Steel Bar → Heating → Continuous Feeding → Skew Rolling → Ball Separation → Conveying → Quenching → Tempering

Each stage can be coordinated with the rolling output to maintain continuous material flow.

 

 

The mill is configured for production capacities from 0.5 to 25 t/h, depending on ball diameter and machine configuration. Actual output is determined by ball diameter, round bar size, rolling speed, groove design, material and feeding rate.

 

Actual production capacity depends on the selected machine configuration and production parameters, including:

 

 

 

 

 

 

The rolling mill configuration is selected based on:
Grinding Ball Diameter - Required finished ball size
Round Bar Size - Raw material diameter matched to the forming process
Steel Grade - Material grade and rolling conditions
Production Capacity - Required output in t/h

The rolling mill, heating system and downstream heat-treatment equipment are matched to the target output to maintain continuous production and avoid process bottlenecks.

 

 

Before installation, the buyer should prepare:
