Steel Ball Skew Rolling Mill Machine

The Steel Ball Skew Rolling Mill Machine is a dedicated forming machine for continuously producing steel grinding balls from heated round steel bars. It uses two inclined rolls with helical grooves to rotate, advance and progressively deform the heated bar into individual spherical balls.

 

 

 

 

Heavy-Duty Construction - Rigid machine structure for stable continuous rolling.

 

Adjustable Roll Configuration - Supports different steel ball specifications.

 

Replaceable Guide Plates - Simplifies routine maintenance and replacement.

 

Automatic Roll Protection - Helps protect the rolls against abnormal resistance and billet jamming.

 

PLC-Based Control - Monitors and controls key operating parameters.

 

 

Rolling Mill Body
Heavy-duty frame supporting the rolling assembly, drive system and adjustment mechanisms for stable continuous operation.

 

Inclined Roll Assembly
Two inclined rolls with helical grooves rotate and advance the heated steel bar through the forming zone.

 

Guide Plate System
Positions and guides the heated bar during entry and discharge for stable rolling.

 

Main Drive System
Provides synchronized rotational power to the two rolls for consistent material movement.

 

Roll Adjustment Mechanism
Adjusts roll position and working gap according to the required steel ball specification.

 

Feeding Mechanism
Continuously feeds heated round steel bars into the rolling zone at a controlled position and speed.

 

 

Heating
Round steel bars are heated to the required rolling temperature according to the steel grade and ball specification.

 

Feeding
The heated bar enters the gap between the two inclined rolls.

 

Skew Rolling
The helical grooves grip the bar and generate simultaneous rotational and axial movement.

 

Ball Forming
Progressive plastic deformation forms individual spherical balls as the bar passes through the forming zone.

 

Discharge
The formed balls are continuously discharged for downstream cooling or heat treatment.

 

 

 

 

The skew rolling mill can be integrated with billet cutting, induction heating, heat treatment, cooling and material handling equipment to form a complete grinding ball production line.

 

 

 

 

Mining & Mineral Processing - Grinding media for ball mills and related equipment.
