Product Description
Rollers for Calender Machine mainly including chilled roll, oil heating roll, steam heating roll, rubber roll, calendar roll and mirror roll, a three roller calender consists of 3 main calender rolls arranged vertically in a stack. The paper web passes through the nips between these rolls under heat and pressure to produce the desired finish.
The rolls are:
Hard Roll or Calender Roll - Usually a chilled cast iron or steel roll that provides high linear pressure and smoothing action. Located as the center roll.
Soft Roll - Made of a compressible cotton, fabric, polymer or rubber covering over a metal core. The soft roll is located on top and helps distribute pressure.
Heated Roll or Oil Heating Roll - A hollow steel roll heated with steam/thermofluids. Located at the bottom.
Mirror roller - used in plastic sheet film, clothing fabrics, leather, paper, metal, film, materials surface calendering, high precision coating.
Advantages of our Calender Rolls :
Improved smoothness and gloss - The pressure applied by the rollers helps smooth out the rubber papar plastic surface and impart a glossy finish. The more rollers, the greater the calendering effect.
Flexibility: Rollers allow adjustments to nip pressure and temperature to optimize the calendering process for different weights/grades.
Durability and elasticity: Steel rollers maintain their shape and elasticity better compared to alternatives like felt belts. This ensures uniform pressure across the width.
Ease of operation and maintenance: Rollers are easy to install, replace and maintain compared to belt or plate calenders. No need for extensive lubrication or cooling systems.
Space saving: Roller stacks allow calendering in a relatively small footprint compared to the length needed for belt calenders.
Versatility: Small diameter rollers can be used for soft calendering without much gloss improvement. Larger rolls apply higher pressure for desired gloss levels.
Energy efficiency - The friction between rollers requires less energy compared to belts which need higher tensioning forces.
