600m/min Corrugated Paper Machine Spare Part Hot Calender
Our 4400/450 hot calender incorporates numerous innovative features that significantly improve paper quality and operational safety. This hot calender dramatically enhances sheet smoothness while improving formation uniformity and eliminating color spots. The hot calender includes an automatic nip-opening system upon web breaks to protect precious roll surfaces from damage. The large-diameter rolls of this hot calender create a wider nip with lower specific pressure, preserving sheet bulk while allowing longer heat contact for fiber softening. A dual safety system on this hot calender maximizes personnel protection, while the interchangeable top and bottom rolls allow selective surface finishing. The hot calender features power load distribution control to prevent breaks during engagement and a belt-type sheet feeding system for safe, reliable operation. With compact design and minimal footprint, this hot calender delivers exceptional performance in limited space.
