3250mm Soft Calender for Paper Making Line
The hard calender roll is designed with a two-in and one-round structure, effectively preventing surface temperature discrepancies. The temperature variation is limited to within 1ºC. As the calender’s heating oil enters from the operational side, a heat insulation device is installed at the shaft head to protect the bearings effectively.
