Features & advantages

Innovative Split-Design for Easy Transport
Solves shipping and road transportation constraints for ultra-large mill heads (up to 10m), drastically lowering international freight costs and logistics complexity.
Simplified Field Assembly & Faster Maintenance
The precision-machined segmented structure enables easier handling on-site, faster installation, and localized replacement—minimizing equipment downtime and labor intensity.
High Structural Integrity & Heavy Load Capacity
Cast from premium high-strength steel with reinforced joint flanges, our split heads deliver exceptional fatigue resistance and structural rigidity comparable to single-piece castings.
Vibration Reduction & Extended Service Life
Perfect flange alignment and high-precision machining ensure smooth rotational balance, reducing wear on trunnion bearings and extending the operating lifespan of the entire mill system.
