Paper Making Machine Calender Key Features
The distinguishing features of our calender make it a standout choice for modern paper finishing. Primarily, the calender dramatically improves sheet smoothness and eliminates visual defects like cloudiness or color spots. It incorporates an automatic nip opening system upon web break to protect the precious roll surfaces from damage. The large-diameter rolls create a wider nip with relatively lower specific pressure, which better preserves sheet bulk and allows for longer heat contact to soften fibers effectively.
Furthermore, this calender is built with a dual safety system and features a versatile design where the top heated roll and bottom Controlled Crown roll are interchangeable, allowing you to finish either side of the sheet selectively. The integrated control system manages power load distribution to prevent breaks during engagement, and a belt-type tail threading system ensures safe and reliable sheet feeding.
Its technical foundation supports these features with solid specifications:
Application: Optimized for corrugated paper up to 4500mm wide.
Core Design: Features an 11-zone Controlled Crown roll and an 800mm hot roll.
Performance Metrics: Operates at 400-450 m/min with a design line pressure up to 120 kN/m.
Thermal System: Maximum roll face temperature of 180°C, supplied by a dedicated 180kW oil heater.
Build Quality: Utilizes imported hydraulics, high-hardness rolls (>10mm hardness depth), and a compact 6000mm center frame.
Invest in a calender that delivers not only exceptional paper quality but also operational safety, flexibility, and ease of use. Its protective features safeguard your capital investment in rolls, while its intelligent design maximizes uptime and product consistency. Elevate your finishing capabilities and gain a competitive edge in the market. For detailed specifications and to explore a configuration perfect for your needs, reach out to our engineering team.
