Super Calender for Paper Making Machine

Product Description:
features

1. The 12 rolls are separately driven by 12 DC motors, which allow a wide rang of speed adjustment.

2. The rolls are made of chilled cast iron with vanadium and titanium alloys. The roll face is hard and anti-wear.

3 The rolls are arranged in S form. Roll 1# and roll 4# have roll cambers that can eliminate bending impact on rolls during working process. Thus, it is possible to make products with same thickness along axial direction.

4The transmission system adopts a hard facing gear reducer, which has a compacted structure with higher transmission efficiency, lower noise and longer service life.

5The machine is equipped with emergency device. When an emergent accident occurs, the calendar will be immediately stopped to open the roll space so as to protect the operator and equipment. PLC program controller is used in electric system.
