ZH-E Double Facer
ZH-E Double Facer
Main Structure and Features
- Cast iron frame, offering optimumrigidity
- Surface ground steel hot plates, 600mm wide, are of S-shape inner whirlpool structure, favorable for steamdistribution
- Individual drive gearbox, featuring transmission stability and lownoise
- Middle support beam holding the hot plate, avoiding hot plate deflection (for wide widthline)
- Combination of pneumatic pressure rolls and dense weight rolls at entrance effectively improves bondingquality.
- Preheateratentranceeffectivelyimprovesheattransferefficiencyandbonding,especiallyfor highGSMpaperboard, therefore to improve corrugatorspeed.
